Precision Remodeling Crafted Around Your Vision
Adding square footage is one of the highest ROI investments for Los Angeles homeowners. A successful room addition must feel as if it was part of the original architectural design. Our licensed engineers and master builders manage the entire lifecycle: soil testing, foundation footings, seismic shear walls, roof tie-ins, and matching exterior stucco and siding.
Whether expanding your ground floor for a grand primary bedroom suite and luxury bathroom or raising the roof for a complete second-story addition, we coordinate with the Los Angeles Department of Building and Safety (LADBS) to keep permitting swift and transparent.

Common Remodeling Questions
Can we live in our home during a room addition construction?
For ground-floor room additions, yes! We seal off the addition zone with heavy dust barriers and separate exterior access so your daily routine remains undisturbed.
How long does the city permit process take for a room addition?
In Los Angeles, architectural drafting and city plan check typically take 8 to 12 weeks. We actively expedite submittals to avoid delays.
Will the addition match our existing roofline and exterior stucco?
Yes. Architectural continuity is our hallmark. We match roof pitches, tile/shingle colors, stucco texture, and window styles seamlessly.
