The board-formed concrete is sovereign on the residence. Made in an experimental way by the construction team, the client approved the quality of a wall prototype made in the beginning of the construction, being adopted later as coating for the whole house: walls, ceiling, flooring, all elements apparent and definitive.

It is ready as soon as it is unmold.
