Woodlake House is on a site in the oak woodlands of western Nevada County, looking out over a quiet community pond, in a rural development. The land was purchased in the 1970s by our client’s late husband but never built upon—an intention suspended in time. When our client asked us to design and build here, the directive was both tender and forward-looking: complete a vision that had been held for half a century, and create a home meant not specifically for her but for future others. A legacy project, expressed as an investment in the long arc rather than the immediate return.
The parcel is bordered by neighbors and crossed by a shared-use road at its entry. In response, the house is oriented with care on the rocky site, stretching out in a linear form so that each room connects to the more private portion of the property with a view of the pond. The front façade is organized as a welcoming greeting meant to draw one into the house and provide a “peak” of what is hidden behind the house. The breezeway, between house and garage, provides a sightline to the pond as one approaches the building while offering connection to the essential utility spaces—laundry, mudroom, mechanical room, and a half bath—keeping the rhythms of living practical and unencumbered.
We approached the design as an intermingling of memory and prospect—conclusion and activation. Our client wanted to create a house that was grounded on the site, built with craft and care, that was adaptable for whomever lived in it. With the idea of flexible, easy living as our guide, we concentrated the primary footprint on the main level (to allow aging in place). A single, light-filled living space that gathers the kitchen, dining, and sitting areas opens to a large, covered patio to allow for easy flow from inside to outside. A simple color palette and durable finishes were selected with longevity in mind.
Throughout the design process, the brief remained consistent: create a home that belongs to its site, that supports healthy, comfortable living, and that reflects our best practices in performance and durability. Clad in a mix of cementitious and metal siding, the building is intentionally robust—low-maintenance, fire-resistant, and prepared for the realities of the California foothill region.
Opting to build a high-performance home for an investment property may seem unconventional, but here it aligned with the project’s deeper purpose. The ROI was never meant to be short-term or transactional. Instead, the value lies in resilience—reduced operating costs, improved comfort, long-term durability, and the ability to offer future generations a home that performs well while treading lightly. In this way, Woodlake House becomes a different kind of legacy: one rooted as much in responsibility as in remembrance.
High Performance Highlights
Assembly
In the hot dry climate, where this home is located, air-tight construction provides the most effect energy savings and building comfort. The Woodlake house reaches high levels of air tightness, testing out at .04 CFM50 per sf, which was achieved by attentive construction and proper installation of triple pane fiberglass windows. The roof is an unvented assembly to provide better wildfire resistance and the concrete slab is insulated for comfort.
Climate Control
A balanced heat-recovery ventilation system (HRV) ensures constant fresh, filtered air, throughout the home without any substantial heat loss. Indoor climate control is provided by a ducted mini-split system.
Energy
A 5.04kW rooftop PV system and 15kWh backup battery system provides renewable energy for the home and offers resiliency during grid power outages. The all-electric house includes an induction cooktop, heat pump water heater, and car chargers in the garage.
