All our greenhouses come with a two inch wide by four inch deep beam of cedar at the base, providing a wooden base making it possible to sit the greenhouse directly on level ground, however we recommend a solid foundation.
The most popular and recommended bases are a full concrete base or a perimeter footing of concrete (depending on your requirements) or paving slabs.
When you complete your order, we will send you the outside dimensions, which the foundations should be built to.
Your base should be flat, level (this can be checked with a spirit level) and square. To ensure the base is square you need to measure the sides and across the diagonals, if the sides are equal and the diagonals are equal the base is square.
Do not worry, we are always here for help and advice after you have placed your order.
