6 Introduction to architectural design “The Cube” (2003)

This project, as it is indicated by the title was undertaken in order to introduce the students to the architectural design. The project starts initially as sculpture. A Cube with certain -givendimensions (16cm) is constructed, so as to have the initial material with which students had to start working.

The first phase has to do with a “synthesis” in the three dimensional space. I had to transform the Cube by adding or deducting any parts, or

I had to place the structure into a specific field and to treat it as a house, trying to morph the external layer using for the first time connotations such as “vacancy” and “fullness”. Simultaneously I had to work with the internal space, trying to create viable and practical environment for a family of three. even only by changing its very specific form. The desired result, should be a synthesis that could stand alone in the environment and simultaneously to bare a significant interest.

Once this project was completed, I had to pass to the second phase, which was nothing more but to consider the previously produced sculpture as a house, again with certain dimensions.

The acme of 16cm of the initial creation would stand for 8m of actual size of the second phase’s “house” (scale 1:50).

8 Nature and Spatial Structure (2005)

This project aims to deal with “light” structures-facilities. As “light” constructions, are defined all structures that are made piece by piece and can be put or removed several times in the same or in a different place. Usually, they are made by light materials too, such as iron, wood, plastic, glass and fabric.

The use of such structures differs according to the occasion, the size and of course the place that are being constructed. A bus station, a flea market, an alley or a ceiling are only some of the indicative uses that were suggested. The whole concept here was to search for direct references in nature’s formations throughout fauna and flora so as to correspond in design mode our structures with these nature formations and shapes. Despite some functional differentiations, all projects were to be used as ceilings portable or static. The aim of this project was to familiarize students with complicated shapes such as the “hyperbolic parabola”; learn how to design them in the first place and in sequence how to make them feasible and appropriate for construction. The project, involved only model making as the mathematical description and the digital design of such models was quite complicated for the moment and the average knowledge level then.

10 Small Hotel with Spa and Restaurant (2005) The area to be studied, is located in a suburb of Thessaloniki called Thermi next to a lake with rich fauna and flora. The artificial lake is formed due to an artificial dam near-by. The field has a great view to the lake and a smooth inclination slope. The project is about a hotel with a small spa and a restaurant.

The spa facilities had to be embedded to the hotel in contrast with the restaurant which had to be more independent so as to provide its services not only to the users of the hotel, but also to visitors. Nine years ago, the intention for artificial structures became more evident across the lake’s coastline, and resulted in a children’s playground so as to an outdoor refreshment utility, a café.

The basic principals for this very project were initially to create something that would exist in harmony -and not in controversy- with the surrounding environment.

Therefore it was attempted to create two qualities of space. One, semi-subterranian in order not to change much the shape of the natural ground together with the memories of the local habitats for the landscape. And another that would elavate the ground level of the building so as not to be “ground”, in order again to have the less impact with the natural terrain. The whole synthesis was decided to be orientated to the spot of the greatest optical interest, the island in the middle of the lake. Through the final result, it is profoundly evident that the VIEW was the factor that affected the designing proceedure to its most.

The whole complex is suitable also for people with special needs, a fact that is also indicated by the special design of a small number of rooms.

12 Conservation and Restoration of Monuments and Complexes (2006) This project was focused on the restoration and reuse of a historic building of Thessaloniki. The chosen building was an old house in the center of the old Jewish neighborhood, built in 1911-1912. During the first phase of the project, the students analyzed thoroughly the historic background, the typology and the morphology, but also the present state of the building.

The results of this analysis were handed in as a report, along with the relative documentation. The objective of the second phase was to suggest a new use for the building and propose the necessary restoration points and changes. Additionally someone could use the of-no-use attached site which didn’t have any historical interest, in order to support his proposal, but also to restore a previous look of the block of the neighborhood. The principles of the proposal were in harmony with the building’s history and form, while attempting to reintroduce this very building in the contemporary environment.

