Pine Flat Residence: Home and Forest in Dialogue

Northeast of Healdsburg, California, a winding former stagecoach road climbs into the Mayacamas Mountains. It leads not only to a home but to a way of life that is remote, self-sufficient, and deeply anchored in the landscape. With the home on the former site of Pine Flat – a community that flourished during the 19th-century cinnabar rush – Faulkner Architects needed to focus on both local history and the escalating wildfire risk.

Pine Flat Residence: Inhabiting history

An earlier off-grid home that was destroyed in the 2019 Kincade Fire was the starting point for a radical rethinking of contemporary living in wildfire-prone settings. Faulkner Architects developed a program that focused on durability and resilience. The home’s Cor-Ten steel shell is resistant to fire and weather. It works in conjunction with sliding ember screens and outdoor sprinklers that protect the terraces. Every building choice centered on improving fire resilience.

The project reuses the foundations and walls of the former house. Representing 90% of the completed building’s concrete, the approach preserved embodied energy and minimized additional excavation. The new rectangular volume sits on the existing angled foundation and plinth. The plinth, half-buried in the slope, contrasts with the raised volume. Its simple shedlike structure follows the site unobtrusively, as if it has always belonged here.

The design emphasizes accessibility. An entry ramp, clearances for wheelchairs, provision for an elevator, and the location of the main bedroom on the same level as the living area all reflect a house planned for the clients’ needs.

Living with the landscape

The mass of the new concrete fireplace anchors the main floor and frames the hearth as a focal element against the landscape. A model of passive resilience, the off-grid system comprises an upgraded photovoltaic array, full rainwater capture, vegetated bioretention systems, and storage basins that double as wildfire water reserves. Spring-fed wells supply all water needs, including a dedicated tank for the hydrant and sprinkler system. A concrete basin collects water after it has passed through a Pelton turbine for supplemental hydroelectric power, while the repaired septic field manages wastewater.

In an era when residential development continues to encroach on natural landscapes, Pine Flat Residence demonstrates that residential architecture can – and must – move beyond trying to control nature and learn to coexist with it.
