Horizon Building Company provides comprehensive construction management services for commercial, multifamily, and residential projects throughout Los Angeles and Southern California. As your general contractor, we assume full responsibility for delivering your project on time, within budget, and to the highest quality standards.
Our construction management approach is built on institutional-level processes refined through over $600 million in project delivery. Principals John J. Daher and William W.

We understand that construction management in Los Angeles presents unique challenges including complex permitting processes, seismic requirements, coastal zone regulations, and a competitive subcontractor market.
