Easy to follow and thorough, with dimensioned drawings, cut and shopping lists, a truss order sheet for your supplier and CAD files. The PDF opens with a permit drawing set you can adapt for your permit application.

Easy to follow, nothing left out

Every cut has a letter (A, B, C), and every step shows which lettered parts and which screws go together, so you build it like flat-pack furniture, one step at a time.

You also get dimensioned drawings, a materials and shopping list, a cost spreadsheet and CAD files, so the plans answer the questions that come up while you build.

Permit drawing set included

Permit drawing set included, ready to adapt for your permit application; some building departments require stamped drawings. The PDF opens with a permit drawing set for each size: a site plan template, footing plan, framing plan, elevations, section and details, a code reference table that names its topics, the load and span basis and a materials schedule. These are generic DIY drawings with no engineer's or architect's stamp, and the code table is a reference, not a guarantee that your office will accept them. The trusses are designed and stamped by your truss supplier. Have a licensed engineer or your local building department review the drawings for your site before you build or apply.

CAD files included

A SketchUp-ready 3D model (.dae, every board a named part) plus DXF drawings for AutoCAD, LibreCAD or FreeCAD, so you can change a size, add your lot lines or hand the drawings to a drafter.

What you build

Plans for a freestanding gable pavilion or two-car carport in 12 x 16, 20 x 20 and 20 x 24 ft sizes (post centers).

6x6 pressure-treated posts on standoff post bases and round concrete piers sized to hold the roof down, three-ply 2x12 beams butted over the posts and held by post caps, 4:12 gable trusses that you order from a truss supplier with the truss order sheet in the plans, 2x6 purlins, lateral bracing, knee braces and uplift connectors, with a metal roof or shingles over sheathing. The beams sit 8 ft 1 in above the footings.

The trusses come from a supplier

These plans do not design the trusses: you order them from a truss supplier with the order sheet, and the supplier sends stamped drawings. Check your local snow load and design wind speed too: the plans assume 30 psf snow plus 12 psf dead and 25 psf wind on the members.

Please note: important limits. These are general DIY plans for planning and reference, not engineered or stamped drawings, and not designed for your specific site or local code. Codes, permits and requirements vary by location and change over time, and plans can contain errors. Before you build, have a licensed engineer, architect or qualified contractor review them for your site and confirm requirements with your local building department. The builder is solely responsible for safe construction, permits and use. Provided as is, without warranty; liability is limited to the price paid. Digital download only. Check your local permit, setback, height, snow and wind rules before you build and call 811 before you dig. The trusses must be designed and stamped by a truss supplier for your loads. Piers, not a thin slab, hold the roof down. The builder is responsible for safe construction and for safe use.
