The basic architectural design, a glass box surrounded by a walkway-gallery that connects the floors, was designed before the land was found.  The basic design include from the beginning all the aspects of the project, from the shape of the building to the design of light switches and furnitures. Usually an architecture projects is developped sequencely, building, interior furnitures, products, making it is difficult to be totally homogenous.

To achieve a weighless architectural space we use 25mm steel slabs as floor. This is equivalent to a line in the architectural scale. The scale of furniture and architecture become the same. From the slope, the interior is visible from floor level to ceiling level the top of a table is as visible as the buttom, a real 3d interior, a very difficult challenge. Using 3d animations and models the sequences of the interior were checked from all angles. c-1 is not a minimalist house on the contrary, it is expressionnism.
