The static typology of an existing 8 story office building was transformed into a more dynamic one through its expansion into a 156 unit, 13 story apartment complex that widens at its center and gently narrows to accommodate views and increase developable area. Along the façade, horizontal bands of fiber cement panels thicken at the center and narrow near the edges to create a variety of naturally lit bright spaces. These bands are broken up at the edges of the new addition by alternating loft apartments which offer double height glass spaces. The inherit interior architecture of these lofts create an exterior architectural language. The sloped roof line follows the profile of the topography and serves to hide the mechanical spaces and elevator penthouse.
