Due to the nature and size of the composting containers, the WooWoo GT 120 and GT330 containers require space under the floor of the building. As most buildings in the UK and Ireland don’t have enough underfloor space, you may have to create a special building. We offer free plans on the website that you can download, or we have flat-packed, self-assembly cabins (single, double and accessible) that can be delivered to your site.
