Custom Home Additions

Build a home addition that feels original to the house.

Custom home addition designed to blend with an existing residence
More Home, Thoughtfully Added New square footage that looks and feels like it belongs.
Designed Around the Existing Home

The best addition feels original to the house.

H&M Construction considers exterior proportions, interior circulation, structural requirements, and finish continuity so the new space improves the entire home—not only the added room.

Design

Architectural Integration

Rooflines, windows, exterior materials, ceiling heights, and transitions are planned to create a cohesive finished result.

Coordinate

Structure & Home Systems

Framing, foundation work, electrical, plumbing, heating, cooling, and connections to the existing home are organized together.

Finish

Interior Continuity

Flooring, trim, doors, lighting, paint, and other details are selected and installed to support a natural flow between old and new.
