Recent Office Projects

Real recent projects, real prices.

Three real i30 office projects from the last year, with the actual price each client paid. Same labor pool, same scoping discipline, very different scopes. That’s why your number depends on the specifics, not the square footage.

Project 01 · Rowlett, TX

Office repaint + small partition

$7,800

1,100 SF · 3 days

Repaint walls and trim, build a new 12 LF partition wall, hang a door, install trim, lay carpet through the connected room. Occupied office; work sequenced around the tenant.

Project 02 · McKinney, TX

Medical front-of-house rebuild

$38,000

Full waiting-room and reception rebuild for an active medical practice: demo, new flooring, paint, reception millwork, and a lighting reset. Clinical areas protected from dust; practice stayed open.

Full case study →

Project 03 · Longview, TX

Office restrooms + break room

$62,000

Gut and remodel of two office restrooms plus the staff break room inside an active professional-services tenant. Plumbing coordination, new tile and fixtures, and break-room millwork, sequenced so the office always had at least one functional restroom on the floor.

Larger or specialty projects (full medical-grade TI, lab-grade MEP, executive finishes) run higher. Tell us your scope and we’ll come back with a real range, no $/SF guessing.

What Drives the Final Number

Up and down, the honest answer.

Pushes price up

  • ▲MEP rerouting (moving HVAC, plumbing, or electrical from existing locations)
  • ▲After-hours or weekend work in occupied buildings
  • ▲Specialty finishes (real stone, custom millwork, glass partition systems)
  • ▲Compressed schedules requiring overtime or larger crews
  • ▲ADA scope uncovered during the site visit
  • ▲Landlord-imposed building rules (after-hours freight elevator access, MEP shutdowns)

Keeps price down

  • ▼Simple finish package: LVP + paint + standard ACT ceiling
  • ▼Keeping MEP where it is when the layout allows
  • ▼Flexible schedule that lets us sequence trades without overtime
  • ▼Walking the space with us early so scope is locked before mobilize
  • ▼Reusing existing doors, frames, and built-ins where condition allows

Doctors' Office Reception & Check-In Rebuild, Mansfield, TX

Mansfield, TX

Doctors' Office Reception & Check-In Rebuild

Reception rebuilt in a doctors' office in Mansfield. The glass-enclosed check-in window came out, the openings were reframed with painted mullions, and the counter was rebuilt with a dark wood slat front under a light stone-look top, mitered and returned down the end of the run. A lower counter section sits at the end of the run beside a pass-through to the adjoining room.

Common Cost Questions

Frequently asked

How much does an office build-out cost in DFW?+

Real i30 office work spans a wide range because the price depends on scope, not square footage. Three recent examples: a 1,100 SF Rowlett office with paint, a new 12-foot partition, a door, trim, and carpet ran $7,800; a McKinney medical practice's front-of-house / waiting-room rebuild ran $38,000; a Longview gut-and-remodel of two office restrooms plus the staff break room ran $62,000. Larger or specialty projects (full medical-grade TI, lab-grade MEP) run higher. Share your scope and we'll come back with a real range.

What is the office build-out cost per square foot in DFW?+

We don't publish a $/SF number for office work, because in our actual work it doesn't predict the number. A 1,100 SF light scope ran $7,800 (about $7/SF); a smaller-footprint restroom + break-room gut ran $62,000 (well into the $100+/SF range). The square footage isn't what's expensive. The scope is. We'd rather give you a real number against your actual scope than a $/SF estimate that misleads in either direction.

What drives an office build-out cost up?+

Five things consistently push the number up: (1) MEP rerouting, which means moving HVAC, plumbing, or electrical and adds trade time; (2) after-hours work in occupied buildings; (3) specialty finishes (real stone, custom millwork, glass partitions); (4) compressed schedules that force overtime or larger crews; (5) ADA scope or code compliance work uncovered when we visit the site.

What keeps an office build-out cost down?+

Honest answers: pick a simple finish package (LVP + paint + standard ACT ceiling), keep MEP where it is when possible, give us a flexible schedule, and visit the space with us early so the scope is locked before we mobilize. Surprises mid-build are what push budgets up.

Is the price you quote the final price?+

Yes. Our scopes are written line by line and the price is locked at signing. Change orders only happen if you request a scope change, and they're priced and approved in writing before work starts. No surprise overruns absorbed into the final invoice.

Do you charge for the site visit or the written scope?+

No. Site visits and the written scope are free. We don't ask for a deposit until you approve the scope in writing. Most site visits scheduled within 5 business days.

What's included in the price?+

Labor, materials, permits, city inspections, and project management. Landlord-imposed fees (TI allowance reconciliation, building-rule compliance fees) and FF&E (furniture, fixtures, equipment) are typically separate line items. We call them out explicitly in the written scope so there are no hidden costs.
