BudDIY: DIY Build Plans

BudDIY turns a rough idea into a detailed build draft. Tell it what you want to build and it calculates the materials, lays out the cuts and assembly steps, and draws an interactive 3D model you can orbit before you buy a single board.

Built for homeowners, not contractors. No engineering degree required.

SEVEN KINDS OF PROJECTS • Sheds — dimensions, foundation, flooring, doors and windows, framing, roof • Decks — framing, footings, decking, railings, stairs • Pergolas, gazebos, carports and patio covers • Fences • Paver patios, walkways and driveways • Water heater replacement and maintenance

SEE IT BEFORE YOU BUILD IT Every project gets a real 3D model that updates as you make choices. Orbit it, zoom in, and switch between three views: the finished exterior, the framing underneath, and an x-ray view that shows both at once.

EVERY BOARD COUNTED Materials are calculated, never estimated by guesswork. You get a full materials list with a cost estimate, a cut list, and a shopping list you can take to the lumber yard.

CHECKED AS YOU GO BudDIY checks your build as you design it — spans, supports, bearing, and structural soundness. When something won't work, it tells you why and, where it can, fixes it for you. Guidance cards explain the choices in plain English instead of code jargon.

STEP-BY-STEP BUILD SHEETS Generate an illustrated assembly manual for your project: numbered steps, labeled parts, per-step tool lists, and drawings for each stage of the build.

YOURS, ACROSS YOUR DEVICES Save designs, keep version history, and organize projects by property. Everything syncs across your iPhone and iPad. Share a design with a link, or start from one of our featured community designs.