More specifically, the building was in a very bad condition and apart from the ground level storey, was not used. Therefore, a new use that could reclaim the building in its integrity and simultaneously

to introduce it again to the new situation of the neighborhood as far as its use was concerned, was proposed. The old house was reused in order to serve amusement purposes, thus several spaces were created such as a Cafe, a restaurant, and a bar.

Regarding the existing building, the remaining architectural and decorative elements were conserved and restored. The new added building aims to be supportive to the old. It tries to state its presence in dependence to the old one, but also along. It is a new part of something old, but both of them are a dynamic complex. It is made of contemporary materials and simple design, in order to be easily discriminated from the existing building. The proposal for the new use is loyal to the spirit of the neighborhood, nowadays.

14 Landscape Architecture Stream Restruction (2007) The main aim of this project is to create urban openair spaces for collective activities. The site is a glen within the urban tissue of Thessaloniki, neighbor to the urban forest of Seih-Su. In effect, this site is the upper part of a unique axis that joins optically and actually the forest of Seih-Su with the sea. Due to the terrain formation –of great changes in height- the upper part of the site seems to be the most appropriate to enjoy the view. Following the inflow of the glen and planning different qualities of space –with respect to the natural terrain formed by the glen-, someone can walk parallely to the glen, but also find places to gather, enjoy the view or further more to watch an open-air theatrical act or even an exposition. The axis whose upper part is our site of interest, is defined by the buildings whose use is really compatible with the uses we want to apply. There are the three major museums of Thessaloniki, the biggest convention center, the new town hall, the international fair of Thessaloniki, several sport fascilities and the Aristotle University Campus. Besides this axis is one of the few that the presence of green is noticeable. The creation of an attractive space that would provoke the citizens to create different scenarios of life, was the main goal during the synthesis procedure. Taking into account the urban tissue of the produced environment, we tried to keep the main routes through of which the users used to cross the site. The aim was to blend the new planning with the surrounding area and of course to keep –at first- and then to add the green element that the city of Thessaloniki lacks so much. The whole project is studied as to be appropriate for people with special needs.

18 An Environmental Approach in foreign student’s residence project (2007-08) (1/2)

The design of a foreign students’ dormitory with an environmental approach, is the aim of this project.

It specifically refers to foreigners because as it was found out, the rooms offered today by the state, are not enough to hospitate the whole amount of the foreign students in Thessaloniki. This decision had a significant impact to the design procedure, concerning especially the dimensions of the rooms -small rooms that are suitable for short term use-.

The second in the row but not in significance principal that was taken under consideration was the environmental behavior of the complex. Thus it was decided to maintain the buildings that could reach the standards of this new -for them- direction; and to create new that would contribute essentially towards the energy efficiency of the whole project.

The building plot is confined by the streets of N. Egnatia, 3rd September and Gr. Lampraki. The specific site is exactly opposite the University’s campus. Today the specific area is taken up by four army residential buildings, Gymnastics Academy department’s facilities and free space for parking. The proposal involves the creation of a residential building block for 116 Erasmus students, including: 100 single rooms, 8 double rooms, 8 university dorm rooms for guested groups or professors, common rooms (lounge, cafeteria, reception, exhibition room, meeting room, surgery, day nursery) and a parking lot.

The 100 single rooms occupy the south-eastern side where the Gymnastics Academy facilities previously existed. The rest of the students’ rooms and the common rooms are placed in the four central buildings, which are reformed and unified (through the creation of a glass roof between them), so as to serve the new needs, maximize their energy benefits and shape forms that fit the cluster. Finally the parking lot is placed in the north-western side, at a downgraded level, with enough room for 50 vehicles.

The environmental design strategies are applied both regarding the area as a whole in order to affect its microclima and at the building units separately.

Thus, altogether, it is sought: a) cooling through the extensive use of water b) gathering rain water from the building roofs c) saving water through the creation of biological treatment facilities and d) saving energy by using photovoltaics. All the necessary technologies, and their extend were calculated up to the point that would affect the architectural design, in accordance with the climatic data for the specific area, provided by the national meteorological organisation.

