As a school project, we had to design a module that combined urban gardening and events on the rooftop of Budafabriek, Kortrijk Belgium, which accommodates a FabLab (BudaLab) and different organisations, as well as event-space. It had to be easy-to-make, from readily available parts.
As a result, we came up with extruded equilateral triangles with a sac to hald earth & plants.
These modules are stackable, moveable, made from cheap timber, screws, PVC and elastic bands.
They can be used as planters, but also as bar tables and stools.
If you have a pallet at home, the timber can easily be substituted for pallet wood (one side is 60cm, a europallet is 120*80cm). WHAT DO YOU NEED FOR 1 MODULE?
3 Wooden planks 18*93 mm
PVC pipe diam 32mm, 1m
Varnish WHAT DO YOU NEED FOR THE GARDENING BAG
Anti-rooting textile TOOLS
-Wood saw (hand, band or circular saw are all good)
Chisel or grater
Brush or paint roller
Drill incl. philipshead bit & drills (diam. 4mm (predrilling) and 10mm) (preferable cordless > screwing)
Sanding paper (for example grades 120-220-600)
