Reviews

What Los Angeles homeowners say.

"Aggregate added 850 square feet to our mid-century home in Mar Vista. The new great room flows perfectly and the city inspector complimented the clean framing."

David L.
Home Addition

"Our garage is now a 420 square foot ADU that rents for $2,200 a month. They handled every permit and inspection without us lifting a finger."

Sandra R.
ADU Construction

"The kitchen expansion opened the whole first floor. We got a 10-foot island, hidden pantry and quartz counters that look like marble."
