Home Additions in Nassau County & Long Island

Home additions, dormers, and second-story extensions across Nassau County and Long Island — designed and built to feel original to the house.

More space, without the move

When you love your neighborhood but need more room, an addition adds it without the cost and upheaval of moving. We design and build additions across Nassau County and Long Island that read as part of the original home — never bolted on.

From a primary-suite addition or kitchen expansion to a full second story or dormer, we handle the structural engineering, the approvals, and the construction so the new space connects properly in layout, rooflines, and finishes.

What an addition includes
  • Feasibility & zoning review
  • Architectural & structural design
  • Foundation & framing
  • Roofline & exterior integration
  • Mechanical, electrical & plumbing
  • Interior finishes
  • Permits & approvals
  • Project management

Additions are where design-build matters most: structural realities, budget, and design have to be worked out together, early, before anything is committed.

One team manages the whole expansion, so the addition feels like it was always part of the home.

Serving Cedarhurst, Woodmere, Lawrence, Hewlett, and Inwood across the Five Towns, and homeowners throughout Nassau County and Long Island.
