Zamora Offices by Alberto Campo Baeza Within the stone box, a glass box, only glass. Like a greenhouse. With a double facade similar to a Trombe wall. The external skin of the facade is made of glass, each single sheet measuring 600x300x1,2 and all joined together simply with structural silicone and hardly anything else. As if entirely made of air. The trihedral upper angles of the box are made completely with glass, thus even further accentuating the effect of transparency.
