Cape Cod dormers in Madison, NJ

Shed dormers, gable dormers, attic conversions, and second floors for Madison homes, designed and built by DMF Construction from our Scotch Plains base, serving all of Morris County.

Madison homes and adding space upstairs

Madison, the Rose City, is a walkable Morris County borough with Victorians, colonials, and early 1900s homes around its downtown and Drew University. Owners here invest in quality and expect work that respects the house's original character.

Big attics in older homes

Madison's Victorians and older homes often have tall attics that can become a third-floor suite with a dormer or two. Historic districts may review exterior changes, and we plan for that.

Colonials with walk-up attics

Many Madison colonials have a walk-up attic with a real staircase. With a dormer or two for headroom and egress, that attic can become a bedroom, office, or playroom.

Older framing needs an engineer's eye

Pre-war Madison homes were framed for loads of their day. We have an engineer confirm the rafters, ceiling joists, and foundation before designing any new space upstairs.

Madison pricing

A finished rear shed dormer on a Madison Cape typically runs $105,000 to $170,000 with an upstairs bathroom, reflecting the finish level typical here. Gable dormers run $18,000 to $32,000 each.

Madison questions

Do I need zoning approval for a dormer in Madison?
Many dormers in Madison only need a building permit, but height, bulk, and setback rules vary by zone. We check your property against the Madison zoning code before design.
How long do permits take in Madison?
Plan on 4 to 8 weeks from design to permit for most dormers. A zoning variance, if needed, adds time for a board hearing.
Have you built dormers and additions near Madison?
Yes. DMF has built additions, second stories, and dormers across Morris County and nearby towns. We can share nearby references at the estimate.
