It is important that the floor be level and square. Square the floor as follows: before nailing the
flooring, measure the floor diagonally (corner to corner). Then measure the opposite corners;
these measurements will be the same when the floor is square. Toenail frame to the 4x4 runners.
Install the flooring with 8d galvanized nails spaced 8" apart.
3. Cut 2x4-12' floor joist to 11'-9". Treated lumber may be thicker than 1-1/2". Take this into
account when cutting the length of floor joists. Shorten joist measurements if necessary to
obtain 12'-0" building width.
2. Cut (2) two 2x4 joist headers to 16' - 0". Layout for 16" on center joist spacing. 'X' marks
where floor joist will be placed.
Foundation size is 12'-0" x 16'-0". Check local building codes in your area, the construction may
have to change. For a concrete slab, install sill sealer as a moisture barrier between the concrete
and the wall plates. Foam sill sealer can be purchased at home centers in rolls 3-1/2" or wider.
