measure from here When measurements are given for a board
length, it is from the longest side.
Always wear safety glasses when cutting or nailing!
The siding is made in 4x8 sheets with grooves
cut into the face, the long edge is beveled so
that the siding overlays where they butt.
To identify which edge we want you to use, we
will refer to the edge as either the 'LAP' Edge
or the Tongue Edge. Nail siding with 6d galv.
nails, spaced 12" apart.
IMPORTANT INFORMATION - Read This First
Thank you for your purchase. I want you to be completely satisfied with your building. The
2x4s are imported from Europe because they grade lumber four sides. If you are dissatisfied
with lumber you receive we will replace it.
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).
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. This will be a separate delivery.
Our kit does not include 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, then unscrew the top 2x4s. The bit for the screws is packed in the hardware bag. The
2x4s will be used for wall bracing and tie plates.
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.
Before building, obtain a building permit and check all pertinent building code regulations.

It is important that the floor be level and square.
Before nailing the flooring, measure the floor
diagonally (corner to corner). Then measure
the opposite corners. These measurements will
be the same if the floor is square (187-1/2").
2. Cut (10) ten 2x4-10' floor joist to 9'-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.
1. Treated lumber is not cut to exact length. Cut (2) two 2x4-12' boards to 12'-0".
Layout for 16" on center joist spacing. 'X' marks where floor joist will be placed.
Construction Details for Optional Floor System
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.
Material Description 10' x 12' Floor
2x4 Treated Headers 2 pcs. 12'

Flooring 5/8" 4x8 4 pcs. 4x8
8d Screw Floor Nails 1 lb. 8d
16d Galv. Box Nails 1 lb. 16d
If necessary use bricks, patio stones or similar material to level or provide additional support
to the floor. If your ground has low areas consider adding gravel and or 4x4 treated timbers
to rest the floor on. If you use 4x4 timbers you will need (3) three pieces 12' long.
3. Install the floor joist, over the 'X' marks, between the 12' long joist headers. Use 16d galv.
deck nails.

Step 4 Assemble Roof Trusses
Step 3 Assemble Front Wall Frames
1. Cut (2) two 27-3/4" long boards from (1) one 72" long 2x4 board.
2. Cut (2) two 72" 2x4s to a length of 69-1/2" used for header supports.
1. Place (2) two 62" long 2x4 boards with angled ends together as shown below. If possible,
hold in place with 2x4 blocks as shown. Make sure the trusses measure 10'-0" wide when
assembled to fit properly when installed.
2. Secure the tops together with a wood gusset. Nail the gusset to the 2x4s with (14) fourteen
6d common nails. Angle nail slightly so nails do not protrude through the 2x4 boards.
3. Repeat above steps to assemble (6) six more trusses.

2x4-62" Boards
Tip: If possible, temporarily screw 2x4 blocks to the floor. Short 2x4s, that may have an angle on
one end, supplied in the kit for this purpose. This will secure the truss boards in position so all the
trusses will be assembled the same. Use the 2-1/2" deck screws packed in the kit.

4. Install (2) two 72" long 1x3 trim boards, with top edge 3/4"
above door opening, along each side of the door opening. Use
6d galv. nails. Tack these boards with a couple nails; you may
want to move the trim later when you install the doors.
5. Install a 72" long 1x3 trim board centered across the top of
the vertical trim. 3/4" of siding will be revealed at top of door.

Step 18 Install Doors & Hardware
3. Before fastening the hinges to the side trim,
temporarily prop the doors in the opening. Leave
a space at the top and bottom of the doors and
between the doors and the side trim to allow
room for the doors to expand due to humidity.
If your door opening is out of square, the space
around the doors will not be even. You can
remove and re-position the side trim to make
allowances for this. The side trim does not have
to be flush with the frame of the door opening.
You can move the trim in or out to make the
door spacing equal.
4. Determine position of hinges and install to side
trim with 2" screws.
5. Installdoor haspon doubledoors.When properly
installed the hasp will fold in half to receive
locking latch and the screw heads will be
covered.
6. Install a barrel bolt on the lower back of
the door to secure this door in place when
closed. You will need to drill a hole for
the round shaft to drop into.
7. Install another barrel bolt at the top of the
door.

1. Locate the door that has a 2x4 fastened, on edge, to the
back side of the door. When doors are closed this 2x4 will
be in the center where doors meet. Lay the door with the
trim facing up and install (3) three 5" hinges to the right
side. To position the hinge properly, hold the rectangular
