Build Process

How We Build in the Bay Area

A high‑end, on‑site process designed for clean sites, precise detailing, and predictable timelines — the same discipline we apply to custom homes.

Step 1 • Permits & Compliance

Planning, Zoning & Title 24

We confirm setbacks, utilities, tree protection and access, then prepare submittals for planning and building. Structural notes and Title 24 energy documentation are included where required.

Step 2 • Architecture

Proportions, Materials & Glazing

We align cladding, reveals, and window rhythms to your home. Specifications include black‑finish Low‑E glazing, durable exterior systems, and Level‑5 drywall for a gallery‑grade interior.

Step 3 • Build & Schedule

Clean, Predictable On‑Site Execution

Compact crews, tidy staging, and milestone tracking. Typical pod timelines run 4–8 weeks after design sign‑off, depending on access and finishes.

Step 4 • ADU‑Ready Options

Future‑Proofed from Day One

We can pre‑plan bath/kitchenette locations, routes for utilities, and rough‑ins so a future conversion to a full ADU is straightforward.

FAQs

Quick answers to the most common questions from Bay Area homeowners.

Do you build on‑site or deliver prefab?

We build on‑site across the Bay Area for a perfect fit and minimal disruption. This allows precise placement, clean staging, and tailored utility runs.

What do projects start at?

Pods typically start around $550/sq ft (Core/Apex), Twin Peaks around $105K+, and Nova around $450/sq ft for larger footprints. Site conditions and customization apply.

Do you handle permits?

Yes. We guide planning/building submittals and coordinate Title 24 and structural notes as required by your city.
