What goes into it
Shed dormers
The workhorse on a cape. A long, flat-roofed dormer that turns a cramped upstairs into full-height rooms.
Gable dormers
Smaller, peaked dormers that add light and headroom and keep the classic cape look.
Full second stories
A new floor on a ranch or a split-level. It starts with whether the foundation and the framing can carry it.
Attic conversions
Headroom, stairs, insulation and an egress window decide whether an attic can be a bedroom.
Zoning and height
Your town's height limits and other zoning rules come first. If the plan needs a variance, we find out early.
Matching the roofline
Siding, trim and roof pitch matched so the new floor looks original.

How much does a dormer or second-story addition cost?
A full second story is priced as its own line, shown on this page with the addition ranges. A dormer depends on its size and the roof work. Ballpark only. Your real number comes in writing after the consult.
Shed dormer or gable dormer: which is better?
A shed dormer adds the most floor space and headroom. Gable dormers add light and keep the classic look. Plenty of capes get a shed in back and gables in front.
Can my ranch take a second story?
Sometimes. The foundation and the walls have to carry the new floor, and an engineer has to say so. We start there.
Do I need zoning approval for a second story?
The plan has to meet your town's height limits and other zoning rules. If it doesn't fit, it needs a variance from the zoning board. We check before any drawings get made.
Can we stay in the house during the work?
With a dormer, often yes. A full second story usually means the roof comes off for a stretch, so plan for that. We go over it at the consult.
Can my attic become a bedroom?
Maybe. It needs enough headroom, real stairs, floor joists that can carry a bedroom and an egress window. We check all 4 at the consult.