20 An Environmental Approach in foreign student’s residence project (2007-08) (2/2) Several different strategies were applied at the building units in order to serve the particular needs and to avoid a result strictly depended on a southernorientation-based design, which is a very usual but not so successful practice in Greece. Thus different types of heating/cooling facilities such as geothermy and solar collectors, as well as various other strategies like cave houses, solar spaces, green roofs, sun protection, ventilation corridors, compact masonry and thick insulation were used for the creation of an energy efficient and environmentally principled residential block.

22 Altered architectural practices in the area of Foinikas, Thessaloniki (2007-08) (1/2) This research project is an attempt to gather all the alterations that occur in the urban landscape and additionally to interpret all these social and psychological characteristics that provoke these changes.

In degraded and marginalized areas, where the means for a complete handling and a total solution are extremely limited, the needs of the users and their depiction in the environment are more intense.

This is the reason, that we pick Foinikas Thessaloniki, a neighborhood that accumulates such characteristics, and after gathering the necessary data, we compare it with other sites in and out of Greece.

Foinikas is simultaneously the east entrance of the city, through of which passes the main -and onlyroad that connects the city with the only airport. It is known,that in such places there are many possibilities for commercial development, which bare to the area a promising perspective, and to this research interest.

As for the method which is used to reach to conclusions, there are three basic distinguishable sections: a) The theoretical backup. Bibliographic research, which aims to find the necessary theoretical filters that would support our assumptions. We find the component of all these political, social and psychological characteristics through of which our perception for the site is filtered. b) Collection and presentation of elements of the site. Recognition and analysis of the area of Foinikas.

Use of historic, urban, economical and social factors that affect the form of the area. Thorough collection and categorization of the alterations that have happened to the area. c)

B) The space is Reproducing. The formation of a space is not terminated after the end of its initial design and the actual realization of the plans. The user forms -by his/her existence- the environment so as to make it appropriate to satisfy each need that may have, and also to fulfill its future dreams. As for the interfering of the user with the urban space, the kind of the consumption and consequently of the alteration of this very urban

Explanation and conclusions.

The urban space is modified in two ways: A) The space is produced. Space according to H.Lefebvre has different substances: 1) The natural, the real one, this that people realize through their own senses in three dimensions.

2) The conceptual one, this in which people realize memories, feelings and signs. The place of a surgery for example, being the same place for every user of its, for some is their working place whereas for some others could be the place of a resurrection.

3)The social one, meaning the projection of the society on the structured space, and the activities of its members, either they are expressed collectively or individually. Several examples could be found in Michel Foucault’s work, such as “Panoptikon”, where is introduced a spatial model, of a strengthened central authority that controls other cells, equal between them, but weakened compared to itself.

space, is dictated by a net of social, moral, economical, cultural and psychological characteristics. People do establish relationships with the environment, and these relationships have some indications through of which someone can evaluate the different qualities of the environmental space: (1)”The personal space”, (2) “The privacy”, (3) The need of feeling that owns a piece of space against other possible users -a very typical behavior to the carnivore mammals that form teams and societies-, (4) “The overcrowding”, are some of them.

When all this huge discussion comes to Housing, becomes really imminent to define the meaning of housing today. The role of the house nowadays is double. Always has worked for the family as a shelter, that could protect it so from the climatic changes as from hostile attacks also, when simultaneously was providing the most -by definition- familiar place to fulfill all its social, psychological and emotional needs. Today though House works also as a sign. A sign of social recognition for example.

When it comes to Worker’s Housing though, the situation, or better the concept turns actually to be the minimum house for “the middle typical worker”, same throughout the world, “ideal” for “the average user” that eventually didn’t live anywhere anytime.

1) The damage. In this category are included examples of disaster of the external surface of the buildings, of such an extend as to demonstrate a completely altered “being” compered to the original plans.

2) Decoration. In this category are included examples that occurred due to the aesthetic criteria of its user. These changes could also have a more practical effect, such as the replacement of the windows.

Foinikas is a complex of Worker’s Housing Buildings, that was built in 1961-63, and until today is separated from Thessaloniki so actually as also conceptually. In Foinikas today there are about 4600 citizens in vast majority of which are emigrants. The whole situation is a bit problematic , because of the unemployment, the low educational level, and the overcrowding.

