Workspace for Metro St. Louis Plants and Warehouses

# Modular Offices in St. Louis, MO

An enclosed office should support the floor around it. We plan panel rooms for Earth City distribution buildings, Berkeley aerospace operations and Fenton manufacturing space, with windows, doors and a footprint matched to the work.

Hot, humid summers and cold winters make HVAC a real part of the decision, not an afterthought. Bring us your available space and shift requirements; the free consultation includes a layout drawing and an itemized quote.

Call (888) 697-6368: (888) 697-6368

## Panel Rooms for the Way Your Facility Works

Put dispatch near receiving, give shift teams a conditioned break space, or separate a process from the surrounding floor. Choose the room by its job, then work through the footprint and building height.

## From Available Floor Space to Enclosed Workspace

A panel room is planned as part of your operation: its footprint, its temperature control and the way your team reaches it.

### A Layout Before You Commit

A free warehouse design consultation turns your available space into a layout drawing and itemized quote, whether the room sits in Earth City flex space or an older Berkeley plant.

### Keep the Working Aisles Open

Tenant space is finite. We compare the office footprint with storage, door swings and material movement so a Maryland Heights room does not consume the aisle your shifts depend on.

### Plan the Delivery Around Receiving

Panels, HVAC and electrical arrive preassembled. We coordinate unloading and staging with your receiving team around I-70 and I-270 truck activity, rather than assuming an empty dock.

### Assembly With a Named Project Lead

Our project manager coordinates experienced installation crews we schedule and manage. Vetted installation partners follow the manufacturer's specifications, with staging planned around multi-shift production and distribution.

### Engineered Panel Built Systems

We represent Panel Built, a US manufacturer supplying engineered drawings and warranty coverage. Wall, roof and HVAC selections reflect the difference between a tall St. Charles County distribution building and lower Fenton space.

### One Contact Through the Final Details

One point of contact keeps your drawing, selections and schedule together. Changes in staffing, shift access or room use come back to the same person, not a chain of separate suppliers.

Before the Layout Is Drawn

## Five Decisions That Shape Your In-Plant Room

A room that fits on paper can still interrupt a shift. Our consultation works through the tasks, approaches and overhead space before panels are selected. That matters in both older riverfront plants and tall Hazelwood warehouses.

### Your No-Charge Planning Package:

- Room purpose, occupant count and available footprint
- A drawing showing the proposed room arrangement
- Panel and roof choices with power and temperature control
- A project price broken out by the selected scope

Schedule Free Consultation (https://stlouismodularoffices.com/contact)

### Which jobs need to happen inside the room?

### Where do people and materials pass the proposed office?

### Will the room stand alone or meet existing walls?

### What space is available below the overhead equipment?

### Which power and HVAC arrangement suits the occupants?
