Services

Six things we do, run by our own crews and a bench of subs we have used for years. If a job needs a trade we do not carry, we say so instead of learning on your dime.

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

Home Additions & Dormers

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

  • 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
