i30 Builders, a general contractor based in Royse City, TX, builds out leased office space across Dallas-Fort Worth and East Texas. That runs from blank shell to punch-complete handoff: partitions and doors, ceilings and lighting, flooring and paint, data and power, and the mechanical work the layout needs. Each job is scoped and priced per project after a site walk, lump sum from a written scope before any deposit, with no published starting price, and we pull the permits and schedule the inspections.

Common Questions
An office build-out is the interior construction that turns leased space into a working office: partitions and doors, ceilings and lighting, flooring and paint, data and power distribution, and whatever mechanical work the new layout requires. The starting condition drives most of the cost. A second-generation office that already has ceilings, restrooms, and distributed HVAC needs far less than a raw shell where none of that exists yet. Build-out and finish-out describe the same work, and the terms are used interchangeably in this market.
Typically: demo of existing conditions, framing, insulation, drywall, electrical rough-in and trim, plumbing rough-in and trim (where applicable), HVAC ductwork and diffusers, flooring, paint, millwork, lighting, and a final inspection. We provide a line-item scope so you know exactly what's covered.
Scope-dependent. A 1,000 to 3,000 SF standard office build-out typically runs 4 to 8 weeks from demo to certificate of occupancy, assuming permits are approved before we start. Larger or more complex spaces, like MEP-intensive or multi-phase work, run longer. We give you a schedule before we start, not guesses.
Yes. We can schedule work during off-hours or weekends, use dust-containment systems, and sequence trades to minimize disruption to adjacent tenants or base-building operations. See our Phased Renovations page for more detail.
Open-plan workspaces with workstation infrastructure, private offices and manager suites, conference and collaboration rooms, reception and waiting areas, break rooms and kitchens, and hybrid layouts with hot-desk zones. We work from your floor plan, or help you think the layout through before you engage a designer, because the number of walls moves the price more than the finishes do.
We install conduit, pull points and junction boxes to your AV and IT vendor's spec, and coordinate with your technology integrator so the rough-in is ready when they arrive. We don't supply AV equipment or program systems. That is your integrator's scope.
The build is finished to the last detail before any furniture goes in. Final cleaning, floor protection removal and a walkthrough with your representative happen before you move equipment in, and the punch list is closed before final payment.
Absolutely. We submit permit drawings, coordinate city inspections, and align scope to the landlord's building rules and TI allowance terms. Managing that triangle is a core part of what we do.
Project Proof
Rowlett, TX
1,100 SF Rowlett office, full repaint of the suite plus a new room added inside: framed and finished a 12 LF partition wall, hung a new door, ran trim, and laid carpet through the new room and its connection. Three trades sequenced into one tight window, with the adjacent offices working through the day.
