Home Additions Built for Where Your Family Grows Next

You Love the House. You Need More of It.

A new baby. An aging parent moving in. A home office that has lasted three years too long at the kitchen table. Sometimes the right move is not a new home, it is a thoughtful addition to the one you already love. Uprite Plus has been building home additions in Long Island for 43 years. Seamless to the eye, solid to the structure, built to match the character of the original home.

Additions We Build

Second-Story Additions

A full floor added above an existing footprint. Primary suite, kids’ rooms, home offices, whatever your program calls for. Our second-story additions in NY include structural engineering, weatherproofing the occupied home below, and matching the exterior so it reads as original.

Dormer Additions

Shed dormers, gable dormers, and full-width dormers that add real headroom and daylight to upstairs spaces. Our dormer additions in Long Island are matched to the original roof profile, so they look like they were always part of the roof.

Rear & Side Extensions

Kitchen extensions, family-room bump-outs, primary suite additions, and sunroom extensions. Great light, great flow, and seamless integration with existing finishes.

Garage Additions & Conversions

Attached two-car garages, three-bay carriage garages, and conversion of existing garages into heated living space with proper insulation and code compliance.

Mudroom & Entry Additions

Small in footprint, massive in daily quality of life. Benches, cubbies, coat hooks, and dog-wash stations are the quiet luxuries a family actually uses.
