Rear additions, dormers, and second-story expansions.
The feasibility of an addition depends on the property, zoning, existing conditions, and the applicable New York City, town, or village review process.
We coordinate an initial property and scope review before design is finalized. A licensed architect or engineer determines code and zoning compliance and prepares stamped drawings when required.
What a home addition job usually covers
- Preliminary property and scope review before design is finalized
- Coordination with an architect or engineer for stamped drawings
- Coordination of filings with NYC DOB or the applicable town, city, or village authority
- Excavation, footings, and foundation or slab work
- Framing, roof tie-in, sheathing, windows, and weather-tight envelope
- Mechanical rough-ins, insulation, drywall, and finish through final inspection
Planning your home additions project.
The tie-in is the hard part
The connection between new and existing construction affects flashing, floor heights, structure, and finish transitions. Those details are reviewed with the design professional and documented in the scope.
Expect the house to surprise you
Opening an existing exterior wall can reveal concealed wiring, chimney chases, or framing conditions. The estimate identifies known allowances, and newly discovered scope is priced in writing before related work proceeds.
Filings run on their own clock
Plan review and permit timing vary between NYC DOB and Nassau County towns, cities, and villages. Approval timing is shown separately from the estimated construction schedule.
Common questions about home additions.
Do we need an architect?
An addition commonly requires drawings prepared and sealed by a New York State-licensed architect or professional engineer. The design professional and filing requirements depend on the property and jurisdiction; D&T coordinates with the owner's professional.
Can you build a dormer instead?
Often a shed dormer gets you most of the usable space of a full second story at a fraction of the structural work, because you are not re-supporting the whole house. On Capes and split-levels it is frequently the better value.
How long does a home addition take?
The schedule depends on the design, approvals, structural scope, material lead times, and site access. Filing and construction time are estimated separately in the written scope.
