Safe House by KWK Promes

Safe House

Warsaw, Poland

Set in a small village in the outskirts of Warsaw, Poland, is Safe House, a unique home designed by Robert Konieczny of Polish architectural firm KWK Promes.  The clients’ top priority was to gain the feeling of maximum security in their future house, which determined the building’s outlook and performance.  The house took the form of a cuboid in which parts of the exterior walls are movable.  When the house opens up to the garden, eastern and western side walls move towards the exterior fence creating a courtyard.  After crossing the gate one has to wait in this safety zone before being let inside the house. In the same time, there is no risk of children escaping to the street area in an uncontrolled way while playing in the garden.


The innovation of this idea consists in the interference of the movable walls with the urban structure of the plot.  Consequently, when the house is closed (at night for example) the safe zone is limited to the house’s outline.  In the daytime, as a result of the walls opening, it extends to the garden surrounding the house.  The sliding walls are not dependent on the form of the building.  That is why this patent can be applied to both modern and traditional, single- and multi – storeyed houses covered with roofs of different geometry.  This universal solution we came up with gives a new type of building where not the form but the way of functioning is the most important.  The name: “safe house” gains a new meaning now.

Once the house opens, it’s bright and spacious interior merges extensively with the garden.  Wide glazings behind the movable walls let the building acquire energy during the day (winter) or prevent the sun’s heat from going into the house (summer).  At night, when the house is closed, the thick outer layer helps the building to accumulate the gained energy.

Such a solution together with the hybrid heat system (most of the energy is gained from renewable sources — heat pump and solar systems supported with gas heating) and mechanical ventilation with heat recovery makes the house become an intelligent passive building.  Every day the house acts in a similar way — it wakes up every morning to close up after the dusk. This routine reminds of the processes occurring in nature — the house resembles a plant in its day and night cycle.
