Construction began after June 1st, ensuring completion of an enclosed shell by October 1st, during the region's dry period, to maintain mold-free building materials. The foundation, a raft slab monolithic single pour system, laid the groundwork for the residence. Assembly of wall panels, structural framing, and roof panels was accomplished in just 2-3 weeks using a crane.

The interior boasts "parlant Architecture," showcasing exposed structural members to highlight their purpose. A meticulously designed utility chase routes electrical feeds, ductwork, propane gas lines, and plumbing throughout the house and ADU. Extended overhangs provide dry access around the home during the rainy period from October to June. Transom windows on the South, East, and West walls enhance natural daylight.

Energy Efficiency and HVAC:

HERS Testing: Not completed yet; initial blower door test resulted in less than 0.5 ACH.

HVAC System: Minotair PentaCare V12 Compact Air Treatment Unit with balanced fresh air HRV, certified by HVI. Two individual units serve the residence and ADU.

Additional features include below slab and footings insulated with 6” high-density EPS type XIV (R-25.2), Alpen windows (R 7), doors (R 5.88), and sliders (R 6.25). The house is equipped with all LED lighting, SANCO2 heat pump water heater, and heat pump dryers by Whirlpool and Miele. The roof is solar-ready for a 6KW solar array.

Design Details: The foundation is wrapped in 4” high-density EPS transitioning to a Cor-A-Vent siding system, wrapped/flashed with custom-fabricated stainless steel. Interior slabs are epoxy-coated and exposed for maximum energy transfer. Window sills feature live edge redwood from locally harvested trees, and stained glass repurposed from a local recycling facility adorns the entry door transom.

The rain screen siding system, made of red cedar clapboard with a 4” exposure, is primed and finish-coated on Cor-A-Vent plastic furring system, vented at the top and bottom, and is projected to last 30 years without repainting. Landscaping features include plant materials installed by the owner using “Good Earth” amended soil.

This residence and ADU exemplify the anticipated construction and energy code requirements for 2050, setting a new standard in sustainable living.
