The Halls Qube greenhouse requires a base. It cannot be erected directly onto slabs or concrete.
A brick plinth can be laid out, or you could purchase a bespoke base. Cheaper and easier to install, this allows the greenhouse to be erected directly onto compacted soil. Only the corner anchors of the base need to be concreted into position to secure it.
If you’d prefer to construct a brick plinth, we can provide the exact outside base dimensions.
