Design a deck with AI
Describe the deck you want — “a 16×20 attached deck, 8 ft off grade, with stairs on the long side” — and Grovec sizes the joists and beam, spaces the footings, details the ledger connection, and builds the materials list.
Joists, beams and footings — all spanned
Deck framing lives and dies on spans and the ledger. Grovec sizes joists and the beam from real span tables for your spacing and species, spaces the footings to carry the load, and details the ledger-to-house connection and railing posts — the spots inspectors look at first.
Stairs, multi-level decks and freestanding decks are all supported, each framed and checked rather than sketched.
Every board and fastener, counted
The bill of materials is generated from the model: joists, beam plies, decking boards, posts, footings, railings and the structural hardware to connect them. Adjust the size or height and the count follows.
Permit-ready and exportable
Generate a span-checked framing plan and permit documents, and export to IFC, Revit and DXF. The code gate blocks submission on an over-spanned joist or beam, so you fix it before the building department does.
FAQ
Does it size the joists and beam, or just draw the deck?
It sizes them. Joist and beam spans are checked against real tables for your spacing and species, and the design is blocked on a code error.
Can it do stairs and multiple levels?
Yes — stairs, multi-level and freestanding decks are supported, each framed and span-checked.
Do I get a materials list with fasteners?
Yes — a part-by-part bill of materials including decking, framing, footings, railings and structural hardware.
Is it free?
Yes — start designing free and upgrade when you need more.
