ECONOMIC SUSTAINABILITY | SOSTENIBILITÀ ECONOMICA

The costs of construction are about 30% lower than comparable free-financed projects, but the most important issue is the providing of land for  subsidized housing projects, which is managed by the Land Advisory Board. As a winner of the public property development competition the  developer was able to buy the site less than one tenth that of usual costs!

Rental/sale cost compared to market price
Costo di affitto/ vendita rispetto al mercato:
The project is a successful example of individual, affordable and high-quality housing in ownership in view of the current market situation in Berlin’s housing sector. 51 tailor-made residential floor plans could be realized in individual design.

SOCIAL SUSTAINABILITY – SOSTENIBILITÀ SOCIALE
Rules of allocation – Regole di assegnazione:
No

Protection of fragile categories
Tutela categorie fragili:
Yes, single parents such as mothers.

Involvement of inhabitants in the building process – Coinvolgimento degli abitanti nel processo:  The simple structure of the buildings leaves plenty of leeway for residents to design the spaces themselves before moving in, and also provides the opportunity to adjust the apartments to changing uses and needs later on.

Community accompaniment in the life of the building – Accompagnamento della comunità nella vita dell’edificio: 
No.

ENVIRONMENTAL SUSTAINABILITY
SOSTENIBILITÀ AMBIENTALE:
Functional mixitè – Mix funzionale
The complex stands on a site previously occupied by a freestanding supermarket, which has been seamlessly integrated into the ground floor of the building facing the street. Also integrated in the ensemble of buildings there is one guest apartment.

Common spaces and shared living – Spazi comuni e abitare condiviso:
A communal courtyard has been placed on the roof of the ground-floor supermarket. On both sides of the garden houses, four smaller courtyards are created along the borders with the surrounding properties.

ENVIRONMENTAL SUSTAINABILITY
SOSTENIBILITÀ AMBIENTALE
Techniques and strategies for environmental saving: 
Despite its high compatibility of 4 different buildings and a previously freestanding supermarket the project offers new ecosystems to grow by arranging 4 courtyards and an urban garden with large green areas in the middle of the city.

Description of the project:

Our reflection is about the search of new qualities in housing, that develop in the interaction between individual and collective. It’s about combinating qualities of individual housing with the efficiency and sustainability of collective housing. Therefore, we propose to associate in a single operation very different typologies : individual and crossing houses with terrace and small garden in street front, reversed duplex with access from corridor and loggia open to the sky, attic duplex with large terrace, panoramic housing.

 

The project searches to create conditions that favor the emergence of a great typological diversity, in order to answers to the different inhabitants’ wishes, and to give a wealth and complexity to the scale of the block.

 

An important point of our project is to have mixed social and free sector housing in the same building. Moreover, they have been distributed randomly in the building so that everyone can cohabit and interact freely. Indeed, the project is aimed at all types of families. The residents of the mixed program have different living standards but the same quality of life highlighted by the different typologies of units.

 

The 53 dwellings are distributed into two builgings, with 68 parking spaces semi-buried. The project develops a volumetry formed by a 3-levels base on which two volumes of two levels in attic are placed, composed exclusivly of duplex housing. The center courtyard is a natural space, mostly planted in burial and surrounded by a deck forming the semi-buried parking’s roof. Pathways integrated into the garden allow to cross the courtyard from the north to the south and to distribute all the intermediate housing with a serie of footbridges above the embankment.
