The standard and recommended foundation for cold frame greenhouses is a piered concrete footings.

The hoop sections of the structure bolt to the interior of the sidewall posts and they extend roughly 18" into augered holes which are then filled with concrete. These materials are the responsibility of the purchaser to secure and do not come with the structure.
