Ground-level deck, 3 x 3 m
The smallest job that still needs a proper frame. At this height there is no guard to build and no step, so the list is boards, joists, beams, footings and fixings. It suits a seating corner or a hot tub base where the ground is already fairly level.

Open this project and make it yours.
The designer opens with this deck already drawn. Change the size, the height, the material, railing, steps or country, inspect the full take-off and save a summary PDF. The complete pack adds the merchant order file and site documents.
Open in the designerFree, no sign-up. This is a material take-off, not a structural design; spans, footings and guards still need checking against local rules.
