This single family home per SB-9 & ADU project embraces California's forward-thinking regulations to combat the housing shortage in Los Angeles by introducing additional residential units. Designed to meet the rigorous International Passive House Standard, it ensures superior energy efficiency, exceptional comfort, and outstanding indoor air quality.

2026 the projecy was an AIA|LA Residential Architecture Awards Winner by the American Institute of Architects Los Angeles (AIA)- The Climate Positive Award for the Certified Passive House | Small-Scale Density, Big Performance: SB9, ADU & EnerPHit Retrofit. The jury noted “A highly intentional sustainability project that integrates rigorous high-performance standards from the outset while retaining portions of the existing structure to reduce embodied carbon. Through Passive House strategies, solar generation, airtight construction, and advanced filtration systems, the project demonstrates how small-scale density can achieve exceptional environmental performance.”

The International Passive House Standard represents a globally recognized benchmark for energy-efficient building design. It focuses on principles like airtight construction, high-performance insulation, thermal bridge-free design, optimized ventilation with heat recovery, and the use of high-quality windows. These elements combine to create homes that are not only energy-efficient but also provide unparalleled comfort, reduced utility costs, a smaller environmental footprint, and enhanced acoustic performance.