In Foinikas are distinguished six main different types of buildings but also a rich variety of the typology of the today’s houses. This controversial fact takes place mainly in the inner of the houses, where each type of building seems to have undergone several alterations.

As for the large scale interference in the macro-environment the situation is rather discouraging through its absence.

As for the small scale interference in the micro-environment, the alterations that are marked, are grouped in 4 categories:

23

24 Altered architectural practices in the area of Foinikas, Thessaloniki (2007-08) (2/2) 3) The exploitation of the property. In this category are included examples that occurred due to the need of the users for more space, which the responsible organizations seemed unable to offer in a systematic mass level one way or another. Such examples would be the creation of a garten in the basement, the addition of some rooms, or even floors.

4) The sense of comfort. In this category are included examples that have to do with mechanical equipment, such as an elevator, a natural gas heating system and advertisement panels.

28 Building Fabric (2010) Individual assignment The aim of this module is to familiarize the students with the attributes and the potentials of the building’s fabric. In the context of balancing the conflicting requirements of thermal, visual and acoustic comfort and air quality with the desire for efficient heating, cooling, lighting and ventilation, this module introduces the principles and the methods for assessment of performance of the building fabric. Additionally, it introduces a range of novel and classic techniques, as well as passive design strategies, for successful fabric design.

The thermo-physical properties of the building materials, the thermal and visual parameters of the glazing, the climatic characteristics are presented and in sequence applied in the two different assignments. The first one is a group assignment requiring broad research of a specific issue culminated in a 15 minutes power-point presentation.

Integrated Photovoltaic elements and techniques were studied and presented consequently. The second assignment was individual and required the study of a particular issue, the daylight performance, the solar performance, the acoustics or the ventilation along with the thermal performance in a building of our choice. The selected building is a public building of the Aristotle University in Thessaloniki, Greece. The Mediterranean climatic conditions are imposing cooling and heating strategies on an annual basis. The other parameter that is chosen to be examined is the daylight factor and performance of the building.

30 Low Carbon Footprint (2010)

Low carbon design requires an holistic approach to the energy use of a building. This requires designer to understand in principle how buildings use energy and to supplement this understanding with evidence on energy use from the field. He or she needs to be able to work with goals for building design, such as zero carbon standards, and with ways of off-setting energy consumption with renewables. The main aims of Low Carbon Footprint module were initially to introduce the ways buildings use energy. Additionally, to present methods of matching these demands through renewable and low energy systems, and in sequence to introduce all these techniques for assessing the energy footprint and sustainable performance of the building using benchmarking and monitoring. Issues like the demands and loads of energy consumption in buildings as also the impact of the occupancy levels and patterns on this very consumption were thoroughly presented and applied in the different assignments. Furthermore, many other fundamental terms like the renewable technologies, the low energy cooling technologies within buildings, the embodied energy and zerocarbon buildings are well examined. Many reliable calculators and assessment criteria for the sustainable design are provided. The assignments displayed below were carried out in terms of assessing the impact of the various building services options on different building design problems. The first assignment required the research and critical evaluation of the carbon footprint of a building element. For the selected element, at least two different materials or construction methods were to be considered and a conclusion as to which would be preferred in terms of carbon footprint and why should have been reached. In the second assignment, a report considering a design feature such as the natural ventilation, the passive solar gains, the ground source heat pumps or the wood fire boiler of the “Senedd� Building (Welsh Assembly) of Cardiff, had to be written. In the last assignment, a low carbon house in UK had to be constructed (virtually) with an 80% reduction of its Carbon dioxide emission rate compared to one equal house of today (built in 1938). In this last and most important assignment, a SAP 2005 document, a Wind turbine calculator (excel spreadsheet), a SAP worksheet 981 (excel spreadsheet) and a photovoltaic’s calculator are provided in order to reach the defined target and in sequence to assess the validity of the proposal.

