Zero Six


Multi-Family Residential
New Construction
14,760 SF
Philadelphia, PA: 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 and 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. A solar array allows the Zero Six to obtain zero energy.
