Density Bachelor Thesis

Lubomir Peytchev

The site is on the north part of the Lohmühlen-island, facing the river Spree in Kreuzberg. The area is unique because of its impressive history. During the Cold War it was part of the border between East- and West Berlin. Nowadays it is in the middle of a vibrant and gentriied area. However the site is not accessible to the public.A high dense dwelling house is designed as a vertical Berliner block. A high in-teraction and social mixture between the residents should be achieved.

arkomin - building in Moscow by M. Ginz-burg and I. Milinis 1928-1932

This building embodies an ideal for a society, where the most of the activities are done as a collective.

By ofering Communal facilities such as kitchens, creches and laundry as part of the block, the tenants were encouraged into a more socialist way of life. The structure was thus to act as a social condenser by including a library and gymnasium within it.

This building is characterised by high density with apartments structured over two levels and mini-mised circulation areas.

Analysis

he Berliner Block is very typical for the city of Berlin. It was historically characterised by

its very high density and social diversity. However by bad living conditions too, which were assisted by lack of sun light, humidity and the absence of sanitary facilities. Furthermore a high social hier-archy was present.

Here for this project I would like to maintain the positive aspects of high living density and social di-versity of the Berliner block and modify it so the negative aspects disappear.The Berliner Block should become vertical so that every apartment will have a view over the river Spree and sun light from the South. Through the mixing of diferent sized apartments throughout the building, an access to common gardens and the programmatic design of the staircase a better and closer social life can be achieved.

T

he dwelling program is designed in 7 types of apartments with diferent sizes, combined

in 3 types of blocks. The distribution of the apart-ment sizes is proportional to the demand, so that most of them exhibit a size between 60 and 150 m2 while only few a very small (22 m2) or very large size (210 m2).

The idea of these 3 diferent blocks will elude the typical hierarchy of the Berliner block, and create a mixed social life in the building.

Staircases are visible from outside and diferent kind of small interaction programmes are placed there, especially for children.

The façade of the building is perforated through gaps, making it more transparent and providing green common spaces for the residents.

This temporal installation represents a 3D screen and was built under the park-ing deck behind the main station in Oberhausen. The site was approx. 50 m long and 10 m large. The used materials were scafolding safety net, wood beams and rope for ixing the screens. We were not allowed to present movies from the short ilm festival because of cop-yright reasons, therefore we showed other movies and pictures by a visual artist.

berhausen is a medium big city in the Ruhr area. As a post-industrial city it is shrinking

and sufering from high unemployment. For this we wanted to emphasise one of the posi-tive aspects of this city, the International short ilm festival, and make the people of Oberhausen more aware of it.

We designed a walkable 3D screen, which makes it possible for the visitors to get inside a screen, to become part of a movie, and to experience the dif-ferent scale in its depth.The screen consists of layers with diferent densities and sizes, becoming a labyrinth.

During the design phase we made diferent material experiments to test diferent degrees of translucency.

This project was selected in a competitions with other 5 works out of 40 and has been realised in a larger group in the second part of the semester.The entire project was a cooperation between TU Berlin, the city of Oberhausen and the artist Chris-toph Stark.

uring the realisation phase we had to adapt the project to the actual site, to ind the right

materials and to ind sponsors. We decided to build the screen with scafolding safety net, which we luckily received sponsored. Due to its mesh, this material is partly transparent, so that it is possible to project images onto diferent layers in depth.

We strained the nets under the dock with a rope to the roof and with wood beams on the loor. Within three days the entire installation was built. In the middle of it we built a bar, where we gathered all together at night and showed diferent movies and images on the 3D screens.t

1:1 prototype had to be designed for the park next to the architecture fac-

ulty of the TU Delft. The interactivity of the prototype was from great importance.

Firepark Hyperbody

The site of this project is the „De Vries van Heijstplansoen“ park. Even though it is located directly next to the architec-ture faculty of TU Delft, only few people spend time there. Our goal was to build a path which could be used by the students and the residents from the neighbour-hood for a walk.We developed a prototype whose shape and behaviour can be digitally controlled. Depending on the wind, the structure acts diferently. From a very poriferous structure it can change by wind into a closed and not transparent wall.

fter analysing the site, we came up with two main concepts. The irst one was to main-

tain the intimate atmosphere of the park, and the second one was to activate the park through dis-ruption.

