Create the space your home needs by building upward. AXMIS manages structural engineering, permits, construction, and finish integration for a seamless second level.
A second floor designed to feel original to your home

AXMIS evaluates the existing foundation and framing, develops a buildable structural strategy, and coordinates architecture, engineering, permits, utilities, stairs, waterproofing, and finishes. Every transition is planned so the new level works naturally with the home below.

Structural, permitting, and design coordination under one team
Adding a level affects the entire building. AXMIS coordinates structural review, zoning constraints, stair placement, roof work, mechanical systems, waterproofing, and finish integration to keep the project buildable and predictable.
Can my home support a second story?
A structural evaluation determines whether the foundation and framing can support the addition or require reinforcement.
How is the existing home protected?
Weather protection, dust control, temporary barriers, site access, and construction sequencing are planned before structural work starts.
Can the new level match the original architecture?
Yes. The roof form, windows, exterior materials, interior details, and proportions can be designed for a cohesive result.

Home Addition Service Areas
Before adding a second floor
Yes. Plans typically require zoning review, structural engineering, and building permits before construction.
Stair placement is studied early because it affects both floors, circulation, room sizes, and structural framing.
Sometimes, depending on the construction scope and temporary utility interruptions. We define the practical occupancy plan before work begins.
Timing depends on engineering, permits, structural scope, finishes, and site conditions. AXMIS develops a project-specific schedule during preconstruction.
