Sonoma weeHouse We're in touch

Alchemy Architects (Geoffrey Warner) · Sonoma County, CA · ~970 sqft · two modules (640 + 330 sqft)
Sonoma weeHouse glimpsed through gnarled oaks on golden grass

The client here is an architect himself and Apple's Senior Design Director responsible for Apple Stores worldwide — he co-piloted the design with Geoffrey Warner, Alchemy's principal. The result is two minimalist, open-sided boxes set on horizontally banded, board-formed concrete plinths, nestled on the edge of gnarled oaks — almost exactly our own siting.

It's two modules: a 640 sqft main house (a centered whitewashed-oak bed platform, with kitchen-dining-living on one side and bath on the other) and a separate 330 sqft guest house. Steel frames, nine-foot sliding glass walls, ipe interiors and oiled-oak cabinetry; a dramatic 10×40 ft porch module cantilevers into the landscape. Built in Oregon and shipped 90% complete to Santa Rosa. Awards include the 2018 AIA National Small Projects Award and a 2019 Dezeen Award.

Why it fits

Cost

Estimated all-in
~$500–700K for this custom build (est.)

No public figure for this one-off — the board-formed plinths, custom steel and ipe make it a high-spec build. Alchemy's catalog prefab line is published (modules only; add ~$50–150K site work, and they run "10–15% less than conventional"):

1X — $79K · 435 sf (~$182/sf) 2X "Pair" — $185K · 1,450 sf (~$128/sf) 3X — $175K · 1,335 sf (~$131/sf) 4X — $250K · 1,765 sf (~$142/sf)
