A High-Performance Passive House Retrofit (EnerPHit) in Lakewood
Experience a new standard of comfort, air quality, and acoustic performance in this reimagined four-bedroom, two-bathroom residence in Lakewood's vibrant Gateway neighborhood. Designed and engineered to the International Passive House standard, the home moves far beyond conventional renovation, offering a high-performance living environment built on precision, durability, and quiet craftsmanship.
Natural light moves freely through the home, drawn upward by soaring ceilings that open the interior into a bright, airy, and effortlessly comfortable space.
Inside, the experience is defined by stillness, a whisper-quiet interior with consistently superior air quality. A high-efficiency energy recovery ventilator (ERV) with MERV-13 filtration continuously delivers fresh, filtered air throughout the living spaces, day and night.
An airtight building envelope, premium European-style tilt-and-turn windows, and advanced thermal insulation work in concert to hold a stable, comfortable indoor climate through every season, while a state-of-the-art heat pump system manages temperature with quiet precision.
Fully electric throughout, the home is equipped with a CO₂-refrigerant heat pump water heater for minimal environmental impact, an induction cooktop for clean and responsive cooking, and a ventless heat pump dryer — a residence engineered as thoughtfully behind the walls as it is designed within them.
