Home Additions
Expand the home you already love with a second story, private master suite, or larger kitchen—planned and built from permits through completion.
A home addition designed as part of the original house
A well-planned home addition creates the space your household needs without sacrificing the character and flow of the existing residence. AXMIS coordinates architects, engineers, permitting, structural work, utilities, waterproofing, and finishes around one buildable plan. The connection between existing and new construction is considered early so the finished addition feels cohesive.

Residential additions planned for Southern California homes
A successful addition requires coordinated zoning review, architecture, structural engineering, permits, utilities, waterproofing, finish integration, and construction sequencing. AXMIS manages these moving parts through one clear process.
What determines whether a home addition is feasible?
Feasibility depends on zoning, setbacks, lot conditions, the existing structure, access, utilities, and the intended scope.
Can the addition match the existing home?
Yes. Rooflines, openings, exterior materials, interior finishes, and transitions can be coordinated so the addition feels cohesive.
Does AXMIS handle plans and permits?
Yes. AXMIS coordinates design, engineering, permit preparation, agency comments, and construction around one project plan.

Before expanding your home
Timing depends on design, engineering, permitting, scope, and site conditions. A project-specific schedule is developed during preconstruction.
It depends on the scope and which systems or rooms are affected. We plan access, protection, utilities, and construction sequencing before work begins.
Size, structural complexity, foundations, utilities, finishes, access, and permit requirements all influence the final budget.
AXMIS serves the South Bay, Westside, and surrounding Los Angeles communities.
