Six fittings cover most of what you’ll ever build
These aren’t illustrations — they’re the actual catalogue parts, rendered exactly as you’ll see them in the builder. Pipe structures are made of embarrassingly few shapes: learn these six and you can read any project plan.
PVC pipe projects people actually build
Rigid PVC pipe plus a handful of tees, elbows and crosses covers a surprising amount of backyard engineering. Start any of these projects from a blank sheet — same palette, same rules.
Greenhouse & hoop house
Stop hunting for PVC greenhouse plans — draw your own: arcs, purlins and door bracing counted to the last cross before you cut a single pipe.
Chicken coop & run
A light frame you can actually move around the yard. See where every corner joint goes before buying.
Furniture & shelving
PVC pipe furniture without welding: garage shelves, a shoe rack, a drying rack, a side table.
Kids fort & playhouse
A frame that survives being climbed on — plan the bracing in 3D, not after the first collapse.
Trellis & plant supports
Tomato cages, bean towers, garden arches. Cheap pipe, few joints, done in an afternoon.
Carts, stands & holders
A kayak cart, a banner stand, a fishing rod holder — the long tail of things pipe was never meant for.
Three steps from idea to shopping list
Pick your parts
Pipes, tees, elbows, crosses — a catalogue of real fittings with real sizes, not abstract tubes.
Snap them together
Parts click onto each other’s ports. Wrong diameter simply won’t connect — the check works while you build.
Take the list to the store
The frame becomes a parts list: name, size, quantity, pipe lengths. On your phone, ready for the aisle.
You don’t leave with a picture. You leave with a cut list.
This is the greenhouse from the top of the page, taken apart: every pipe length and every fitting, counted. Pipe projects fail at the store, not at the drawing — so the drawing has to end in a list.
Quantities come from the actual frame, joint by joint — not from a rule of thumb. Change the span and the list changes with it.
FAQ
Is the PVC pipe builder really free?
Yes. No sign-up, no ads, no trial that expires. Open it in the browser and build.
Do I need CAD experience?
No. If you can drag parts on a screen, you can use it. There are no layers, no command line, no month of tutorials.
Can I design a PVC greenhouse or hoop house with it?
Yes — a rigid frame from straight pipe and fittings is exactly what the builder does best. You get the full skeleton and a parts list with every pipe length.
Does it use Schedule 40 PVC or metric pipe?
The catalogue is metric: pipe from 16 to 110 mm, the sizes sold across Europe and most of the world. The geometry is what matters — a frame you draw here is the same frame in any size system, and the parts list tells you exactly what to ask for at the counter.
What pipes and fittings are in the catalogue?
Thousands of real items: plastic pipe from 16 to 110 mm and everything that joins it — couplings, elbows, tees, crosses, end caps. Not abstract tubes, but parts with true dimensions that sit on a store shelf.
Does it work on a phone?
Yes. It’s a web app: phone, tablet or desktop, any modern browser, nothing to install.
