NoMAS

Nomadic Modular Adaptive System Academic Project - Bartlett School of Architecture | UCL Instructors: Tyson Hosmer, David Reeves, Octavian Gheorghiu Collaborators: Athina Athiana, Ming Liu Date : September 2019 NoMAS is a digital platform that generates housing communities for digital Nomads. NoMAS is framing a global co-owning concept, developing adaptive housing systems, specific to the needs of every nomad, tackling the problem of traveling and owning. It proposes a new model of ownership based on buying the amount of space that every individual can afford. The space that an individual owns doesn’t have a physical footprint, but a digital one, given the opportunity to the nomad travel all around the world, where the platform provides available places, and still own the same amount of space. In order to do so, it proposes the use of prefabricated components bolted together, shipped, and assembled on site, generating reconfigurable spaces.

The project developed a custom Wave Function Collapse algorithm, utilizing a large catalogue of spatial untis.The algorithm generates valid connected spatial assemblies through constraints. The algorithm was then trained using deep reinforcement learning to negotiate the competing multi-objective spatial requirements and desires of multiple users, NoMAS and physical environment.

The project involves the design of a digital platform that interacts with the user, allow him to ask for his personalized space and negotiates among the user demands, the company benefit and the site constraints. Finally, the user has the ability to select among the possible solutions that the platform will generate or select the company’s offer, that would satisfy less his demands but be more affordable.

Between the Pumice and the Aegean Landscape: Resort and Thermal Baths at Gyali, Dodecanese Diploma Design Project - Aristotle University of Thessaloniki Instructor: Spyros Papadimitriou Collaborator: Maria Petrou Date : June 2018 The project proposes the design of a resort with thermal baths at the desolate island of Gyali in Dodecanese, Greece.

Gyali is a volcanic island and is regarded as a part of the neighbouring island of Nisyros. The island comprises a peculiar landscape overall, consisting of rhyolitic obsidian lava domes in the northeastern part and pumice deposits in the southwestern part. It has a population of 12 people, who work as miners at the two mines operating on the island.

The project covers an area of about 5000m2 at the southwestern part, which is undergoing pumice strip mining and aims to rehabilitate the site after the mine operation, by creating a resort with thermal baths, utilizing the healing sulfur waters of the area.The pumice landscape, a valley and surrounding hills, alongside with the remnant of the mining activity and the sea water are the dominant elements, giving the area a unique identity. Thus, the building complex is located on a hill, lying halfway between the coast and the valley, with the accommodation units being on the southeastern part of the hill, in connection with the beach, and the rest of the facilities on the northwestern part, looking at the valley.

The adaption to the natural inclination in combination with the creation of different spatial identities were the starting points of the proposal. The design of the complex is based on the vertical surface as an element, noticed as dominant at the settlements of Nisyros. Thus, surfaces are combined in different forms and sequences, in order to border the connecting routes among the different buildings and at the same time enhance the spatial experience by creating focused views, visual continuity or discontinuity, imposing or subtle boundaries. The facilities on the two sides of the hill communicate through underground connections, commenting on the mining activity. connection

Water is considered to be a symbol of mental and physical healing and thus, combined with the therapeutic properties of sulfur led us to design facilities and activities aimed at treating body and mind. The activities are mainly outdoor, while the resort facilities include the reception, a shop, 33 accommodation units, thermal baths, a restaurant, a library and auxiliary spaces all of them in separate buildings –variants of the original accommodation unit.

Encoded Assemblies Academic Project - Bartlett School of Architecture | UCL Instructors: Tyson Hosmer, David Reeves, Octavian Gheorghiu Collaborators: Athina Athiana, Ming Liu Date : December 2018 The project investigates Cellular Automata and specifically Conway’s game of life. Game of life is an infinite two dimensional, orthogonal grid of squares, representing cells in two possible states – alive or dead. Every cell interacts with its neighboring cells and according to some specific rules retains or changes its state.

By using Game of ife in three dimensions, analysing generated quantifable data and modifying the game rules, the project gains control over the states of the game towards generating desirable results that assimilate table structures. Furthermore, it explores the potentials of improving the solutions, implementing intelligence to the model through a genetic algorithm.

22

Game of life was the starting point, in order to evaluate three dimensional structures, or stacks. This was achieved by setting some specific grid boundaries (dimensions) and extracting every new state of the grid upwards, so that each new state represents another layer of the stack.

3D GAME OF LIFE

STACK

During the analysis process, cellular automata behaviors were exmined according to some sets of parameters. These were :

CELL LAYER

ALIVE || DEAD CELLS

- The seed of the stack, meaning an image at the dimensions of the grid in which we tested from simple examples as dots and lines to more complex ones, combinations of them.

- The different interacting neighbourhoods - Different sets of rules – for alive and dead cells-, and according to them - Quantifable features as local or global density, age, and relation between the seed image and the stack, which will be explained in detail.

