MBMI does not adhere to a one-size-fits-all, cookie-cutter approach. Each 30×40 is meticulously designed and engineered in-house to your local wind, snow, and seismic requirements, so pricing depends on your site, eave height, and the doors, windows, and accessories you select. For an exact number on your building, use the Price Calculator; it takes a few minutes and prices your exact spec.
Customization is made effortlessly accessible through our diverse selection of panels, doors, trims, and auxiliary accessories. Paint-coated panels come with a 40-year warranty, and design options like paint color and panel style let you match the building to your property.
Each structure is designed and engineered in-house, ensuring the highest standards of quality are consistently upheld. Comprehensive construction instructions are included with every building, and should any inquiries arise during the building process, our dedicated staff remains readily available to provide expert consultation.
