Built in Izabelin, a rural Polish municipality in the district of West Warsaw, and hidden in the forest, Circle Wood's shape and colours recall a section of a tree trunk. In fact, this was the intention of Polish architectural practice Przemek Olczyk Mobius Architekci, which built the project for a private client. Circle Wood was built with the aim of creating a home in contact with nature and without spoiling the landscape.The home, which has a circular layout and a surface area of 400 square metres on two levels, is built of reinforced concrete covered on the outside with a special type of wood from West Africa, Okume wood. This material was chosen both for its colour, which matches that of the forest, and for the low number of knots in the wood, which makes the house's outer surface more uniform. At the ground floor the house has a garage, a spa area and an inner courtyard that allows full use of natural light and still has some pine trees, giving the feeling that the forest has grown all around the house and creating a sense of continuity between inside and out. The interior spaces have been designed in such a way as to separate public and private areas, but each room has large windows overlooking the greenery. A characteristic element is the staircase leading to the upper floor, with its clean, sinuous lines. In terms of interior design, the house was conceived as a sort of art gallery for the client's private collection.
