Reviews

What Los Angeles homeowners say.

"MDM added a 500 sq ft master suite that mirrors our 1950s stucco perfectly. Permits cleared in three weeks and the crew left our yard cleaner than they found it."

Carlos M.
Master Suite Addition

"Our garage-wall kitchen is gone and the new island seats six. The project finished two days early and the quartz seams are invisible."

Rachel T.
Kitchen Remodel

"The ADU now rents for $2,800 a month. They handled sewer lateral, electrical trenching, and even landscaped the path afterward."
