ZERO SIX
Multi-Family Residential
New Construction
14,760 SF
Philadelphia: Allegheny West
This development is comprised of six single-family townhomes a short stroll from Philadelphia’s Laurel Hill Cemetery. Grounded by a red brick base with slate cladding above, these homes borrow elements from their historic surroundings while positing a climate change adapted future. A three-story mansard roof distorts one’s perception of height as floor locations are blurred. These townhomes front a narrow, human-scaled woonerf, or living street, bereft of curbs, rife with plantings, and paved with the reclaimed brick of past structures on site. Each home within the Zero Six development has been modeled to achieve Net Zero Energy with a planned rooftop solar photovoltaic canopy.
