Multi-Family Residential (Attached Townhomes)
New Construction
19,300 SF
Philadelphia: Fishtown

This development comprises eight single-family homes composed as a series of shifting cubic volumes. Site constraints eliminated the potential for rear yards, creating an opportunity to incorporate outdoor space elsewhere. The design steps back from the street-facing edge to establish courtyards in front of each unit. Here, an undulating brick wall wraps the property as an amalgamation of the stoops and porches that fill the neighborhood. This open space works in unison with the vacant lot across the site to create a communal and expanded ‘front yard.’