After the detailed analysis of the input parameters and the different behaviours of the design model, the metrics were used as a feedback mechanism in the triggering of local rules in order to develop a controlled growth model.

Specifically, the selected rules were grouped in 3 sets, according to the density values they produced, and different density and layer thresholds 26

After that and In order to automate the process of producing stacks with different features, according to quantifiable data, a genetic algorithm is used.

SURFACE - LIKE

The genetic algorithm was implemented to the three dimensional structures in order to produce desirable forms with specific features.The desirable output was a table – like form, which was translated into quantifable data, that were intended to achieve.

MODERATE- LOW BODY DENSITY

In order to achieve this, the two dimensional patterns that can be produced by all the possible alive and dead cells combinations in the moore R1 neighbourhood were evaluated. The fitness function was chosen to be related with the patterns of the less alive cells, so that a low global density value could be achieved, as well as with some specific patterns of more alive cells, which were expected to attribute more stability to the structures.

Three sets of rules from the previous analysis process were selected to be used as genes, with low, moderate and high average density values, which are locally controlled through the fourth gene, a density threshold, related to the previous layer density in each case.

Interactive Optical Device Design studio - Aristotle University of Thessaloniki Instructors: Spyros Papadimitriou, Dimitris Kontaksakis Collaborator: Maria Petrou Date : June 2016

The project focuses on the research and design of a ‘deep’, interactive surface which is formed to shape the shell of a hybrid existing building in the center of Thesssaloniki, Greece. The 8-storey building is also designed in the interior and attributed to use.

30

The design process begins with experiments on concave and convex semi-transparent mirror surfaces to extract principles about the reflections and reformations produced when a light source includes on them. These principles are used to produce a digital dynamic model -mechanism that will form the ultimate form of the shell by trying different variables.

convex

convcave

Experiment A

The first experiment examines differences in the reflection and reformation of a certain light source on concave and convex surfaces of equal circle radius and curvature size in each case. The outcome is that the light is reflected equally but in the opposite angle of the surface comparing curved and convexed ones.

The second experiment examines differences in the reflection of a certain light source on curved surfaces of equal circle radius but progressivly increasing in curvature size. The outcome is that the light reflection covers a progressively larger area of the surface, as the curvature sizes increases.

lighting

Experiment B 31

shadows

The dynamic digital model-mechanism is developed on the basis of a rectangle divided threefold both in x and y axis.

The nine centers of the new rectangles are the variable points while the junctions of the grid constitute the stable points. By changing the variables along the z axis different surfaces are generated, producing different reflections and reformations. These surfaces will be used in the next phase as the units of the ultimate shell .

Taking into consideration what the area needs, the building is attributed to the use of a new kind of hotel that meets the demands of constantly-travelling people, who replace home with the hotel environment. Thus, it is designed to provide affordable comfort to rooms and public spaces, by minimizing unnecessary staff and removing useless furniture. Accordingly, the ground floor and semi-floor are covered by different kinds of cozy living rooms and a bar , while in the next 7 floors there is one kind of room dominated by a king-size bed with a shower and a lavatory , which are grouped in zones for every two rooms. Floor 8 is designed to provide work space and meeting rooms with a panoramic view of the city.

Each glass panel of the shell assimilates a surface produced by the mechanism designed in the previous phase. Three kinds of such panels are used, referring to the altering variables and grouped to organize the building shell in horizontal zones. Exceptions are three points, where similar formed panels are placed vertically, in order to mark the entrance and the two endings of the aisle outside the rooms. The different kinds of curved surfaces as a whole aim at producing an eye-catching visual effect and monitoring the relationship between the inside and the outside of the building.

Aqua Destino Workshop project- Bartlett School of Architecture Instructors: Vallie Alamanou, Mikaela Psarra Collaborators: Evgenia Krassakopoulou, Konstantina Bikou Date : September 2018

Aqua Destino is an underwater garment, designed during the workshop ‘Digital Textiles’. The proposal is based on the design of a “breathing” textile, that has the ability to absorb and eruct water, waving and accelerating the underwater movement.

Main element of the proposal is the design of a component in a hydrodynamic shape, that can be combined in different scales and patterns to form the overall garment.

Nature & Space Constructions Design studio - Aristotle University of Thessaloniki Instructors: D.Kontaksakis, N.Tsinikas Collaborators: Maria Petrou, Fenia Papadouli

Date : June 2017 The project involves the design of three space structures in relation with physical forms, inspired from nature and biology. The first conceptual idea is based on a treelike structure, the second on a tensile membrane and the third on an inflatable sphere, while all of the models have as a common the integration of a kind of grid in the structure, as an element found in various forms in nature, as well as in microorganisms in the microscope. The construction of a model in each case is followed by giving a potential use to the structure in the public space.
