Every addition is different. Some need a new foundation. Others tie into the existing roof. We plan each project step by step so there are no surprises — just a bigger, better home when we’re done.
Room Addition Construction Throughout LA County
A room addition lets you gain space without moving. Our projects include ground-floor family rooms, second-story bedrooms and bathrooms, and kitchen bump-outs that add 100 to 200 square feet. Every addition matches your home’s roofline, siding, and style. The goal is simple: it should look like it was always part of the house.
Engineering and Permits
Structural engineering is part of every project. Our licensed engineers check your foundation, bearing walls, and roof framing before we draw plans. We reinforce where needed and match roof pitches and materials. We also extend your HVAC, electrical, and plumbing systems into the new space.
Permits in Los Angeles usually take four to eight weeks after submission. Our team prepares complete plan sets that pass city review on the first try in most cases. Learn more about our room addition services, or read our room addition planning guide for step-by-step advice.
