REGULAR HOUSE

Single Family Residential Passive House
New Construction
1,800 SF
Philadelphia, PA

Regular House developed from the owners’ desire for a home that prioritized long term resiliency, comfort and Zero Energy construction.  Using the Passive House (PHIUS) system as a template to achieve their goals, the architectural team looked to complement the certification program’s clinical rigor by reducing design complexity: Regular House utilizes a stacked structural system without offsets or protrusions, one exterior building material and a single window type.  The resulting design uses color and pattern to break the house into two tiers: cap and base- marrying visual sophistication with compositional restraint, down-to-earth building science, and attention to embodied (material) carbon.