32 Environmental Design Practice (2010) (1/2) First episode 1 This module concerned a project that was carried out individually. The aim of this module was to put in practise all the gained (from the simultaneous modules) knowledge, take decisions and produce evidence upon their feasibility and efficiency. The module was divided into three stages, “episodes” each of which concerned a different aspect (or stage) of the holistic approach on the concept and realisation of a building. In the first episode, the site environment (unfamiliar to each and every student) in terms of the climatic and social influences, was studied. A thorough research upon the climatic data of the area and a proper interpretation was made, so as to support the proposed use in a certain place (within the original site). The decision upon the location (within the site) of these activities, was again justified but the climatic data of the area as also by the geomorphic circumstances of the terrain. The limited moderation of the existing environment along with the minimal intervention in the build landscape was the desired requirement. The arguments supporting the proposed location and use had to derive from the use of the relevant software “Ecotect”. In this stage, a site in Mumbai, India was chosen to facilitate traditional workshops of music, dancing, body painting, clay pottery and wood and stone carvings.

In the second episode, the potential reduction in energy consumption with the use of fabric for a specific building and site was required, as a sequence from the first episode. The interpretation of the climatic, social and other environmental data, useful for indicating design objectives, was applied, along with the implementation of design strategies concerning daylight, heating and cooling, adequate for the site and the building. An evaluation of the environmental performance of the building was carried out, in order to support the primary decisions made for the design and realisation of the building. In terms of this second episode, the building that is proposed lays below the earth utilizing the beneficial effects of the seasonal and diurnal changes in the ground temperatures. Furthermore, the “matchbox” utility, the possibility of using different parts of the building at different months of the year, like a drawer or a matchbox moves inside a concluding shell, is proposed and successfully applied.

In the third episode, the building services were to be studied. The dependence of the service loads upon the use, the form, the fabric and the setting of the building was studied thoroughly and in sequence an estimation of the building service loads for the particular building proposal was made. All the necessary changes considering the form of the building and mainly its fabric were made parallel with the installation of the necessary –for the building and the climate- building services. The overall efficiency of the services of the building was calculated and presented to support the initial decision concerning their installation among others. In this final episode, the original building had to be brought on the surface and there to be solved as a new building.

36 Environmental Design Application (2010) (1/2) Poster 1

This module concerned a project that was carried out individually. As the final design project of the Master it could be considered as a mini dissertation project, provided that students could research in greater depth a problem, design feature or building. More specifically, the aim of this module was to test in practice the ability to apply in practice what was taught in the sum of modules. The project takes the form a design study of a certain aspect of environmental design. Below is presented the case of “Foinikas, Thessaloniki”, a social housing complex created in 1962-1963. The poor construction and materials used along with the deficient or absent maintenance, shaped a housing complex with huge energy demand, used mainly to cool itself down. Therefore, among the different building types two are selected and further studied. Each of these two building types is grouped further considering its orientation giving two more categories: a) eastern and b) eastern-south-eastern for the 1st type and c) southern and d) south-western for the 2nd type. The above categories were obviously chosen compulsory, as the study took the form of a refurbishment procedure into an existing building. The features to be studied were carefully chosen after eliminating other passive design techniques and features that would be less adequate and consequently effective.

The form of the building types, the peculiar, though specific ownership/property status of the houses, the economic power of the residents, the climatic conditions, the orientation and the geographical position of the buildings in the complex are examined and in sequence a solar chimney for the first type and an atrium for the second are proposed and evaluated.

The hottest peak and average days are studied for the two passive design features mentioned above, so as to test their effectiveness in terms of their ability to cool the surrounding -to them- enclosures with displacement ventilation. In addition to these, an underground pipe system is proposed in order to provide buildings with air in a modified -compared to that of the air of the exterior- temperature with minimal use of energy. The effectiveness of the atrium and the solar chimney are tested on the basis of how many ach (air changes per hour) they can cause to the enclosures on key-hours of high external temperatures. Additionally, due to the presence of the underground pipe system the temperature of the air entering the buildings could also be adequate for heating purposes during winter time, as it follows the ground temperature calculated by the “Kasuda equation”. The whole process is driven naturally only by the sun, which as it is known but also proven with sun-path diagrams and shadow masks illustrations, is plenty in Greece. The overheating problem during summer season in the Mediterranean as also the urgent need for refurbishment in many cases, are rather common, therefore this study could be considered as an investigative tool for the examination

of a higher-level problem. For the completion of the above study specific software was used. The modeling of the enclosures conducted with the use of Ecotect, applying the original weather conditions of Thessaloniki and getting valuable data concerning the solar radiation and the air temperature. Additionally, a sensitive CFD analysis took place with the use of Winnair, in order to measure the performance of the solar chimneys and the atriums.

