architecture-design · 2026-08-11

In Mendocino, California, Nadia Oka and Michael Topolovac have developed a retreat spanning 2,025 square feet on a 53-acre site, crafted by Jensen Architects from San Francisco, under the direction of Mark Jensen. This residence, perched on a hilltop at the northwest boundary of the Russian River watershed, includes two bedrooms and two-and-a-half bathrooms. Michael, a skilled product designer, established a welding shop on the premises to create bespoke windows and doors. The design draws inspiration from Jay Appleton's 'prospect-refuge' theory, emphasizing sustainability and fire safety through the use of non-combustible materials and solar energy. Michael advocates for a 'life-of-the-house solution' in terms of materials and design, aiming for enduring value.
