Cape Cod dormers in Chatham, NJ

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

Chatham homes and adding space upstairs

Chatham Borough and Chatham Township are among the most sought-after addresses in Morris County, with colonials, Tudors, and Capes on tree-lined streets. Renovations here are about adding space and value to homes owners plan to keep for a long time.

Colonials with walk-up attics

Many Chatham 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.

Tudors and steep roofs

Steep Tudor roofs in Chatham often hide a lot of usable attic. A well-placed dormer can turn it into a bedroom suite without changing the character from the street.

Chatham is Cape Cod country

Chatham 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.

Chatham pricing

A finished rear shed dormer on a Chatham 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.

Chatham questions

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