Home Additions and Extensions in New York

A vertical addition puts another floor on the house. We check the existing structure with your engineer, reinforce the foundation and framing where needed, replace the roof and extend stairs and systems upward.

Rear and side additions extend kitchens, family rooms and primary suites. We build a new foundation, frame and enclose the addition and connect it to the existing rooms and systems.

On townhouses and apartment buildings, a mansard or penthouse addition adds a top floor set back from the facade. We build the roof form, windows and any terrace to the approved drawings.

An addition should look as if it was always part of the house. We match brick, stone, siding, trim, windows and rooflines to the original, so the addition and the house read as one building.

Not every house can carry another floor. We assess the foundation and framing before design is final, and we underpin or reinforce them when your engineer specifies it.

Zoning sets how tall you can build, how close to the lot line and how much floor area the lot allows. We review these limits with your architect before drawings are final and prepare the permit filings.
