This is the comp that maps most directly onto our project: an off-grid straw-bale home in rural Sonoma County, on a large creekside property. The plan is a series of east–west running volumes that roughly parallel the topography and step up the hill — exactly the move our sloped north pad invites.
The build combines highly insulating straw-bale walls with lime plaster, earth-masonry retaining walls, and sustainably harvested timber, with living roofs and corrugated metal that reference old agrarian structures while blending into the landscape. South-facing glazing pulls daylight deep into the living spaces, and the whole thing is organized around indoor/outdoor flow with terraces and a roof deck.
No public figure. As a large, high-spec, off-grid custom straw-bale estate by a sought-after firm, it sits well above catalog prefab — our estimate reflects comparable Sonoma natural-build estates. Useful as the upper-bound, fully-custom end of the spectrum next to our ~$1.8–2.2M two-ADU budget.
