How to make
A Narrow Backyard Shed
Page 5 of 7
Make up the floor frame on level ground.
Refer to the Parts List and floor layout plan
for individual member lengths and the floor layout. Use 90mm (3 1/2") galvanized nails for the floor frame and 'toenail' the joists to the skids.
Cover the floor with 18mm (3/4) inch treated plywood [e], nailing a maximum of 200mm (8") apart around the perimeter and along all joists using 60mm (2 1/2") galvanized nails.

Step 3. The Wall Frames
All the lumber used in the wall frames is 100x50 (2x4) stock however, the actual size of the stock when seasoned and dressed or surfaced is more likely
to be 90x45 (1 1/2"x 2 1/2). The plans reflect the actual size.
Make up the front, rear and two side wall frames using 90mm (3 1/2") galvanized nails.
Refer to the front wall plan
and the rear and side walls plan
for individual member lengths and wall layout.
Tie the opposing raking top plates [l] together with galvanized metal strap ties [p] (see fig.1).
You can go to the webpage at
https://www.buildeazy.com/plans/helpfiles_wallframes.html for more information on how to make Wall Frames.
Once the frames are made, squared and braced, lift them upright onto the floor and nail them together at the corners.
Ensure the bottom plates are straight and flush with the outer edge of the floor. Next nail the bottom plates
to the floor using 90mm (3 1/2") galvanized nails. Nail all along the bottom plates except
in the door opening. Cut that piece out with a handsaw.
Because the wall frames were made and braced square and the floor is level, the frames will automatically be plumb (vertical).
Step 4. The Roof Frame
Cut two rafters [z] to the dimensions as shown in the
front and roof plan.
Nail the two rafters [z] together at the top and also at the bottom to the top plates [z] ensuring that the rafters are centralized between
the front and rear walls.
Check that the rafters [z] and the raking top plates [l] on both front and rear walls are all parallel to one another and then measure, cut
and fix in place the ridge blocking [n] between the top of the rafters and the tops of the front and rear walls as shown in the above
Step 5.The Roof Sheathing
Cover the roof area with 12mm (1/2") plywood so that the plywood is flush with
the top of the rafters, the outside edge of the side walls and the outside edge of the front and rear walls.
Nail a maximum of 200 (8") apart along the ridge blocking [n], the rafters [z], the raking top plates [l] and the side wall top plates [g]
using 50mm (2") galvanized nails.
Note: The sheathing acts as a brace and also eliminates the need for a 'collar tie' which is a horizontal member that ties two opposing rafters
together and prevents downward spread.
