Mark Allan Contracting

Warehouse Conversion & Buildout Contractor in Georgia

The problem

You have shell warehouse space and a tenant who needs office, restrooms, and a use the building was not originally finished for. The gap between “empty box” and “occupiable” is where the budget lives, and you need it scoped honestly before you commit.

What's included

Real scope, trade by trade

  • Office and mezzanine build-in
  • Restrooms and ADA compliance
  • Demising walls and tenant separation
  • Dock doors, levelers, and man doors
  • Warehouse lighting and power distribution
  • HVAC for office and conditioned areas
  • Fire protection coordination
  • Epoxy and sealed floors
How it works

We walk the box with you and scope what it actually takes to occupy it.

1

Walk the space

We come out and look at what’s actually there — existing conditions, the capacity of the HVAC, electrical, and plumbing, and what your use will trigger for code and accessibility. Bring whatever you have: drawings, the lease exhibit, your target date. It takes about an hour, and we get on the calendar within days.

2

Get a real number

We scope it trade by trade — not a per-foot guess — and account for permitting and the long-lead items that actually move a schedule. You get a scoped estimate with the inclusions and exclusions spelled out, so you can hand it to your owner or lender and defend it. Not a range, and usually back in days.

3

We build

We pull the permits, order the long-lead items, and mobilize — self-performing the interior trades and managing the rest, in sequence. You get a point of contact and updates at the milestones that matter, through punch and closeout, including the documents you need to occupy.

Common questions

What does it cost to convert a warehouse for a tenant?
Warehouse conversions run a wide range — most of ours land in $75K–$500K — because the gap between an empty box and occupiable space depends entirely on how much office, restroom, and system work the use requires.
Do you build office space inside the warehouse?
Yes — office build-in, mezzanines, restrooms, demising walls, and the HVAC and power to condition them. That build-in is usually where most of the budget lives.
Can you add or modify dock doors?
Yes. Dock doors, levelers, and man doors are common in a conversion, and we coordinate the structural and site work they require.
