CHOOSING A SITE FOR YOUR GREENHOUSE

If you already have a level, or nearly flat site it is an ideal place to position your greenhouse as it will require less work and make it easier to achieve a good floor area for the foundations.

The most common method when preparing a foundation is to lay paving slabs (ensuring an overlap of 6“) outside the dimensions of the greenhouse base.

Please be aware that overhanging trees can damage a greenhouse and to reduce the risk it is recommended to avoid such an area. However if this is not possible do not worry as pruning provides a solution to the problem.

PREPARATION OF BASES

When preparing a foundation for one of our greenhouses, we recommend you use one of the following:

1. Paving slabs and concrete pads

Example Slabbed base for a Cedar Greenhouse.

The base should be 4” wider than the outside dimension of the size of greenhouse you have chosen.

The base should be 4” wider than the outside dimension of the size of greenhouse you have chosen.

2. Brick plinth

Build brick plinth to our external dimensions of your greenhouse chosen

3. Dwarf Wall

Once you choose your size of greenhouse, have the wall built as close to the size as possible that has been quoted for. We allow a tolerance of 0-70 mm to accommodate different sizes of bricks, mortar joints etc. Once the dwarf wall has been constructed we would ask you to forward the external sizes of your wall and height at the doorway to us.

4. Concrete surround
