Our office was asked to transform and expand a 1980’s-era attached duplex into 2 houses, or condominiums. We added 2nd-story master bedrooms to the front of the houses with new living areas below, and thus redefined the massing of the houses, their entrances, and sense of autonomy vis-a-vis each other. We played with the line between sameness and differentness of the units of this former duplex: we underscored that they are two mirror-imaging units of one larger structure, yet at moments treated the fronts of each slightly differently, imparting to each homeowner a sense of uniqueness. At the existing structure, we broke into the attic area to gain space for the lower level kitchen, exposing the original fir truss members and adding light from above. For the skin and character of the addition, we composed a composition of cladding: thin vertical brick and polygal insulated translucent wall panels. Our material choices, and approach to the treatment of the existing structure were in part born from the challenges of the developer’s limited budget.
