Description of the project:
These 18 subsidized housing address the transition between a block of row housing and a series of single-family homes, and exploit the conditions of their own site that follows a slight gradient, sloping from the street inwards. The surrounding conditions call for a building that extends lengthways but also allows the dwellings to face south rather than directly overlooking the neighbouring buildings.
The conditioning factors suggested the solution of six dwellings per floor on three levels. They are grouped around two communication shafts, each of which leads to three dwellings per landing. The dwellings adopt what is almost a single model for all 18 apartments. They are L-shaped with all rooms airing directly to the exterior. They overlap so that all the living rooms have openings that face south-east and south-west, ensuring sufficient daylight, even in mid-winter.
To regulate the amount of sunlight received, the south-west façade has metal slat blinds. In the south-east, projections provide a shield from the sun in summer but let it in during the winter. For optimum ventilation, an inner courtyard runs right through the block beside the stairwell and acts like a great chimney which improves the temperature conditions of the dwellings.
On the roof, there are solar collectors for the production of domestic hot water using renewable energy. On the basement floor, there is a space for selective waste sorting.
To keep the building affordable and easy to maintain, it uses as few materials as possible. They are moreover cheap and easily available. Façades are in single layer mortar and internal partitioning walls in plasterboard.
The layout of the complex guarantees the privacy of the dwellings and avoids direct confrontation with the neighbouring single-family dwellings.
For greater ease of access, each of the communication shafts includes a lift and is designed for ease of movement for people with reduced mobility. Since some of the residents will be elderly people, it seems appropriate to give their living rooms access to terraces where they can sit and enjoy their own landscaped space.
The corridor in the apartments is kept short and laid out in such a way that there is a space at the entrance with turning space for a wheelchair. The bathrooms, in which the shower is on the same level as the floor, are also practicable for people with reduced mobility.
