Adding on in Port Washington

Timber-framed second-storey addition under construction on Long Island

Small-lot additions in Manorhaven are a setback problem; large-lot additions in Sands Point are a design-review problem. Different jobs entirely.

Shed and full dormers, second storeys, rear extensions and in-law suites, engineered to carry properly on the house you already have.

We survey the existing framing and foundation before drawing anything, so nobody promises you a bedroom the house cannot carry.

  • Permit filed with Town of North Hempstead, or one of several villages, and jurisdiction confirmed before drawings
  • Structural survey of the existing framing and foundation before design
  • Shed dormers, full dormers and full second-storey additions
  • Rear and side extensions, in-law and accessory apartments
  • Steel and LVL beam work where the span calls for it
  • Roof, siding and window matching so the addition does not announce itself
  • Phasing that keeps the house liveable and weather-tight throughout
  • Flood map and elevation certificate pulled at estimate stage for Port Washington parcels
Additions & Dormers — Port Washington specifics

Your existing
house is the
first constraint.

An addition is a structural question before it is a design one. What Port Washington houses were originally built to carry, and what town of North Hempstead, or one of several villages will approve, together decide how much room you actually get.

What you are adding onto

Waterfront and water-view houses, 1920s colonials, mid-century construction, and dense older housing near the harbour and Manorhaven.

Who reviews the addition
Town of North Hempstead, or one of several villages

Port Washington covers unincorporated Town of North Hempstead plus Port Washington North, Baxter Estates, Manorhaven, Flower Hill and Sands Point, each with its own review. Sands Point in particular is its own world.

What most often forces a redesign

Manorhaven is dense and low, Sands Point is large-lot waterfront, and both say Port Washington on the envelope. The construction reality is completely different.

Port Washington
questions,
answered.

Can I put a dormer or second storey on my Port Washington house?

Usually, but the existing structure decides. Small-lot additions in Manorhaven are a setback problem; large-lot additions in Sands Point are a design-review problem. Different jobs entirely.

Will an addition in Port Washington need a variance?

Manorhaven is dense and low, Sands Point is large-lot waterfront, and both say Port Washington on the envelope. The construction reality is completely different. We check setbacks and lot coverage against town of North Hempstead, or one of several villages requirements before design, so a variance is a deliberate choice rather than a surprise three months in.

What kind of house am I adding onto?

Waterfront and water-view houses, 1920s colonials, mid-century construction, and dense older housing near the harbour and Manorhaven. That original construction determines whether the foundation and framing can carry a second floor, which is the first thing we survey.

Can we stay in the house during the work?

Usually yes. We phase so the house stays weather-tight and liveable, keep the dust contained, and sequence the roof opening around the forecast rather than the calendar.

Does an addition trigger anything else in Port Washington?

It can. Manhasset Bay frontage, Manorhaven and the harbour edge are mapped and take water. In Suffolk, adding a bedroom or bathroom can also trigger a County sanitary upgrade. Both get checked at estimate stage, not at inspection.