42 Dynamic thermoregulation in the building’s envelope with the use of water (2010) (1/2) This dissertation is an attempt to investigate the potentials of building’s fabric as a filter for thermoregulation. In this attempt, the relevant literature is reviewed and a range of active systems that are integrated in the fabric of the buildings is presented. Recognizing a gap in the philosophy of utilising the beneficial properties of the building’s envelop, main filter for thermoregulation applications for the creation of a comfortable environment, the modeling and simulation of a wall embedded heating and cooling system with water, is made. Different methodology scenarios are applied so as to unveil the critical aspects of the performance of such a system. The ratio of the lateral surface of the enclosure towards the volume of the air of the interior, the height of the enclosure, the presence of insulation, its position within the building’s envelop are studied thoroughly in order to understand the thermal behavior of this wall embedded heating and cooling system along with the produced conditions of comfort. Finally, suggestions concerning the performance and the efficiency of the system are made as a conclusion.

More specifically, the main thermo-regulating systems that are embedded in the fabric of the buildings are compared and contrasted in a productive way so as to spot the comparative advantages and disadvantages amongst, concerning their performance and efficiency. TermoDec, chilled beams and ceilings, under-floor heating systems and wall embedded systems are reviewed as described above. Furthermore, a wall embedded heating and cooling system is proposed and tested. The assessment of the specific system required a certain methodology described below and some specific thermal simulation software as Ecotect and HTB2 (equivalent to EnergyPlus).

Initially, it is considered a weather profile with high annual temperature differences that would cause to a building the need both for cooling and heating throughout the year. For this reason, the Mediterranean climatic zone is chosen and specifically the set of the climatic data (weather profile) of Athens.

Afterwards, a series of different scenarios are considered so as to lighten the ways that the wall embedded system works.

There are three enclosures considered: a) 5x5m, b) 10x10m and c) 20x20m, so as to simulate the dimensions of a room, an apartment and a typical open plan office storey.

The system is placed in the walls of the perimeter, assuming that the enclosures are placed in the first floor of a multi-storey building and exposed directly to the present weather conditions through these four walls.

Apart from the length of the sides, the height is also changed from 3m to 6m so as to change the ratio of the lateral surface (where the wall embedded water system is placed) to the volume of the enclosures.

mining factor considering the efficiency of the system. Despite the fact that the ratio of the lateral surface of the enclosure to the volume of the enclosure remained the same, in the higher enclosures the efficiency of the WEHC system was decreased.

Last but not least, is the dependence of the WECH system upon its relative position inside the wall. The thermal effects of the system differ when it is placed a) just before the finishing layer or b) after the insulation layer in the center of the wall.

Each of the 6 enclosures now, is equipped with a water heating and cooling system embedded in the walls of the perimeter.

Initially none of the walls contains an insulation layer. Secondly, an insulation layer is added in the center of the walls and the water system is placed just after this layer towards the internal surface. In the next phase, the ductwork is being placed just after the finishing layer of the internal surface. Finally, the performance of the system is compared to an HVAC system of the same power for each enclosure. A free-running type of all the enclosures is also monitored so as to appreciate the proper function of the systems along with the establishment (or not) of the comfort conditions inside them.

In conclusion, many aspects of the application of such a sys-

Hence, there is not a specific conclusion upon the nature of the dependence of the WEHC system’s efficiency and its position in the wall. The enclosures are monitored hourly for all the days of the year and in sequence the conclusions are drawn for the coldest and the hottest day (peaks) and for the cold and hot seasonal average. Despite the fact that there is a variation in the thermal effects of the system depending on its relative position, an exact relationship between the two variables is not established.

