What Services We Offer
Comprehensive Construction
and Development Services
From full-scale apartment buildings to precision trade work, Xtraunit delivers excellence at every stage of the build. Our in-house teams and efficient workflows ensure each project moves smoothly, with quality you can see and a process you can trust.
Xtraunit’s design-build model turns complexity into speed. With one integrated team managing design, permitting, and construction, we eliminate inefficiencies and deliver high-quality housing on faster timelines. In-house trades, clear communication, and data-driven decisions power every phase—from entitlement to lease-up. In today’s urgent housing climate, smarter planning means faster delivery.
For Xtraunit, affordability is more than policy—it’s a commitment. We specialize in deeply affordable and mixed-income housing aligned with LA’s Housing Element and ED1. By leveraging density bonuses, rezoning, and AB 2334 incentives, we unlock sites that drive long-term community impact. Real affordability, built right, creates real change.
Through a unique combination of engineering, construction and design disciplines and expertise, Concor delivers world class infrastructure solutions to customers and stakeholders across a broad range of industry sectors.

What Sets Us Apart
14
years Experience
★★★★★ 5/5
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.
