Quadrant House is an innovative project developed by the KWK Promes architecture agency led by Robert Konieczny in Poland.
Quadrant House is inspired by geometric devices commonly used by astronauts that help map out
the position of stars. The house, therefore, features a piece of kinetic architecture that tracks the
sun’s movement and adjusts to it: a moving outdoor living space pivots and docks with rooms on
both sides of the garden, offering them an open-air extension.
Even though the idea may seem very complicated, the execution is quite simple: hinges and rails are
used so that the moving terrace can rotate 90 degrees. The system that moves the platform is fully
automated, but can also be controlled manually. The scheme, hence, reacts to the sun’s movement
while ensuring shade and ventilation for those inside the house.
The design incorporates two main volumes: a single storey structure that runs parallel to the road, perpendicularly connected to a two storey section containing the home’s primary functions. The form of the house is a response to both the client’s wishes and local building regulations: the design presents a gable roof to the passing streets. However, the shape changes as it progresses towards the back of the plot, giving the impression of a flat-roofed structure from the garden—something the client was very keen on.
Even if the exterior and interior aspects of the house display a sense of simplicity and minimalism,
many may consider the rotating terrace to be contradictory to minimal design principles.
