The Foundation For Your Building
OPTION 1: Wood Platform
If you decide to build your own foundation, be sure to select the appropriate materials. These are the recommended materials for your foundation:
●2 x 4's (5cm x 10cm) Pressure Treated Lumber● 5/8" (1,5cm) 4 x 8 (122cm x 244cm)
●10 & 4 penny Galvanized Nails ● Concrete Blocks (optional)
The platform should be level and flat (free of bumps, ridges etc.) to provide good support for the building. The necessary materials may be obtained from your local lumber yard.
40,6cm/61cm16"/24"
To construct the foundation follow instructions and diagram. Construct frame (using 10 penny galvanized nails)
Measure 16"/24" (40,6cm/61cm) sections to construct inside frame (see diagram)
Secure plywood to frame (using 4 penny galvanized nails)
Allow 2 - 3 hours for construction.

Note: Platform/Slab will extend 9/16" (1,4cm) beyond floor frame on all four sides. Seal this 9/16" of wood with a roofing cement (not included), or bevel this 9/16" of concrete when pouring, for good water drainage.
OPTION 2: Concrete Slab
The slab should be at least 3" to 4"
●1 x 4's (2,5cm x 10cm) (will be removed once the concrete cures)
●Concrete ● Sheet of 6 mil plastic
●We recommend for a proper strength concrete to use a mix of:
1 part cement ● 3 parts pea sized gravel ● 2 1/2 parts clean sand
1.Dig a square, 6" (15cm) deep into the ground (remove grass).
2.Fill up to 4" (10cm) in the square with gravel and tamp firm.
3.Cover gravel with a sheet of 6 mil plastic.
4.Construct a wood frame using four planks of 1x4 (2,5cm x 10cm) lumber.
