Cape Cod dormers in Fanwood, NJ

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

Fanwood homes and adding space upstairs

Fanwood is a small, tree-lined borough right next to our Scotch Plains shop. Most homes are colonials and Capes built between the 1920s and the 1950s, many still carrying original framing, plaster, and foundations that need an experienced hand.

Colonials with walk-up attics

Many Fanwood 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.

Fanwood is Cape Cod country

Fanwood has a large stock of 1940s and 1950s Capes, built for a young family and now too small for most. A rear shed dormer is the most cost-effective way to add bedrooms and a bathroom here without giving up the yard.

Older framing needs an engineer's eye

Pre-war Fanwood 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.

Fanwood pricing

A finished rear shed dormer on a Fanwood 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.

Fanwood questions

Do I need zoning approval for a dormer in Fanwood?
Many dormers in Fanwood only need a building permit, but height, bulk, and setback rules vary by zone. We check your property against the Fanwood zoning code before design.
How long do permits take in Fanwood?
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 Fanwood?
Yes. DMF has built additions, second stories, and dormers across Union County and nearby towns. We can share nearby references at the estimate.
