Expand the home you already love with a second story, private master suite, or larger kitchen—planned and built from permits through completion.

More Room for the Way You Live

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.

    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.

    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.
