The task was to fill in a gap of a perimeter block development in Munich. The project focuses on the usage of bricks as a construction material. The building contains a show room for bricks in the first two floors. The upper three floors are for housing purposes. Another challenge was to fit in a necessary staircase within a 10 x 10m building area. In this project the staircase is shifted into the backyard to an exterior space. Furthermore this project focuses on detail planning. Not only the construction material of the load-bearing walls are perforated bricks but also clinker bricks are attached to the outer and inner layer of the facade. Another special detail of the building is the steel panel frames which block direct light during summer days. Additionally the exterior lamination provides individual control of the incoming light.

URBAN INFILL The task was to infill, integrate and interact within one of the oldest districts of Istanbul, Galata. At first the analysis showed that recreational space is required within the urban environment. Galata adjoins to the Haliç (Golden Horn) and Galata Bridge. Several transportation systems cross in certain area. All interchanges create an immense pedestrian flow next to the seaside area. The main road is a huge barrier between the hilly upper part of Galata and the flat seaside area. The accessibility shall be increased by public passages and signs.

The long history and tradition of Galata with many small businesses leads to the proposal of a meeting point for the fishermen’s community to give them space for their historically valuable trading goods. The still existing old city wall on the plot represents the strongly connected local community and their long history. The building integrates this part of the ancient city wall and adds new functions such as exhibitions and community work. On top of these two public floors a hostel is proposed. Hereby interaction between tourists and locals increases.

At Munich’s east railway station a school for acrobatic students is planned. Due to current master planning in this area the urban setting of the project is a square solitaire facing the railway side while defining the courtyard of the opposite area. The gym as the main function is lifted up in order to propose a modern typology of the sports hall. Hereby it is taken advantage of the view and light through its overall glazed facade. The lower floors are organized very densely contradictorily to the wide and open hall upstairs. The outer walls are load bearing, which is why the facade is more closed. On ground level the school with study rooms, a library and a computer zone is located. In the 2nd floor the students can live in shared apartments. In between the “base” of the building and the big hall there’s shifted a terrace floor with a cafeteria and outdoor space. It allows the usage as a schoolyard but also a place to linger for visitors of the big hall.

STRUCTURAL DESIGN Klenzesteg

The municipality of Munich plans a new pedestrian bridge over the Isar in between the two main bridges “Reichenbachbrücke” and “Wittelsbacherbrücke”. The main task was to integrate the bridge into the surrounding nature without disturbing the scenery. The proposal is a light steel construction which reflects the arches of its old neighbor bridges. The access to the bridge is barrier-free. Stairs are leading to the green area next to the river, which is a popular leisure area for the people of Munich. Due to existing road flows in the neighboring woods the bridge leans in a slight curve for bicycle riders to enter the bridge most smoothly. Furthermore the bridge is designed with arches as thin as possible so the hydrodynamic resistance is minimized in case of flooding.

elementary school, sport facilities Hannelore Deubzer Sebastian Völkl spring 2013, B.A. 08 Munich
Two solitaires organize the plot into defined schoolyards and provide better orientation inside of the school complex. The functions of school and sports are structurally divided but still communicating with each other. The sport facility will be used by the surrounding communities as well and becomes a new attraction pole for the area. For this reason the interior space concept is based on generous space to welcome interactive communication. The center of the sports hall combines the service rooms in the basement as well as the entrance free-flow area and communication zone on the ground floor. Daylight from the roof creates a rhythmic and active atmosphere while the daylight from the elevated walls create a natural and diffuse light. The elementary school is joined to an historic building protected by the preservation order. On the threshold areas between the old and new building the change of the material to glass emphasizes the entrances. By creating a courtyard in between it is possible to provide the school with natural light and fresh air. Big swinging doors make the threshold of inside and outside floating and create an attractive point of connection. The old building is converted into a cafeteria on the ground level. The rhythm of the classroom’s dimensions is visually recognizable on the facade.
SCHOOL / GYM DESIGN
The topic was to redesign an elementary school and a sports/swimming hall for the Pfarrer-Grimm-School in Untermenzing, Munich. The cleft suburb structure with its unbuilt spaces within the school complex allowed several extensional buildings. Nevertheless, necessary space with a decent learning environment is not provided for the growing number of pupils. Besides, there is a lack of sport facilities such as a gym and a swimming pool. The task was not only to plan extensional buildings for the elementary school and sport facilities but also to overthink the entire unsolved school structure.

FUNCTIONAL DESIGN
A laboratory is planned in TU München’s campus in Weihenstephan. Not only the project is supposed to provide new floor space but also it needs to accentuate and densify the loose urban structure of the campus. This project is referring to the ancient building development of the neighboring mountain’s top (“Domberg”). The sequence of the squares is restored by a L-shaped building, which is precisely placed. It renews the closed building structure, which once existed. The necessary respect for the existing surrounding buildings is given by cutting off the edges. Hereby the cluster and different spaces are formed. The interior space is clearly divided into the inner side to the courtyard and the outer side to the forest. Also, the longer narrow wing with the laboratories and the shorter broad wing with offices, a library and a cafe distribute the functions of the building.

