Architectural design, permit-ready plans and construction, all under one roof. ADUs, additions, SB9, full remodels and custom homes, designed in-house and built in-house by a family-owned team.
Pick your project. We handle the drawings, the permits and the build.
Floor plans, 3D renderings and walkthroughs, plus permit-ready plan sets with structural engineering and Title 24. We can pull the permit too.
Garage conversions and new detached units for rental income or multi-generational living.
Moving walls, full kitchen and bath redesigns, and whole-home transformations, not quick cosmetic fixes.
More bedrooms, a bigger kitchen, a primary suite, designed to look like it was always there.
Split your lot or add a second unit under California's SB9, from feasibility to final inspection.
From empty lot to move-in: a ground-up home designed and built by one team.

Patsy and Pino Tenerelli met in 2007 and have been building together ever since. In 2016 they founded a residential redevelopment company that has transformed more than 60 properties.
