Home Additions & ADUs
Custom extensions, second stories, and detached ADUs.
Expand your living space and maximize property value with custom home additions — master suite expansions, second-story pop-tops, and detached ADUs designed and built to blend seamlessly with your existing home.
Whether you need a rear great-room addition in Costa Mesa, a second-story pop-top in Laguna Hills, or a detached 720 sq ft ADU generating rental income in Santa Monica, we handle the feasibility study, setback analysis, architectural design, structural engineering, permits, and turn-key construction — all under one roof.
