This Gardening Works Superior Big Square Compost Bin Module Add On is a three-sided Wooden Compost Bin for attaching to another bin sharing one side of equal length.

As used by Alan Titchmarsh, Pippa Greenwood and Monty Don on Gardeners World!

This Compost Bin features new and improved 18mm (2cm planed) board thickness as standard.


  • By utilising the posts on any side of the Wooden Compost Bin and sliding new panels into them you can double, treble or quadruple the size of your bin in just a few minutes. Choose a Module with at least one side to match your existing Compost Bin.
  • Multiple compartments allow for one side to mature whilst filling another.
  • Sliding panels for easy removal of finished compost. Get the wheelbarrow right up to your compost.
  • Solid wood is porous and insulating. Closed sides prevent uneven composting.
  • Suitable for garden and kitchen vegetable waste.
  • Designed to work below waist height preventing back strain.
  • Made from FSC certified wood dipped in a non-toxic wood protection which will not kill worms or bugs in the compost (they are not pressure treated/tanalised). It is recommended that you re-treat annually with a similar product or preservative when the wood is dry.
  • For use with the Gardening Works Big Square Compost Bin - 905 Litres