Finally, the idea of placing a system in the envelope of a building for combating the weather conditions when necessary before reaching the interior could be a promising one. Further research is required to study many more important variables that contribute positively or not to the efficiency of the system.

Additionally, the possibilities of connecting such a system

tem are lightened. Initially, the presence of an insulation layer was proven vital for the better efficiency of the wall embedded heating and cooling system with water. The dimensions of the enclosure are extremely important for the application of such a system. The size of the plan of a building is inversely proportional to the efficiency of the system, reaching its limit for enclosures with side greater than 18-20m. Height is proven to be a deter-

48 Small private medical centre for two pediatricians (2009) (1/2) This project started in October of 2009 and lasted 9 months, due to some financial difficulties. The whole space includes three separate rooms, a bathroom, a kitchen and a living-room. The aim of the project was to transform this apartment into a practice for two pediatricians. Two of the rooms would stand for the separate private places in which each doctor examines its patients. The third room would serve potential mothers and their infants for the breastfeeding as also the secretary-nurse who would prepare the following patients for the doctors to examine.

In the bathroom it is placed a piece of furniture in order to help mothers with the cleaning procedure of their babies. The common waiting room -former living room- gets separated from the kitchen and facilitates three activities-uses: The secretary with the necessary furniture and the rest waiting room, which is divided in two zones. One zone is attributed to the children providing space and materials for several activities while waiting and another zone for their parents. Kitchen is separated from the rest room due to aesthetic and functional reasons.

The idea was to keep a low budget for the whole project, due to the fact that the employees are new-workers. I was assigned to design the whole space, except the one private room for the one of the two doctors, that had already signed a contract with another colleague before. Under the close observation of my clients, I tried to create a pleasant space both for children and their parents. The aim was to produce a colorful environment that would maintain its “practice� attitude. The concept was the same, for the individual room I designed for the doctor. I designed all the pieces of furniture and I chose the colors carefully so as to comply with the European Health and Safety Regulation for medical practices. I decided to create stencil pictures on the walls, an idea that afterwards applied in the reception room also. All the pieces of furniture, so from the waiting room as also from the individual practice, are designed so as not to be hazardous in any case for the children.

Additionally, a simulation analysis concerning the daylight and the solar radiation was carried out.

Some primary conclusions, concerning the use of the shutters of the windows and a night ventilation schedule are applied with beneficial for the enclo-

52 Housing Project - Interior Design (2009) As indicated from the title, this project was about a remodulation of the internal space of a previously built house. The main idea here was to reform the inner space in order to make more practical and functional. The clients here wished mainly for separation between their kitchen and the living-room. The barrier had to be more optical rather than actual, so as to hide the kitchen from a visitor. Additionally there was a restructure of the fire-place and the tvset along with the furniture which already existed.

The idea here was to create a viable environment, that would make it easy for the owners to live and to move inside this space. Here their interference which was not at all discreet, was applied mainly to the colors that they chose. At this point it should be pointed out that none of their pieces of furniture should change. Everything should have to be reused.

54 Housing Project - Block of Flats (2006) This project took place on August 2006. I was assigned to design a block of luxurious flats in Thessaloniki, Greece. The project (brief) required the design of a block of flats in the eastern entrance of Thessaloniki. The client wished for a building, landmark of the neighborhood. The building’s site was the first in a row of buildings on the main avenue of Thessaloniki and therefore difficult to be missed.

The client wanted to take the maximum advantage (permitted by the Greek Building Code) of the use of the basement and therefore wanted to use the maximum possible coverage of the site. Additionally, according to the brief of the project and the permitted size of the structure, the building would facilitate some offices and of course housing. The client decided to keep the last apartment for himself and therefore asked for a pool. Each storey had a surface of about 100 m2 and would be used as an only apartment. The basement would be used as a store for furniture, and the first two storeys as offices.

The proposal was considered quite pioneering for the time being considering the rest urban tissue of Thessaloniki and exceeded client’s expectations.
