## The Dual-License Advantage

AS Design Build is one of the few firms in Southern California where the architect is also the general contractor. This eliminates the common problems of hiring separate architect and contractor teams: miscommunication between design and construction, finger-pointing when issues arise, markup on markup, and designs that look great on paper but are difficult or expensive to build. When the person who designed the space manages the team that builds it, problems get solved on-site in minutes rather than through weeks of RFIs and email chains between two separate firms.