The laboratories are located on four floors. Space for scientific evaluation, facing the relaxing and inspirational view to the Alps, and the actual laboratory area are divided through glass panes. Communication and recreation areas are located at the vertex of both wings and at their diagonally cut ends. The inner facade facing the courtyard speaks a homogeneous language with its fine wooden lamellas. They allow permeability to the courtyard. The outer facade facing the forest is flexible in usage through manually movable wooden elements.

ADDITIVE DESIGN
The goal of the studio was finding a way to accommodate the growing demand of single households in Munich. At first every student designed a collection of floor plans of small dwellings in several dimensions (15m2 -55m2) for different client groups from which later a booklet was made of. Afterwards the task was to design a building in Munich using the pre-designed floor plans. Munich is lacking of solo apartments not only for students, but also for professional workers, single parents and elderly. The picked plot in the very city center demands also public functions.

The “bookshelf” is layered vertically as well as horizontally. It shows its face mainly towards the square on the east to communicate with the public space and people. Therefore the ground floor separates itself into two to lead people through amorph retail areas. The 2nd floor is a carsharing floor for future car reduction. Above the transition zone with cars the private layers with solo housing begin. Housing units are pushed into the bookshelf like books. The diversity in dimension and location provides apartments for any kind of clients. Above the average housing section a special layer is put on top. The duplex housing provides enormous views over the city, with extra terraces. Also on the fifth floor there is a shared room for common usage to play music, games or watch movies. Another highlight also for public usage is the gym hanging down from the roof. Is has a direct view to the square in front. There are restaurants, cafeterias, green spaces and multifunctional spaces for events, parties or outdoor sports on the public rooftop floor.

CLIMATE DESIGN The task was to design a “living-box” for temporary student housing in Dubai. It is saving energy through adapting to the climatic conditions. The living-box works 100% passively. The building shape and skin is reacting to the hot and humid climate of Dubai. The wind tower is an ancient construction in Arabic countries that catches wind breezes and sends them into the houses which is adapted to the climate concept of this project. The orientation of the wind tower was set by the main wind direction in Dubai (north-west). The direction, angle and the grade of opening of the ventilation louvers can be regulated.

An overhanging slab gets the walls shadowed to cool down. The bottom part of the walls have a big thermal mass for protection against the heat during daytime. The upper part is constructed lightly for fast cool down during nighttime.

The house is dug into the ground to cool down the interior room even more. Additionally, cooled down air which passes by cold water in an underground canal leads to the bottom of the house. The combination of the water canal and the wind tower provides a decent room climate.

SOCIAL DESIGN This social design project is meant to provide a product or a service for refugees in Munich. Concepts were designed and tested due to the current political situation. The result was a non-profit organization where refugee women are giving cookery courses to Germans in order to give them access to the society. By giving refugee women a leading role and responsibility as a cooking teacher their self-confidence and self-esteem gets stronger.
TU München Chair of industrial design
Through cookery you learn a lot about a culture and its people. The food is the media of communication. Sharing culture is the best way to understand each other and avoid racism and prejudgments. A key point is to get Munich’s people to participate. Most efficiently you can catch them by provoking and referring to Bavarian tradition and culture. Provoking posters will be hung in public spaces. This should pique people’s curiosity and encourage to visit the website. On the website you get information about the concept, you can sign up for a cookery course and get recipes of past courses.
project type professor team partner period location
Once the cookery course runs well, it can be thought about extending the project with other courses such as music and dance lessons, art and literature courses, sewing and knitting courses and festivals where the results can be presented in public.

In my Master Thesis I tried to fulfill this task through architecture. This design combines the German straightness, consequence, precision and sustainability with the Japanese passion for detail, fineness, lightness and the relation to nature.
CULTURAL DESIGN
Because of my personal cultural background I chose a topic that combines the two cultures of Germany and Japan. Growing up between them means not only to be naturally open-minded towards other cultures but also to understand them in a deeper way. Through the years I discovered several special qualities of both cultures that are sometimes even similar to each other. I see it as my duty to discover and analyze these parallels, cultural dynamics, their weak points and try to improve them through each other.
My personal motivation was to connect the german and japanese young generation with each other through all kinds of art such as fashion design, product design, architecture, music or plastic arts. The idea was born through several conversations I had with artists in Tokyo during my research. Therefore I wanted to give them space to create something new together. To create a space with an informal atmosphere where people with the same interests can unite and defy their different origins also means to support the peaceful coexistence of all cultures.

The concept is to invite artists from Japan to Munich where they can live, create and present their art together with local artists from Munich. The building integrates itself into the artistically developed neighborhood and at the same time emphasizes itself as a Japanese House of Culture. It is an open building to everyone but at the same time provides the necessary privacy for the artists. Producing, exhibiting and holding events are combined underneath one roof so that chance encounter is possible.

Building laws determined the design to its shape, e.g. for light exposure of the neighbors. The long plot shape is made to the design’s advantage in the interior organization. In general open and multifunctional rooms generate an open familiar atmosphere. The garage on the west is combined with the function of a terrace. Long horizontal windows emphasize the length of the narrow house. The construction type is wooden. At the moment the project is put on hold but will be restarted this year.
