Design Your Own Metal Building — Free in 3D
Most "design your building" tools are a form that emails a salesperson. Ours is an actual 3D designer: you set the footprint, drag doors and windows onto real walls, pick panel colors, add a mezzanine, and lay out the rooms inside — then walk away with drawings, not a callback.
What you control
- Footprint and height — width, length, eave height, roof pitch
- Openings — roll-ups, walk doors, windows, placed exactly where you want them
- Colors — wall, roof, trim from real panel palettes
- Mezzanine level — structural deck, columns and stair
- Interior — rooms, walls, doors and MEP layouts on a floor plan
- 2D output — plan, elevations and a full spec sheet, exported as PDF
Why design before you quote
Steel is engineered to the inch — moving a door 4 ft is free in the designer and expensive after fabrication. A finished design with drawings is also what makes a quote accurate, and what a lender wants to see (see financing).
It's free, it runs in your browser, and your design saves to your account.
