Reviews

What Chicago homeowners say.

"JC turned our attic into a master suite with dormer windows and a walk-in closet. The crew finished in six weeks and the space feels like it was always there."

Lisa R.
Attic Addition

"They added 250 sq ft to our kitchen, installed a nine-foot island, and matched the 1920s trim perfectly. Permits were pulled before demo even started."

David M.
Kitchen Expansion

"Our brick two-flat now has a legal garden unit. JC handled zoning, separate ComEd meters, and soundproofing between floors. Rent covers half the mortgage."

Monica S.
