Design a pergola in seconds.
Size posts, beams, and rafters with sliders — no CAD skills. Pick from six roof styles, go freestanding or attach it to a wall, add screens, planters, and a bench, all in a live 3D preview. Free, in your browser.
Pick a roof
Six roof styles, one click
Open rafters, a pitched gable, a cross-hatched lattice, fixed or adjustable louvers with a live blade angle, or a solid / shade-cloth panel — swap the whole roof instantly and the frame adapts.
Shape it
Every beam and rafter is a slider
Set width, depth, and height, post size and shape, single or doubled beams, rafter spacing and cantilevered tails, decorative end cuts, louver angle, and more — with a live 3D preview and instant presets.
Export it
Download a real 3D model
Export your pergola as a GLB (with materials) or an OBJ (geometry only) — free, with no sign-in — ready to open in Blender, SketchUp, or any 3D app.
A pergola, built from parameters
Design it free, right in your browser
Real posts, doubled beams, cantilevered rafters, and knee braces — every member sized from a slider, so a whole shade structure is a tiny editable recipe you can restyle in seconds.
A parametric pergola studio, in one tab.
Six roof styles
Open rafters, gable, lattice, fixed and adjustable louvers, or a solid / shade panel — switched in one click.
Full parametric control
Size, posts, beams, rafters, overhangs, end cuts, and louver angle — every member is a live slider in 3D.
Freestanding or attached
Build a standalone pergola or a wall-mounted lean-to with a ledger — the frame and rafters adapt automatically.
Real materials
Cedar, redwood, pressure-treated pine, hardwood, painted, powder-coated aluminium, and composite finishes.
Screens, planters & bench
Add crossed-slat privacy screens, corner planter boxes, and a built-in bench around the frame.
Export GLB & OBJ
Download your pergola with materials as a GLB, or geometry as an OBJ — free, no sign-up, for any 3D app.
Pergola questions, answered.
What is the pergola designer?
It is a free in-browser tool for designing a pergola with sliders, built into the home editor. Set the size, posts, beams, rafters, roof style, and material, and a real 3D pergola updates live in your plan — no CAD skills and no sign-up.
What roof styles can I build?
Six, switchable in one click: open rafters, a pitched gable, a cross-hatched lattice, fixed louvers, adjustable louvers (with a live blade angle and optional gutter), and a solid or shade-cloth panel.
Can I attach it to my house?
Yes. Switch Structure to Attached and the pergola becomes a wall-mounted lean-to: the wall-side posts and beam are replaced by a ledger board, and the rafters run from the front beam to the wall.
What materials are available?
Cedar, redwood, pressure-treated pine, tropical hardwood, painted white, powder-coated aluminium (white, black, or bronze), and composite — each rendered with realistic colour and finish.
Can I add screens, planters, or a bench?
Yes. Add crossed-slat lattice privacy screens on the back or either side, open-top planter boxes wrapping the corner posts, and a built-in bench across the back — all parametric and layered onto any roof style.
Can I get a materials list for my pergola?
Yes. The Design tab shows a cut list: every post, beam, rafter and brace grouped by size, with piece counts, total linear metres and board-feet, and a one-click copy as CSV.
Is the pergola designer free?
Yes — it runs entirely in your browser with no install and no licence. You can design a pergola and place it in a plan without an account; signing in just lets you save designs to come back to.