Our concepts of Intimacy and Disruption can be encapsulated through the activity of ire and the resulting creation of spaces. Our design strategy is fueled by the investigation of intimacy and dis-ruption, but also by the inherent logistical issues associated with ire. All our decisions can be relat-ed to these two concurrent design constraints and our understanding/investigation into what it will take to realize our concept.

The intervention will provide answers to the ques-tions of how to integrate ire into an urban land-scape without directly causing bodily harm to users or passersby? and How can ire bridge the gap between disruption and intimacy?”

nvironmental and social aspects:the interaction with the site and the people

around was important for us. For this our inter-vention forms a closed loop system that will cap-ture and re-use waste and materials. It is important that we explore and address the ecological ramiica-tions of the combustion process in order to ensure that is an improvement on the existing situation. Waste materials from the diferent faculties of the

TU Delft can be used as a compost. Through this compost energy for lighting can be produced (gas production in an anaerobic digestor), through the ire ash is produced and it can be used as a nurs-ery in the botanic garden next to the park for plant growth. Through all these activities, we think that the social environment on the site will be improved as well.

Closed loop system

Anaerobic digestor: it is powered by waste food and paper collected from various cafeterias and the faculties of TU Delft. This will create electricity which can be used in systems within the structure.

Wood’s storage: The structure will tap into existing waste lows, for example providing storage space for waste wood from TU Delft, which can then be burnt.

Floor system for ire:A structure will create a space which allows ire to be instigated anywhere along its path, using ma-terial (wood) collected from faculties within TU Delft and stored within our structure.

Shelter position:Our structure will incorporate a movable facade, which can be adapted according to wind speeds: if there is little wind, the structure can be opened, which will also allow light from ires to pass through the structure creating an intimate secondary space.

Wind-stop structure:If the wind speed is too high then the facade facing the wind will close, protecting the ire and the users and providing a usable space.

Waste collection:Waste (ash) produced by ire, will be collected and stored within the loor system, before being used as compost for the plants and garden.

We designed an exhibition house, situat-ed in the southern part of the Friedrich-straße, a diverse and heterogeneous area of Berlin. As a massive volume, it closes the now open block corner, while still providing access to the backyard through entrances on the the sides.The main focus is the interaction of a ro-bust and simple construction with a light facade for the control of the building cli-mate.Here, we want to combine the vault as traditional robust construction with to-day’s modern ways of fabrication.

s a robust construction, the vault has been proven in various ways over the centuries. It

serves as a starting point for our design, where we want to combine these traditional elements with today’s modern ways of construction.

Standardised supporting elements are prefabri-cated in textile formwork, which allows complex three-dimensional shapes. As a material for the formwork we chose a cloth that is commonly used in horticulture because of its high tensile strength.By varying the sewing cut of the textile, diferent formwork shapes can be obtained.

We designed a textile framework for a prefabricat-ed concrete massive pillar. After sewing, it is irst reinforced with glass ibers and illed with 10 cm shotcrete. The inal cast occurs directly on site.

y assembling the prefabricated pillars, a vault construction occurs. On the ground loor they

are distributed following an orthogonal grid, while in the higher loors the number of pillars decreases, in order to reduce the load, thus varying the arch-es spans. The columns are also used as space-dein-ing elements, by embedding rails for mobile walls along the connection lines. This results in a lexible

loor plan for diferent purposes. The massive pillars exhibit a very high thermal mass which allows the building to act as a climate bufer. In summer, the large mass requires a long time to heat, hence cooling the interior. On the oth-er side, the heat collected during the summr permits to warm up the building in winter. In this way the energy consumption of the building can be reduced.

n order to keep the inner concrete structure of the building visible from outside, we designed a

very simple and semi-transparent façade. We sim-ulated the sun light irradiation into the building, and the consequent warming up using the software

Diva. In order to avoid overexposure, we designed a system of lamellae, whose aperture can be con-trolled depending on the intensity of the sun-shin-ing.

* exhibited at “One Architecture Week” 2015 in Plovdiv,

Bulgaria

The intervention is situated at the border between the oldest public park in the city of Soia and the old royal palace (nowa-days national gallery) on the site of the previous Mausoleum of Georgi Dimi-trov. An independent research center should occur here, with the task to inves-tigate, record and present the history of Bulgaria from the communist era. While the research and archive sections are placed underground, the exhibition hall outgrows and is visible from the park. It covers the left bunker of the Mau-soleum and makes it to an archeological part of the exhibition.

o understand the whole issue of this project, a short history review should be done.

