Design & Build Hub
One Team. One Contract. One Clear Path.

Welcome to the XtraUnit Design & Build Hub, where your entire project, from idea to keys, is guided by a single, integrated team. Faster timelines, lower costs, and buildable designs—all in one streamlined process.
Our Proven Process
A Transparent, Step-by-Step Path to Completion
Our process is built for clarity and confidence. We begin with a site and feasibility review, followed by smart conceptual design. Our engineers then develop full construction plans. We manage all RTI permitting in-house, overlap those efforts with preconstruction planning, and launch seamlessly into the build phase. Your project stays on track—from first sketch to final turnover—with one team driving every step.
Cost Control & Transparency
Design with Your Budget in Mind
At XraUnit, budgeting isn’t a final step—it’s built into every phase of design. That means no surprises, no sticker shock, and no need to redraw when bids come in. We provide phase-by-phase estimates, value engineering insights, and clear cost structures so you can choose between fixed-fee and cost-plus options.
We don’t “guess and check”—we plan and deliver.
Faster Project Delivery
Start Sooner. Finish Stronger.
With traditional models, there’s downtime between planning, permitting, and building. Not with Xtraunit. We overlap design and permitting, prep construction while approvals are underway, and coordinate with city reviewers in real time. That means fewer gaps, smoother inspections, and months saved on your delivery schedule.
Integrated Team Collaboration
Architects. Engineers. Builders. Working Together.
Design decisions shouldn’t be made in a vacuum. That’s why our architects, engineers, and builders collaborate from day one. Every drawing benefits from real-time construction input, ensuring it's both smart and buildable. Our engineers design for cost efficiency, our contractors flag potential issues early, and the entire team is aligned to your goals from concept to completion.
Fewer Delays. Better Value. Greater Control. Fewer Delays. Better Value. Greater Control.
Permit-Ready Plans (RTI)
Plans That Pass Review—Fast.
We specialize in RTI-ready design packages. That includes architectural, structural, civil, and MEP plans—plus Title 24 energy reports and full coordination with city departments. Our internal review process is built to catch issues before submittal, helping your project clear plan check faster and avoid costly resubmissions.
