Roselle Park homes and adding space upstairs
Roselle Park is a walkable borough of 1910s through 1940s colonials and bungalows on narrow lots. Space is at a premium, so finished basements and upward expansion are the smartest ways to add room here.
Older framing needs an engineer's eye
Pre-war Roselle Park 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.
Small lots: build up, not out
On Roselle Park's tight lots, a ground-level addition often runs into setback and lot-coverage limits. A dormer adds space inside the existing footprint, which often avoids that problem entirely.
Colonials with walk-up attics
Many Roselle Park 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.
Roselle Park pricing
A finished rear shed dormer in Roselle Park typically runs $90,000 to $150,000 with an upstairs bathroom. Gable dormers run $15,000 to $30,000 each.

Permits in Roselle Park
Dormers in Roselle Park need stamped drawings and a building permit from the Roselle Park construction office, and some projects also need a zoning review for height or bulk. DMF coordinates the architect and engineer, files everything, and represents the project at a zoning board hearing if one is needed.
