We recommend using a Sand & Gravel Foundation and Floor System
because it is simple and cost effective to complete. Basic instructions are
highlighted below.
Material List:
One Cubic Yard of Sand- to cover 9’x13’ - 2” deep.
Landscape Clothe- to cover 8’x12’ footprint.
4x4 Cedar Foundation Framing - Included in Kit (Parts A & B).
Two Cubic Yards of Gravel (small) - to cover 8’x12’ - 4” deep.
4 Tie Down Kits or 16 pcs -12” long Rebar - Optional.
Instructions:
The first step to building a greenhouse is constructing a foundation, but
before you begin you should have a level site prepared.
A. Choose appropriate site.
B. Excavate 9’x13’ area to a depth of 2-3” and level dirt base.
C. Lay Sand approximately 2” deep on base. Pack and level.
D. Position 4x4 Cedar Foundation Framing on level sand base. Angle
screw 4x4’s together with 3” long screws (included).
Make sure your 4x4 footprint is square. To do this, use your tape
measure, and take two diagonal measurements of the base (One
from the front left corner to the back right corner and the other
from the front right corner to the back left corner). The base needs
to be adjusted until the two measurements are the same.
Optional- Secure 4x4’s to the ground with Tie Down Kit or drill and
hammer 16 -12” long Rebar pieces through 4x4’s into the ground..
E. Lay Landscape Clothe and cut excess fabric around the edges. Make
sure you use a ground cover (also called weed barrier) that is
made for landscaping and not black plastic or a tarp. Ground
cover will allow water to drain through the fabric while keeping
weeds from growing in your greenhouse.
F. Pack approximately 4” deep of small Gravel to complete foundation
and floor.

assembled. Lay approximately 2” of sand in base, pack
and level.
