Reviews

What Chicago homeowners say.

"Chicago Constructions added a 400 sq ft sunroom off our kitchen in six weeks. The brick blend is spot-on and the skylight placement gives us morning light exactly where we wanted."

David R.
Sunroom Addition

"They converted our dusty attic into a legal bedroom with dormers and a full bath. Passed every inspection without delays and even matched the original hardwood flooring."

Lisa M.
Attic Conversion

"Our coach-house ADU went from permit to tenant-ready in four months. Separate ComEd meter and sound insulation between floors make renting effortless."
