Additions & New Construction
Home Additions & New Construction in Los Angeles, Thousand Oaks & Westlake Village
Expand Your Home with Seamless, High-End Additions
Additions run $150 to $350 per square foot and four to eight months — and most of those months pass before anyone picks up a hammer. Architectural plans, structural engineering and city plan check are the long pole, and the phase homeowners most often underestimate. The construction itself is predictable; the approvals are what move. We manage the design, the engineering and the plan check, and we detail the addition to your existing rooflines and materials so it does not read as an add-on.

Frequently Asked Questions
How much does a home addition cost?
Home additions generally run $150 to $350 per square foot depending on complexity, finishes, and whether the addition is single or two-story. We provide a detailed, itemized estimate for your specific project.
How long does a home addition take?
A typical room addition takes 4 to 8 months from permits through completion; larger additions or second-story expansions can take longer.
Will my addition match the existing architecture of my home?
Yes — we design every addition to blend seamlessly with your home’s existing rooflines, materials, and architectural style, so it looks original to the house, not tacked on.
Do you handle architectural plans and permits for additions?
Yes. We coordinate architectural design, structural engineering, and the full permitting process from initial plans through final city inspection.
