Attic conversions

If your attic has a real staircase and enough headroom, it may already be a bedroom or office waiting to happen. If it doesn't, a dormer can fix that.

Will your attic work?

  • Headroom. Habitable rooms need enough ceiling height over a large share of the floor. Many Capes and colonials need a dormer to get there.
  • Floor strength. Attic joists were often sized for storage, not bedrooms. We check and reinforce.
  • Stairs. Pull-down ladders don't count. The space needs a code-compliant stair.
  • Egress. A bedroom needs an escape window, which a gable or shed dormer can provide.
  • Comfort. Insulation and heating and cooling make or break an attic room.

What we build

Bedrooms with closets, home offices, kids' playrooms, and primary suites with a bath. We handle structure, insulation, HVAC, electrical, finishes, and permits.

Typical cost

Attic conversions without dormers typically run $30,000 to $60,000. With dormers and a bathroom, expect $60,000 to $120,000.

Can I put a bedroom in my attic in New Jersey?
Yes, if it meets code for ceiling height, egress, stairs, and smoke and CO protection. We assess all of that at the estimate.
