Reviews

What Chicago homeowners say.

"They turned our 900 sq ft attic into a master suite with skylights and a walk-in closet. Permits were filed Monday, construction started the next. Zero surprises."

James K.
Attic Addition

"Added a 220 sq ft kitchen bump-out with a breakfast bar. The new joists lined up perfectly with the old oak floor—can’t even tell where the house ends and the addition begins."

Lena M.
Kitchen Expansion

"Converted our detached garage into a rental ADU. Chicago Home Additions handled zoning approval and even installed a separate ComEd meter. Rent covers half the mortgage now."

David R.
ADU Conversion
