Two-story modular rooms bring administrative and support functions into a vertically arranged plan.

Call (888) 697-6368: (888) 697-6368 ## Selections that shape both levels Review the structure and circulation before concentrating on interior colors. They determine how useful the added rooms will be. - Match an engineered steel deck to the planned live loads. - Locate interior or exterior stairs with handrails, landings, and non-slip treads. - Carry matching insulated wall finishes across both office levels. - Separate HVAC zones to account for different temperatures upstairs and downstairs. - Preassembled electrical, LED lighting and data pathways serve both occupied levels. - Include guardrails and kick plates wherever the selected deck arrangement needs them. ## Functions worth placing above the floor - Engineering desks above floor-facing supervisor rooms. - Training space over a shipping administration area. - Administrative departments within a constrained warehouse footprint. - Upper-level meeting rooms separated from routine dispatch conversations. ### A measured route to a second level Review space limits Compare stacked layouts Approve the scope Arrange field coordination ## Make the vertical space work for your departments Space constraints in St. Charles, Hazelwood, and O'Fallon make the whole arrangement important, not just the upper room. Stairs occupy space outside or inside the office outline. Their position changes how people approach the building, where furniture fits, and how much ground-level area remains available for warehouse activity. Newer St. Charles County, Earth City, and Hazelwood distribution buildings may offer 32–40 ft clear heights. Measure actual obstructions; roughly 18–20 ft usable height is an initial discussion range, not an assured two-level fit. The structural steel deck must match the intended upper-level use. Desks, stored files, and a room filled for training create different planning questions. Panel Built, a US manufacturer, supplies the modular system; engineered drawings describe the selected arrangement. We review the manufacturer warranty alongside the scope so documentation is part of the purchase discussion. Your project manager coordinates the installation sequence and delivery approach. Experienced installation crews are scheduled and managed by us. Vetted installation partners support the field work, with access and staging reviewed beforehand. This matters when occupied departments and active warehouse routes must remain distinct from the installation area.
