Long Island Dormers & Extensions

Dormers & Extensions

Add square footage without leaving your neighborhood — dormers, rear extensions and second-story additions.

Overview

Dormers & Extensions done right, the first time

When Long Island families outgrow their home but love their school district and neighborhood, dormers and extensions are usually the smartest move. ORA Construction designs and builds shed dormers, full second-story additions, rear extensions and side additions — fully integrated with your home's existing roofline, siding, and interior layout.

What's included

  • Shed dormers and full second-story additions
  • Rear and side extensions for kitchens and family rooms
  • Foundation extensions with frost-rated footings
  • Roof tie-ins that match existing pitch and shingle
  • HVAC, electrical and plumbing extension to new spaces

Our process

1. Feasibility

We review setbacks, lot coverage, and existing structure to confirm what's permittable.

2. Design & Permit

Architectural and structural drawings, town submission and variances if needed.

3. Build

Foundation, framing, weather-tight envelope, mechanicals and finishes — sequenced to minimize disruption to the existing home.

Shed dormers and full second-story additions is one of the most common reasons Long Island homeowners call us — and the area where shortcuts cost the most over a decade.— ORA Construction project lead

What Long Island homeowners say

4.9(100 reviews)
Had the sidewalk and pathway removed, and replaced. Very pleased with the result, looks great, nice having a new sidewalk. Will probably have more work done by Ora. Anthony was very helpful.

Sidewalk & pathway replacement · Syosset, NY

Recently, Anthony and his crew removed and re-surfaced our driveway. He completed the job as scheduled. We were very satisfied with the results and would whole heartedly recommend him for your home improvement needs.

Driveway removal & resurfacing · Manhattan, NY

Anthony built our new home and we couldn't recommend him more highly. His attention to detail is unreal — every room and every finish is exactly where it should be. His eye for design elevated our plans in ways we didn't know to ask for, and the choices he nudged us toward are now the things we love most about the house. On top of that, his deep roots in the community showed up everywhere: top-tier subs whom we loved working with, fast answers from local officials, and the right person for every question we had. A true craftsman and a genuinely good guy to work with.

Answers

Dormers & Extensions — FAQs

Can you build a dormer over my existing roof?+

In most cases yes. We engineer a structurally compatible roof tie-in and match siding and shingle so the addition reads as original to the home.

Will an extension require a variance?+

Sometimes. We screen for setback and lot-coverage issues during feasibility and handle variance filings when needed.
