Foundation

Note: Outside dimensions of greenhouse foundation are given under “Actual Sizes” on the price charts.
Floor
If you have not poured a concrete slab, you will need a walkway down the middle of your greenhouse. First, lay down landscape fabric over the entire floor. For an aisle of bricks: frame the walkway with treated 2 x 4 lumber, lay down 2″ of crushed rock, then 1″ of sand, and set the bricks with 1/4″ spacing. A final touch might be to plant lemon thyme between the bricks! Finish the remainder of the floor with 2″ of pea gravel.
- Aisle pavers/bricks, Pea gravel under benches
- All pavers – provides good drainage
- Concrete slab/tile – not too smooth or it gets slippery. Provide for drainage.
