Cape Cod dormers in Westfield, NJ

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

Westfield homes and adding space upstairs

Westfield has some of the best older housing stock in Union County: center-hall colonials, Tudors, and Victorians from the early 1900s through the 1930s, with Capes and split-levels filling in the post-war neighborhoods. Owners here expect high-end finishes and careful work around original details.

Colonials with walk-up attics

Many Westfield 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 Westfield 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.

Westfield is Cape Cod country

Westfield 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.

Westfield pricing

A finished rear shed dormer on a Westfield 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.

DMF coordinates the architect and engineer, files everything, and represents the project at a zoning board hearing if one is needed.

Westfield questions

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