The reBuild Approach

Architects, interior designers, and builders work as one team from the first sketch. Real construction costs shape the design early, so decisions are informed and the design reaches the finished house intact.


How we work→

One, Architect-Led Team

Airtight envelopes, filtered fresh air, and all-electric systems make our houses quieter, healthier, and far cheaper to run. At Windsor House, rooftop solar generates 90.6% of the home’s annual electricity, bringing it close to net zero.

Healthy, High-Performance Homes

We restore what makes an old house worth keeping, from ornamental plaster and fretwork to paneled stairs and parquet, and design contemporary architecture and interiors that belong with it.
