Sustainable house on Lake Laka in Poland 

This sustainable house – like a chameleon – blends with its surrounding area on Laka Lake in Upper Silesia. Colourful planks within the timber façade reflect the tones of the landscape. The window reveals, clad in fibre cement, frame images of the countryside. Analogical to the most creatures, the building is outside symmetrical, although the internal zones are arranged asymmetrically according to function

The built form is designed to optimise the absorbance of solar energy. Approximately 80% of the building envelope facing south. The single storey living space on the ground floor is externally clad with untreated larch boarding. Solar energy is gained there by the set-in glazed patio. Solar collection panels are located on the roof and a photovoltaic system is planed for the future. The dark facade of the “black box” - a three storey structure clad with charcoal coloured fibre cement panels - is warmed by the sun, reducing heat loss to the environment. The passive and active solar energy concepts and a high standard of thermal insulation are enhanced by a ventilation plant with thermal recovery system.

The design of the project was determinated by the twin goals of low lifecycle costs and a reduction in construction costs. All details are simple, but well thought out. The house did not cost more than a conventional one in Poland. Cost-saving were made by the application of traditional building techniques and the use of local materials and recycled building elements.