For this I provided a booklet, divided in three parts: irst: Overview with the main historical facts from the end of the WWII till nowadays, second: Com-parison between the previous communist countries how they deal with their communist past and the third: A historical, social and urbanistic overview of the site. I listed as well a survey, which I did with 40 people from the city. The diversity and contro-versity of some answers were very helpful and a great source of relection.

Overview

#5 | 04

Main historical events:

On 5th September 1944 the Soviet Union declared war on the Kingdom of Bulgaria. On behalf of the Bulgarian government, the Bulgarian troops of-fered no resistance.

On 9th September 1944, the Bulgarian govern-ment was replaced with the help of the Soviet army and was overthrown by a so called “Home front” (Отечествен Фронт).

During the irst months after the military coup from 9th September 1944, tens of thousands were mistreated without trial or judicial decision, killed or have disappeared (some sources give the number 30 - 40 000).

Between December 1944 and February 1945 a so called “Peoples court” was set down. The conse-quence was: arrested: 28 630; judgements: 10 919; sentence of death 2730; life sentence:1921 ( 1305?)

From 1945 until 1989 many working camps were set up and used to intimidate the population. Thou-sands of people died or have been tortured inside those camps.

Between 1944 and 1989 there was no freedom of speech, no freedom of movement or sexual freedom.

Lots of people were not allowed to study or to work their profession, because they were declared for pub-lic enemies.

During the 70’s and 80’s there was a huge wave of ethnic cleansing of the Turkish minority in Bulgar-ia and thousands of people left the country.

The Communist regime in Bulgaria was one of the most brutal in Europe at that period of time.

assive urban transformations have been repetead in Soia, irst from an Ottoman

to an European city during the end of the 19th and later again during the Communist regime. Now-adays the city of Soia is a mixture of from 19th and 20th century architecture with several “com-munist” structures.

Maybe the most prominent building from the Communist era was the mausoleum of Georgi Dimitrov, the previous Bulgarian dictator. As a very symbolic building it was build within one week in 1949 just on the opposite side of the old royal palace, which was about to be demolished. It was part of the new urban plan for the centre of the city, following a new axis, which replaced the old one oriented to the old palace and the sur-rounding. The upper part of the mausoleum was demolished in 1999, after 10 years of stagnation.

Plan Sofia

he challenge of this project is to ind the right relationship with its very speciic surround-

ing. It is a very complex mixture of controversial history, social science, urban design and landscape architecture.

This relation can only happen, when this project achieves to underline and restore the lost promi-nence of the old palace, reconnect it with the park and at the same time position itself as another im-portant building.

One part of my intervention is set underground, so the park goes through. The entire building fol-lows the old axis givien by the royal palace. This is visible from the museum part of the building, which comes above the ground. This part comes

out only 3 m obove the ground for two reasons:the one is not to break the visible connection be-tween the park and the old palace and the other is, that this is the old level of the ground before the urban changes from the 50s. In this case, being on the top of the building it will be possible to see the old perspective of the place. The top of the building should be used as a public space, an extension of the park used for concerts, skateboarders or just for observation.

The new intervention shows the mausoleum as an archaeology, however the building appears closed to the public. Through an opening on the top roof and from the side windows you can only assume what it is inside making you curious to enter the building.

From the foyer it is possible to directly see the archives, one of the signiicant parts of the building, where all the memory is kept in. The entrance to the museum hall occurs from one of its corners, in order to pro-

vide the visitor an oveview of its dimensions and relationship with the mausoleum ruins, which is made accessible for the public. Through it the mu-seum is divided into four spaces. To underline the relationship between the mausoleum and the mu-seum, the exhibition is going to be presented only on the external sidewalls and in glass cabinets for diferent artefacts.

he idea of reusing things is of a big interest to me. The transformation of objects from old

and “worthless” to something new and useful is for me exciting. In this case an old wooden window frame from

Saxony, more than 150 years old, was reused to be-come a book shelf. The window is ixed to the wall at seven points with 15 cm long wooden baulks. Small wooden bars have been applied on the wall to keep the books upright.
