How It Works

Our Process

01

Consultation & Design

We meet on-site to understand your vision, assess the space, and explore design options that work with your home's structure and SF building codes.

02

Permits & Planning

We handle all permit applications with the SF Department of Building Inspection — one of the city's most complex processes.

03

Construction

Our experienced crew handles foundation, framing, roofing, MEP rough-ins, and all finishes with daily updates to keep you informed.

04

Final Inspection & Handover

We schedule and pass all final inspections, then walk you through every detail of your new space.
