• Take the 5 x 5000mm long fl oor joists and lay them out
parallel to each other on their short edges as shown
(45mm face to the ground). Lay the 2 x 2000mm Joists
across the ends.
• Using 8 x 75mm screws, screw the outside joists
together at the corners using 2 screws per corner.
• Take 1 x 444mm Joist, and using it as a measuring
packer, position the next internal joist at one end and
fasten with 2 screws. Repeat at the other end.
• Position and attached the other remaining 2 x joists the
same way.
• Measure in 1200mm from the LH end and mark the
centre position on all joists. Take 1 x 444mm joist and
align it with the centre mark. Screw in from the outside
using 2 x 75mm screws. Next, measure 2400mm in
from the LH end and mark the centre position on all
joists. The other 3 x 444mm joists should be positioned
and screwed into place as per the diagram
• When completed, Measure
diagonally

outside corner to the other, note the measurement and
then meaure the opposite diagonal distance. These
measurements must be the same for the shed to be
square. Adjust if necessary

• Place one sheet of plywood in position running from the front
to the back of the shed as per the diagram.
• Align the sheet with the edges of the fl oor frame, take
20 x 40mm screws and fasten the ply wood to the joists and
base plates as shown (red dots). As the ply only overlaps
half of the centre joist, angle the screws inwards to ensure
thatthey don’t miss the joist. Repeat with the other sheet.
• Lift the shed frame onto the fl oor and align the frame with all
edges of the fl oor. Once again check that the shed is square
using the method described above.
• Screw the shed frame to the fl oor using 1x 100mm Tek
screws through the bottom plate as per the red dots in this
diagram.
Now we need to remove the bottom plate in the doorway
at the front.
• With a handsaw, cut through the bottom plate fl ush with the
door studs on either side and discard the centre piece.
• Attach door step fl ashing using 3 x 30mm screws, screwing
through the top of the top of the fl ashing.
