Realistic 100x100 layouts

Clear-span industrial plant

100' column-free span, 26'–30' eaves, crane-rail-ready framing, two 16x16 grade-level doors, and a 25x100 mezzanine office along one sidewall.

Corporate hangar

A 100' wide door opening on one endwall with a hydraulic or bifold door, 28' eaves, and an insulated envelope with radiant tube heat.

What the price includes

A building package covers the engineered shell: primary frames, secondary framing, roof and wall panels, trim, fasteners, framed openings, and engineered drawings sealed where required. Freight is quoted by destination. It does not include the slab and footings, site work, erection labor, MEP, interior finishes, or permit fees.

At 10,000 sq ft, design wind speed, ground snow load, eave height, and door count are what move your final number. Request current package pricing and we will price the configuration with our manufacturing partners.

Engineering & site notes

Wind, snow and seismic
Loads come from ASCE 7 as adopted by your jurisdiction, not from a national default. This footprint is commonly engineered for up to 180 mph wind and up to 120 psf snow, but your county sets the actual values.
Foundation
A local engineer designs the slab and footings from the anchor bolt and reaction drawings shipped with your package. Soils, frost depth, and the loads you put on the floor determine thickness and reinforcement.
Insulation
Banded blanket insulation is the value option; insulated metal panels and spray foam cost more and perform better. If the space will be heated or cooled, decide before ordering — the envelope strategy affects framing and trim details.
Expansion
A 10,000 sq ft square footprint is a common threshold for full commercial plan review, fire suppression, and site civil work. Start permitting conversations before ordering.
Delivery
Ships by flatbed from the plant serving your region. Your site needs firm access for tractor-trailers, and offloading is arranged with your crew in advance.
