Patiently, transparently, and to last. Years of accessory-dwelling expertise across Southern California, under one accountable roof.
Polestar is a design–build studio focused on one thing: turning Southern California backyards into real, permitted living space. Architecture, engineering, permitting, and construction all live under one roof so there’s one point of contact and one team accountable for the result.
We started because too many homeowners were caught in the gap between a designer who drew something beautiful and a contractor who built something else. We closed that gap by doing both.
Licensed trades, premium materials, and drawings detailed enough to build from without guesswork. Every project carries a 10-year workmanship warranty because we intend to be here in ten years.
No hand-offs, no mystery line items. Just a calm, well-charted path from first sketch to more space and lasting value.
Most builds fracture the moment the designer hands off to the contractor. We keep it whole — four commitments that hold from first sketch to final key.
Design and construction under a single contract — nothing falls between a designer and a builder.
Fixed-price contracts. The number we agree on is the number you pay; changes only in writing.
We know every planning counter in our service area and clear plan-check the first time through.
Licensed trades and premium materials, backed by a 10-year workmanship warranty.
