This new residential building is located in a unique location near Collserola, where the small scale of the neighbouring domestic buildings is mixed with teaching or care facilities of a larger entity. The proposal seeks an implementation scale appropriate to the environment, complementing the domesticity of the single-family residential fabric with the greater dimension and scale of other pieces in its environment.
An L-shaped building aligned to the streets and open to the good orientation and views is proposed, where most of the houses face south or south-east.
The volume of the building is compact towards the street, with a north façade where the access corridors to the homes are arranged and an energy filter is generated. On the other side, it breaks down and steps towards the interior of the lot, making the contact with the neighbouring courtyards more domestic. The main access is located at an intermediate level that brings the building closer to Quatre Camins Street.
The adaptation to the topography allows the creation of two large community spaces, where the elderly can carry out outdoor activities. The first, located on the first floor, is a terrace in direct relation to the garden space and the other, on the third floor, connects to the laundry and the deck.
All the homes have a comfortable space that connects them to the outside, in order to obtain better protection against the wind and privacy from the neighbours. In addition, the ceramic lattices and adjustable blinds work as temperature modulators and are a passive energy saving measure that increases user comfort.
In general, a construction with minimal ecological footprint and low energy demand, compact and with good thermal insulation is proposed. The use of solar radiation and mechanical ventilation with heat recovery, following PassivHaus standards, allows a 75% reduction in total consumption, and an A energy rating.
