About - A-1CO

We are proud to say that we have built some amazing projects over the past 30 years. From the renovation of Will Rogers Park in Pacific Palisades, the famous Original Conga Room Club on Wilshire, many multifamily apartment buildings in west Los Angeles, custom and expensive hillside homes, a condominium project in Beverly Hills that won 3 Golden Nugget awards to a high tech, 8 story, 80 unit loft project in downtown LA.

We believe that three key factors contribute to the success of every project:

Principals take an active role in every project - providing cost‐effective solutions during the pre‐construction period and leadership during the construction phase
As hands‐on builders we have the technical expertise needed to design smart, cost‐effective building solutions
Our commitment to maintain an honest and open communication with the client, architect, engineer and other members of the team means that everyone is working toward the same goals - the client's goals - creating a productive and efficient environment
