Three Arizona firms were invited to prepare a multi-family housing proposal for an iconic concrete structure near the Camelback corridor. The existing single-level office building was a classic example of the lifted modern office prototype floating on laterally stabile pilotis with shaded parking underneath. An open sky court provided light, air, and entry up into the center of the building. Proposals were asked to build upon the post-tensioned concrete structure as it was originally calculated to accommodate two additional levels of office space. Our proposal differentiated itself first by preserving the timeless benefits of this classic typology, specifically the shaded and well-ventilated ground floor for auto-pedestrian flows. Secondly, it promoted a variety of unit types: generous free-plan single story terrace units between the existing slabs with two-story townhouses above. The exterior edges were configured to promote indoor/outdoor living spaces with private-panoramic-views of the valley’s north and south mountains with the downtown Phoenix city lights, while shielding all from the harshest east-northeast/west-northwest Arizona sun.
