The building is primarily a board-shaped (nod to modesty), poured-in-place concrete, which appears as an extension of the rot-granite soil. Clads side nonbearing mahogany walls. The roof is a mahogany-and-steel-faced concrete supported by steel columns exposed, and one on the interior steel columns on each exterior (echoing the verticality pine trees). Floor to ceiling glass walls set a whole, and defining, indoor-outdoor character.
