IMPORTANT INFORMATION ABOUT YOUR SHED KIT
To identify which edge we want you to use,
we will refer to the edge as either the 'LAP'
Edge or the Tongue Edge.

Download the most current instruction book at www.barnkits.com; use the "manuals"
link on the menu bar and then select your building kit and size.
Thank you for purchasing our shed kit. Read the instructions before starting the assembly
of the building. If you have any questions about assembling the kit, call 800-245-1577.
Business hours (8:00-5:00 ET) Monday thru Friday. After business hours call 724-866-
HELP (4357) or email to [email protected].
The material that is included in our kit is listed on the back page. The optional floor package,
if purchased, will be supplied by a local lumber supplier.
Our kit does not include the shingles, the quantity needed is listed on the back page. The
siding is primed. You will need to apply a finish coat using latex acrylic paint.
Some of the framing lumber was used in the shipping pallet. Unpack the material from the
pallets. Unscrew the OSB panels and the 2x4s from the shipping pallet. The 2x4s will be
used for wall bracing and to support the loft beams. The bit for the screws is packed in the
hardware bag.
Most buildings are installed on a wood floor and the siding was designed to extend over the
wood flooring. If the foundation is a concrete floor cut the siding flush with the bottom of
the wall plate to prevent the concrete from contacting the siding.
Stacking the boards, according to size, will make them easier to find when needed. Do Not
discard any material until your building is complete.
Before you begin construction, be sure to study this assembly manual. Also, obtain a building
permit and check all pertinent building code regulations for your area.
Thank you for your purchase. Bill & Linda Rinella, owners

1. Stagger the 4x4 timbers as shown below. Cut (2) two 2x4- 8' boards into 2' long blocks
to secure the 4x4s where they butt together.

Rear Floor Section
4. Install the floor joists cut above between the 8' joist headers. Secure with 16d galv. deck nails.
5. Place floor assembly over the 4x4s. Square floor assembly. Measure the floor diagonally
(corner to corner) and then the opposite corners; these measurements will be the same when
the floor is square. Toenail frame (headers & joists) to the 4x4 runners.
2. Cut (2) two 2x4-8' to a length of 8' -0". They
will be used for the joist headers. Layout, from
left, for 16" on center joist spacing. 'X' marks
where floor joist will be placed.
6. Cut (2) two 2x4-12' to a length of 12' -0". Layout
for 16" joist spacing, See above.
7. Install floor joists between the joist headers. Square
the floor section and install against the section
assembled above. Toenail to the 4x4s runners.
8. Install 4x8 flooring over the 2x4s. Use 8d

Foundation size is 12'-0" x 20'-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.
Constructing Details for Deluxe Floor System
Deluxe floors include 4x4 runners, standard floors do not.
3. Cut (17) seventeen 2x4-12' treated boards to 11' -9". These will be the floor joists. 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.

Step 2 Assemble Gable Plates
1. Butt (2) two 72" long 2x4s together and secure them by nailing a 3-1/2" x 42-3/4" long
plywood gusset across the top where they butt together. The gusset needs to be centered
on the 2x4s (approximately 50-5/8" of the 2x4s will be exposed on each side of the gusset).
Use wood glue and (2) two rows of (20) twenty 6d common nails to secure the gusset.
Step 1 Assemble Loft Beams
1. Locate (2) two 36" long 2x6 boards with a notch on one end and a 2x6 board without a
notch. Position these 2x6 boards on a flat surface as shown below.
2. Apply a coat of glue to the top surface using wood glue supplied in the kit.
3. Locate (2) two 72" long 2x6 boards with a notch on one end. Install these 2x6 boards
over the bottom boards.

4. Nail a 31-3/4" long 2x3 block where the trusses meet at the top with 10d coated sinker
nails. Secure with a 32" wood gusset. Apply wood glue between the gusset and truss and
nail with (25) twenty-five 6d common nails.
5. Turn the truss over and install a gusset to the other side of the truss.
6. Repeat this process to assemble (8) eight more trusses.

1. Position a Gable Plate (from Step 2) on the floor with the narrow edge side down. Use 2x4
blocks to hold the 2x4 plate straight.
2. Position (2) two truss halves (2x4s connected with a metal plate) with the short legs against
the 2x4 Gable Plate Assembly. DO NOT attach the Gable Plate Assembly to the truss. It is
temporarily used to help hold the 2x4 truss parts in place and will be attached in a later step.
3. Secure 2x4 blocks around the perimeter of truss to hold truss parts in place.
Do Not Fasten Truss Legs to Gable Plate

8d galvanized box nails along the gable plate and
6d galvanized box nails on studs and truss frame.
Space nails 8" apart.
The rear gable trim is installed
in Step 18, however you can
install the trim now.

2. Install (7) seven 80-1/4" long wall studs between the wall plates. Use (2) two 10d sinkers
at each end of stud. Nail the frames together with (5) five 10d sinkers, alternating sides.
3. Repeat to assemble (3) three more 10' long sidewall frames. You will need to cut (2) two
64" long 2x4s to a length of 48" to assemble the last 48" wall frame.

2. Square the wall frame. Install a full width siding panel using 8d galvanized box nails spaced
8" apart. Do Not nail along the long edge that overlaps the 10' wall frame. You can nail
this edge after the wall panels are installed. This will enable you to separate the wall panels
making them easier to handle.
Do Not Nail Along This Edge

2. Install the rear 2x6 beam 84" from the 2x4 joist header boards with the 'X' marks on the beam
facing the back wall. You can use a 2x4-7' board as a gauge to properly space the beam.
Refer to Step 15 to see how the loft floor joist will be installed.
Place the notch under the top plate and support the beam with one of the 76-1/4" long 2x4s.
Further secure the beam with a 2-1/2" wood screws through the top of the wall plate.

1. Install the rear gable on the rear wall. The
siding on the gable must extend over the 1x4
trim board, not behind it. See detail 'D' on
next page. Nail bottom gable to loft flooring.

Important: When marking the opposite wall, place the 'X' mark on the same side of the line
so your trusses are parallel when they are installed.
1. Install a 72" long 2x4 truss plate against the rear gable
and flush with outside edge of wall plate. Install a 64"
long 2x4 truss plate. Cut another 64" tie plate to size
