Custom Guest Houses That Feel Inevitable
Bespoke, standalone guest houses designed as cohesive architectural extensions of luxury wine-country estates in Healdsburg and Sonoma County.
Schedule ConsultationArchitecture, Not Afterthought
Your estate has a story. A relationship between the main residence, landscape, and materials that took years—sometimes generations—to establish.
A guest house shouldn't disrupt that story. It should feel like it was always part of the original vision—a natural extension of your property's architectural language.
That's what we do. Ground-up custom guest houses that complement your estate's existing architecture, materials, and landscape character.
