Cape Cod dormers in Union, NJ

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

Union homes and adding space upstairs

Union Township has one of the largest stocks of 1930s through 1950s Capes and colonials in the county. Many are on their original layout, which makes them ideal for dormers, finished basements, and bathroom updates that bring them up to how families live now.

Union is Cape Cod country

Union 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.

Colonials with walk-up attics

Many Union 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 Union 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.

Union pricing

A finished rear shed dormer in Union typically runs $90,000 to $150,000 with an upstairs bathroom. Gable dormers run $15,000 to $30,000 each.

Union questions

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