Powerhouse carefully fits a dense cluster of 31 super-energy-efficient units into an urban block in Philadelphia.
Powerhouse carefully fits a dense cluster of 31 super-energy-efficient units into an urban block in Philadelphia. The design navigates existing fabric along a sloping site with a series of building typologies including single family townhomes, duplexes, and two small apartment buildings. A wide variety of unit types provide diversity of living options in keeping with the character of the surrounding community, and at a range of prices to meet the needs and budgets of residents. Expanding on the Philadelphia tradition of entry stoops acting as mediators between public sidewalks and private residences, a sequence of generous entry platforms navigate grade changes, entry stairs, and basement windows, with fabricated handrails designed by a local artist. Stormwater is completely managed onsite with green roofs and rain gardens along the curb line. The buildings are super energy efficient, with all 31 units achieving LEED Platinum certification.
