The metal supporting system of the house follows a strict grid which optimizes time and budget saving. The grid also generates the composition of the various spaces and areas of the house both indoors as well as outdoors. Sliding elements on the ground floor regulate the relationship of the spaces in the interior (separate rooms or open plan) as well as the boundaries of the interior with the garden giving the chance sometimes to open up the house completely towards the landscape or some other times close it completely and include also part of the garden!
