New Passive House in ThE foothills
Initial Concept Sketch
Mass Timber Passive House
A collaboration between HSS Design Build, Stitch Consulting and Design , and our wonderful clients.
This custom home showcases what’s possible when thoughtful design meets high-performance construction. From the outset, our clients have been committed to building a residence that prioritizes sustainability, energy efficiency, and long-term resilience.
Designed to meet the rigorous Passive House Classic standard, the home offers exceptional comfort, outstanding indoor air quality, and significantly reduced energy consumption year-round.
A key feature is the prefabricated mass timber building shell, which allows for greater precision, faster on-site assembly, and reduced construction waste—crucial for meeting Passive House performance targets.
The extensive use of renewable, wood-based products was a deliberate choice, driven in part by their ability to sequester carbon throughout the building’s lifespan. The building envelope includes wood fiber insulation, a breathable, high-performance material that supports thermal efficiency. Inside, exposed cross-laminated timber (CLT) provides structural strength, and visual warmth. Untreated wood surfaces further enhance comfort by naturally regulating indoor humidity through the absorption and release of moisture.
European triple-glazed windows minimize heat loss, reduce solar gain in the summer, and eliminate drafts—while offering acoustic comfort, durability, and clean, modern detailing that complements the architecture.
The home also features high-efficiency mechanical ventilation with heat recovery, delivering continuous fresh air while retaining heat—boosting both energy performance and occupant well-being.
Scandinavian-inspired design and simple lines help reduce thermal bridging and improve performance. Rooftop solar panels help the home achieve net-zero energy use while reducing its environmental impact.
This project is a testament to our belief that timeless design, environmental responsibility, and advanced building performance go hand in hand.
