Moon Design & Build

Residential design & build · Southern California

Drawn to be approved. Built by the people who drew it.

Remodels, additions and ADUs — from as-built survey to stamped set to finished construction, one team from the first call to the last inspection. Design by Moon, construction by our partner GNET.

01Services

Design · Permit · Build
  • 01

    ADUs

    Detached, attached and garage conversions. Feasibility, permit set, plan check and construction — one contract, one schedule.

  • 02

    Additions

    Second stories, room additions and structural openings, drawn to the current CRC and your city's amendments, then built to the set.

  • 03

    Whole-house remodels

    Reconfigured plans, new systems and finishes. Design decisions made with the crew that will build them, so the number holds.

  • 04

    Kitchens & baths

    The rooms that change a house most. Layout, cabinetry and fixture drawings, then a clean build with a fixed scope.

02Process

Five steps · design 6–10 weeks
  1. 01

    Consultation

    A 30-minute call or site visit. We confirm scope, zoning constraints and what the city will ask for.

  2. 02

    Survey & as-builts

    We measure the existing conditions and draw them up as the base for everything that follows.

  3. 03

    Design & drawings

    Plans, elevations and sections in the studio's lineweights, reviewed with you and the GC before anything is final.

  4. 04

    Plan check & permit

    We submit, answer corrections, and hand the crew a stamped set they can build from.

  5. 05

    Construction

    GNET builds from the approved set. Same drawings, same people, one point of contact through final inspection.

04Built by GNET

Construction partner

Moon draws it, GNET builds it. One team from the first sketch to the final inspection — so what gets approved is what gets built, at the number you were quoted.

GNET is a licensed Southern California general contractor specializing in remodels, additions, ADUs, kitchens and baths. They are in the room from the survey onward, catching the details that turn into change orders later — and then they build the set they helped shape.
