What Sets Us Apart
We don’t hand off. We integrate. Xtraunit’s design-build model means our architects and engineers work directly with our construction managers from day one. That collaboration ensures every drawing is efficient, cost-aligned, and ready to build.
With in-house experts across architecture, structural, MEP, and civil engineering, we reduce coordination errors and accelerate approvals. And because we know LA’s zoning codes and permitting pathways inside and out, we design for smooth submittals and fast RTIs.
