Warren homes and adding space upstairs
Warren Township in Somerset County is known for larger colonials built from the 1970s through the 2000s on big wooded lots, plus older farmhouses along the original roads. Many of those roofs, primary baths, and unfinished basements are now due for their first real update.
Bonus rooms and attics
Newer Warren homes often have an unfinished bonus room over the garage or a large attic. Finishing it with a dormer for headroom is often the simplest way to add a room.
Colonials with walk-up attics
Many Warren 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.
Space inside or out
On larger Warren lots, both additions and dormers are on the table. We price both so you can compare cost per usable square foot.
Warren pricing
A finished rear shed dormer on a Warren 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.
