Our objectives are to demonstrate energy efficiency that is applicable and affordable to single family homes. The project includes series of prototypes that can be combined to obtain the desired living space. Elements in the interior allow reconfiguration of space to allow it to adjust to changing living styles. 
Emphasis is on ecological building materials, conservation of natural resources and the use of renewable energy sources. The concept of the houses "Septagon" underlies sustainable and environmentally friendly way of life of their inhabitants.
