Addition Construction
Make room for the way you live.
RAA Construction Group coordinates the design, engineering, permits, and construction of home additions and second-story projects across the San Fernando Valley and Los Angeles.
Design-build construction
One team for a larger footprint
Home additions bring together design decisions, architectural and engineering input, permits, inspections, and construction. RAA’s design-build process keeps those pieces under one project manager, from the initial scope through the final walkthrough. The service can support additions and second-story projects as part of a broader residential construction plan.
Think beyond added square footage
Plan the connection between old and new
An addition affects more than the new room. The design must account for how the expanded space connects to the existing floor plan, structure, utilities, exterior finishes, and daily life in the home. Early planning helps clarify whether the project is best approached as a ground-level addition, a second story, or another configuration supported by the property and local requirements.
A coordinated build
From first plans to final walkthrough
RAA’s process begins by understanding your goals and translating them into a clear scope with architectural and engineering input. The team then coordinates selections, permits, plan-check corrections, inspections, construction, and punch-list delivery. With design and construction connected under one contract and one point of accountability, homeowners have a clearer path through the decisions required for a substantial home addition.
