Vienna, „Bikes and Rails“: Cohousing Project

313

Project 313

Wohnbau Bikes & Rails, Vienna by Arch. Georg Reinberg, Vienna, Austria.

The project was realized within the framework of subsidized social housing. It is part of a new urban development concept (Sonnwendviertel Ost) whose urban development concept was developed in a cooperative process. All parking spaces are on the outskirts of the district (between the railway facilities and the residential buildings) and the main access road is free of traffic.

In the architecture competition, plots of land were kept free for cohousing projects and assemblies to which the architect could apply. The submitted competition entries were assessed not only according to the usual criteria of economy, ecology, social sustainability, and architecture but also according to how much the modules could contribute to the revitalization of the district. In the given case, these are a bicycle cafe, common rooms, and the revitalization of the district through an access area completely glazed to the urban area (which also serves for passive use of the sun).

According to the special location of the building, the south facade opens up to the sun and the urban area, the west facade has generous windows in the direction of Helmut Zilk Park and the north facade remains relatively closed with window openings that provide a visual view of the green space.

The ground floor is transparent and provides space to complement the public areas in the form of a covered terrace (in the west) and a covered outdoor area (like an arcade) in the south. There is a bicycle café and a bicycle workshop as well as a common room.

A southern veranda is used for communication with the public space, for access, and as a communal area with private loggias.

The basement, the ground floor, and the southern veranda are made of concrete, the living areas are made of wood (ceilings and central wall: cross-laminated timber panels, outer walls: wooden frame construction).

There is a communal roof terrace on the roof. Bicycles can be parked in the garden in the basement. There are also storage rooms in the basement.

The building concept was developed in a joint process and the apartments are also planned individually.

The house is designed as a passive house.

TECHNICAL SPECIALTY

The living area is constructed entirely of wood (5 floors, wooden stud walls, and cross-cut wooden ceilings). This living area is placed on the ground floor and connected to the concrete structure of the winter garden. The ventilation takes place via two central ventilation systems with heat recovery, the air distribution takes place via vertical shafts.

ECONOMICALLY

The realization takes place within the tight financial framework of the Vienna housing subsidy. The project is part and the first project of habiTAT – the apartment block syndicate in Austria. The habiTAT is solidarity of house project initiatives all over Austria with the aim to buy real estate freely and to secure self-administered and affordable spaces. In this context, money was collected through direct lending (crowd leaning) and it can also be made available to residents who have no saved funds.
