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

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 spiral floor 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.

4. To provide additional strength, install (2) two rows of 2-1/2" wood screws spaced 16" apart
as shown below.
5. Repeat steps to assemble a second Loft Beam.
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 (10) ten 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 with a brush to the top surface.
3. Locate (2) two 72" long 2x6 boards with a notch on one end. Install these 2x6 boards
over the bottom boards as shown.

4. Secure the 2x4s at the peak with a 12" x 32" wood gusset. Apply wood glue with a brush
between the gusset and truss and nail with (25) twenty-five 6d common nails evenly spaced.
5. Turn the truss over and install a gusset to the other side of the truss.
6. Repeat this process to assemble (6) six more trusses.
32" Top Gusset
1. Position a Gable Plate (from Step 2) on the floor with the narrow edge side down.
2. Position (2) two truss halves (2x4s connected with a metal plate) with the short legs against
the end of 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. See detail below.
3. There are short 2x4s, that may have an angle on one or both ends. Use these as a jig to hold
the truss halves and gable plate together by temporarily screwing or tack-nail blocks to floor.
This will ensure that the trusses and gable ends are identical.

Building Tip: Gather all pre-cut gable siding and position them on
gable frames before nailing.All siding should extend 3/4" below Gable
Plate. If siding extends above frame cut siding flush with frame.
1. Select a siding panel with a 'Tongue' edge and install on right side of gable. Before you install
the center siding panels ,lay them on the frame and trace the top and side of the door opening
on the siding panels. Cut panels from bottom of siding to top of door opening. Save these
pieces to be installed on loft doors below.
Step 5A Apply Siding to Rear Roof Gable
2. Select the siding panel with a 'Tongue' edge
on right side. Install this panel on left side of
gable. Use 6d galv. nails spaced 8" apart.

corrugated fasteners. Place the doors on level surface
with fasteners facing up. Re-cut the siding from step 1
to the size of the door frame. Place primed side down
and secure the siding panel to the frame with 1" screws.
Set doors aside. They will be installed in a later step.

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' below.
Nail bottom gable to loft flooring. Use 10d
sinker nails spaced evenly in stud openings.
2. Install (2) two 61" long 1x4 gable trim flush with the top edge of the gable. Install the
ends with blue marks together. Install trim with 8d galvanized nails spaced 12" apart.

location of the first truss. The last truss space will be more than 24".
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.
Step 18 Install 2x4 Truss Plates
1. Install a 48" long 2x4 truss plate against the rear gable
and flush with outside edge of wall plate. Install a 72"
long 2x4 truss plate. Cut another 72" truss plate to size
and install. Use 10d coated sinker nails spaced 16".
2. Repeat to install truss plates on the opposite side.

Soffit Board Flush With Siding
To prevent the nails from protruding
thought the bottom of the soffit board,
nail at an angle when nailing roof
sheathing to the soffit boards.
1. Place trusses over the 'X' marks and secure
trusses to 2x4 truss plate using 2x4 hangers and
10d coated sinker nails.
2. Locate 65-1/4" long soffit boards that have a
beveled edge. Install one of these boards flush
with the top of the siding and butting against
the rear gable trim. Secure soffit boards to the
top wall plate with 3" long screws spaced 8"
apart. Install the last soffit boards to fit behind
2x3 boards on the front gable.
Step 19 Install Trusses & Soffit Boards
1. Install a 42" x 72" OSB roof panel flush with
the face of the rear gable trim. Use a straight
edge to align the top of the sheathing with the
top of the truss. Continue adding sheathing
following the layout on the next page. Use
7d coated sinkers, spaced 6" apart.
2. Repeat step for opposite side.
