Room Additions

Adding to a house in Los Angeles isn't just framing — it's matching the existing roofline, working around the Baseline Mansionization Ordinance, hitting setback and lot-coverage rules, and finishing the new space so it reads like it was always there. We handle the whole arc: structural design, permitting through LADBS or your city, foundation and framing, MEP, and finish work — same family-owned team from first sketch to final walkthrough. Bedroom additions, primary suites, second stories, and bump-outs
