1 pc - Front Door Assembly
2 pcs - Side Panel
2 pcs - Long Base Flashing
2 pcs - Short Base Flashing
2 pcs - Roof Panel

Step 2
Assemble Base:
If you have the double deep version, you will need to attach the floors together. Flip the floors upside down
on a flat surface as shown in the figure below. Use the 4 supplied 3” lag bolts with a washer to join the floors
together. If you only have one floor section, you can skip this.

Your floor will have metal support feet attached at each letter “A” marked above. They are designed to allow
for easy pickup and movement of the packaged building during shipping. If you wish, you may leave the feet
attached. If you have a double deep version, 2 extra feet are supplied. You can install them with 1 1/2” lag
bolts at position “B”. If you want the shed to sit closer to the ground, you can remove the feet, and support
the shed with small patio stones (or similar) at all points marked “A” and “B” above.
We recommend at least 1” of clearance from the ground to allow for proper ventilation to reduce
humidity under your building.
Step 3
Attach Flashing to Base:
Use the supplied wood screws to attach the flashing to the edge of the base. Long flashing on the front and
rear, short flashing on the sides. The side flashing will overlap in the middle. If you have only one floor
section, only one length of side flashing per side is required. Attach the corner flashing last. The screws
will drill through the flashing in areas where there is overlap.
Short edge flashing on sides
Long edge flashing on front and rear
Corner flashing last

Step 4
Level Base, Install Door and Side Walls:
After leveling the base, you can start installing the door and side panels. Position the front door assembly at
the front edge of the floor. Do not attach it to the base. Take one of the side panels that has a series of
notches punched along the long edge. It is this notched edge that will be inserted into a slot cut into the back
of the wood door post. Use the 1 1/2” lag bolts and washers to attach the side panel to the rear of the door post
(4 bolts are required). Attach the remaining notched side panel in the same way. You have now completed the
front half of the building.

If you only have one floor section, the rear
wall may now be directly attached to these
short sides.
Step 5
Attach Side Extensions and Rear Wall:
The rear half of the building can now be constructed. Position the rear wall of the building near the back edge
of the platform. The remaining side extensions can now be attached to each edge of the rear wall. Use 3/8”
bolts with two washers per bolt. Two bolts are required for each side extension.

Step 6
Attach Front And Rear Sections:
Join front and rear sections together. Use
3/8” bolts with two washers per bolt. Two
bolts are required at each joint.
Skip this step if you only have
one floor section
Step 7
Attach Walls to Floor:
After drilling a 1/4” pilot hole, use a 5/16”
lag bolt with washer in each hole.
Position front, rear, and side walls so that they are centered and aligned to the floor. Because of the
wood posts on the front, the front will be a little wider than the rear. Use the holes that are provided on
the bottom edge of each panel as a guide for drilling 1/4” pilot holes through the flashing and into the
base. Use a 5/16” lag bolt with washer in each hole.

Step 8
Attach Front and Rear Roof Peaks:
Screw in from top
Screw in from rear
Start with the rear roof peak. Sit it on top
of the rear wall such that the downward
pointing flap with the mounting holes is
against the rear panel. Make sure it is
centered with equal overhang on each side.
Attach with rubber sealed self drilling
fasteners. Make sure that the peak does
not shift to one side or the other during
drilling.
The front roof peak with coloured flashing
can now be installed as shown. Use the
same rubber sealed self drilling fasteners.
The fasteners pass through and hold both
the flashing and peak. Small pilot holes
are located on top of the front panel to
properly locate the assembly.

you only have one floor section
Step 9
Attach Roof Support Beams:
The main roof support beam has small slots cut into each
side. The slots allow you to insert the beam into the roof
peaks. Install as shown. The steel support beam is then
draped over the main support beam. The ends of the
beam have small flaps that must be bent out to allow for
attachment to the top edge of the container sides (see
inset picture). Do not attach the beam until step 10

Step 10
Install Front and Rear Roof:
The front and rear roof sections are identical. Install the front roof section first. The drip edge with
the notch will be towards the front. Align the holes on the front edge of the roof with the pilot holes
on the the top of the front roof peak. Use the rubber sealed self drilling fasteners. Move the steel
roof support beam so that the pilot holes along the top of the beam line up with the slots on the
rear edge of the front roof section (do not attach).
Slots in roof will overlap in middle

front and rear
The rear roof section may now be installed. Install in the same way, starting
with the fasteners along the rear roof
peak. If some of the holes do not line
up, you may need to lift one of the rear
corners of the building until they do line
up. This may be accomplished by
inserting a 2x4 under the appropriate
corner and lifting until the holes align.
Only one roof section is supplied if
you only have one floor section
The slots on both roof sections, and the pilot holes on the top of the steel roof support beam should
now line up. Before you install the rubber sealed self drilling fasteners, lift the rear roof up
slightly (1/2” or so) and hold it up with some shims. A line of silicone should then be injected
into the gap. Remove the shims and screw down the roof. You can now go inside the shed to
attach the steel roof support beam to the top edge of the side walls (picture step 9). Use the self
drilling fasteners without the rubber seals.
Your container has internal channels at the botton of each wall to help direct water into the
corners and out of the building. If you wish to prevent water from getting into these channels
in the first place, you should silicone the small gap at the bottom where each corrugation
meets the floor. Leave the tops open for ventilation.
TIP - This container is designed to provide enough ventilation to prevent humidity buildup. In locations where
the container may be exposed to a lot of fine blowing snow, you may wish to close off the vents incorporated
into the front and rear roof peaks. Aluminum foil tape (or similar) can be used.
The Container is now ready for use.
Please review the safety instructions on the next page.
