Feedback from Lake County estate owners who transformed their lower levels with Assembly Squad.
"Our 5,000 sq ft estate had a completely raw basement that we'd ignored for years. Assembly Squad engineered a drainage solution for our clay-heavy lot, then built out a spectacular wine cellar, home theater, and wet bar. The craftsmanship is indistinguishable from our main floor finishes. Friends from Riverwoods and Lake Forest keep asking for their number. Absolutely world-class work from start to finish."
"We needed a private guest suite for my parents and Assembly Squad delivered beyond our expectations. They handled all the Bannockburn permitting, installed an egress window with zero damage to our landscaping, and created a beautiful self-contained apartment with a full kitchen and spa-like bathroom. My parents visit from out of state and now have total independence. The project finished a week ahead of schedule."
