What an office build-out inside a warehouse costs per square foot in Texas

The first question a tenant asks about a warehouse office is what it will cost per square foot, and the honest answer starts with a second question: how much of that shell were you planning to condition. A finished office inside an industrial building costs several times what the surrounding warehouse space costs, because it carries walls, ceilings, HVAC, lighting, restrooms and flooring that the open floor around it never needed.

A planning range, and why it moves

As a labeled planning range only, one that varies by scope, finish level and the year of construction, a basic office build-out inside a warehouse shell tends to sit well above the blended cost of the surrounding building, and it climbs from there with ceiling height, glazing, mezzanine structure and how far the space sits from existing power and plumbing. We do not put a number on a job until we have walked the shell and seen what the office footprint has to reach, because those two facts decide most of the range.

Splitting the air from the rest of the building

Conditioning an office pocket inside an unconditioned or lightly conditioned warehouse means new ductwork, a dedicated unit or a tap into existing rooftop equipment, and a ceiling built to hold it. The further the office sits from existing mechanical capacity, the more duct run and the more cost. A tenant who locks the office location early, close to existing roof equipment, saves real money over one who wants the office in the back corner of a large building.

Framing, ceiling and the wall that separates the two worlds

The wall between finished office and open warehouse usually carries a fire rating, and that drives the stud gauge, the drywall layers and the taping detail. A dropped ceiling, recessed lighting and acoustic tile cost more than the warehouse's exposed structure above it, and a two story office adds a second floor system, stairs and a landing that a single story build-out does not. Our framing, drywall and paint crews price this from our own production rates, which lets us hold a tighter number than a builder waiting on a subcontractor's bid.

Mezzanines add a structural line before framing starts

A mezzanine office over part of the warehouse floor adds a steel platform, a floor deck, stairs and guardrails ahead of any framing, and that structural package is priced separately from the interior finish that sits on top of it. Clear height under the mezzanine, the column spacing already in the building and the sprinkler layout above all affect what the platform can look like, so we ask for the layout and equipment plan before we price a mezzanine office.

Glass, power, data and restrooms

Glass walls between the office and the floor cost more than a solid partition and add glazing and framing detail a plain office skips. Electrical and data drops that did not exist in the open warehouse space run back to a panel that may need capacity added. Restrooms placed far from the building's existing plumbing stub-outs mean a longer trench and pipe run, which is one of the larger line items tenants underestimate on this building type.

What to send us

A shell survey if you have one, the square footage you want finished, whether the office sits on the slab or on a mezzanine, the ceiling height you need, and the date your operation has to be running. With those in hand we can tell you which line items are driving your number and tighten the range around your specific space.

We build office finish-outs inside warehouse and industrial shells with our own crews on the job and your move-in date as the target. Send over your floor plan and we will price the office against the specific shell it sits inside.
