Single Family Residential
New Construction
1,900 SF
Philadelphia: Kensington

This single-family, eight-level rowhome tucks neatly into the eclectic fabric of Philadelphia’s architecture. By altering the traditional rowhome model to become multi-leveled, the architect maximizes space for living. While it appears small from the street, once inside, high ceilings and ample glazing provide visual continuity while a stair-core physically connects all levels. To juxtapose the dynamic interior, the front facade is purposefully quiet. It is clad in a single material and is devoid of the utility equipment that typically clutters urban projects. Even the systems are reduced to a single source, electricity. It represents a version of what all urban infill homes can be.
