BASE PREPARATION
The following table gives the external dimensions for a brick base. Look for your building
size in the left hand column and read across for the width and length.
The dimensions allow the lips of the cills to overhang. This helps prevent water running
back into the greenhouse.
When building your base make sure the diagonal measurements are equal.
