Panelized offsite construction is a building method where wall panels and floor cassettes are manufactured in a factory using CNC precision, then shipped flat-pack and assembled on-site. Panels arrive with windows, doors, cladding, insulation, sheathing, and MEP (mechanical, electrical, plumbing) pre-installed. This delivers up to 30% lower project cost, 50% faster delivery, and 90% less waste than traditional stick-built construction.

Modular construction ships fully-formed 3D boxes that take up large transport space and limit design flexibility. MBS uses panelized construction: flat, code-compliant panels that ship vertically and flat-packed on standard flatbeds within 1,000 miles. Think IKEA, but for buildings. You get factory precision and speed without the transport constraints or design limits of modular boxes.

MBS manufactures a 1,500 ft² home in one week in our St. Louis facility, then assembles it on-site to weather-tight lockdown in 4 days. A crew of 11 can assemble a 5,000 ft² building.

MBS is headquartered at: 921 N 20th Street, St. Louis, MO 63106 A 40,000 ft² CNC manufacturing facility. We deliver flat-pack panels on standard flatbeds to projects within 1,000 miles of St. Louis.

MBS offers fixed factory pricing and delivers up to 30% lower total project cost compared to traditional construction. Final pricing depends on project size, design, and site conditions. Get a quote for an accurate estimate.

Yes. MBS panels are engineered with BIM and manufactured to meet building codes, then assembled into fully code-compliant buildings on-site.
