General Instructions
BEFORE YOU START PLEASE READ INSTRUCTIONS CAREFULLY
- Check the pack and make sure you have all the parts listed.
- When you are ready to start, make sure you have the right tools at hand (not supplied)
including a Phillips screwdriver, Stanley knife, wood saw, step ladder and drill with 2mm
bit.
- Ensure there is plenty of space and a clean dry area for assembly.
TIMBER
As with all natural materials, timber can be aected during various weather conditions.
For the duration of heavy or extended periods of rain, swelling of the wood panels may
occur. Warping of the wood may also occur during excessive dry spells due to an interior
moisture loss. Unfortunately, these processes cannot be avoided but can be helped. It is
suggested that the outdoor building is sprayed with water during extended periods of
warm sunshine and sheltered as much as possible during rain or snow.
BUILDING A BASE
When thinking about where the building and base are going to be constructed:
Ensure that there will be access (60cm) to all sides for maintenance work and annual
treatment.
Ensure the base is level and is built on rm ground, to prevent distortion. Refer to
diagrams for the base dimensions. The base should be slightly smaller than the external
measurement of the building, i.e. The cladding should overlap the base, creating a run
o for water. It is also recommended that the oor be at least 25mm above the
surrounding ground level to avoid ooding.
TYPES OF BASE
- Concrete 75mm laid on top of 75mm hard-core.
- Slabs laid on 50mm of sharp sand.
Whilst all products manufactured are made to the highest standards of Safety and in
the case of childrens products independently tested to EN71 level, we cannot accept
responsibility for your safety whilst erecting or using this product.
Refer to the instructions pages for your specic product code
For ease of assembly use a
rubber mallet to t the log
boards. Do NOT use a heavy
hammer.
Ensure to measure and check before cutting
boards.
It is advisable to use a hand
saw when cutting roof and
oor boards.
To ensure log boards are even, use a spirit
level to check each layer has been installed
correctly.

ers and place a space of 2mm to
ensure every roof board lines up
with the truss’.
*Ensure the roof boards meet
at the top of the apex and leave
an overhang at the bottom.

along the roof, xing each one into
position using 3x40mm screws,
making sure that each board is
interlocked, ush at the bottom &
meet at the top of the apex.

will overhang: Using a staight edge
and a pencil mark out a line as
a guide.
Cut along the pencil mark and
remove the excess. Place the
cut down boards back onto the
roof and secure into place
using 3x40mm screws per
board.

board on one side. Continue adding
the oor boards (internally) making
sure to interlock each individual board.
*Do NOT secure the boards until
the last board has been measured
and cut.
Following the same method as before
measure the gap between the bottom
of the tongue (on the last board placed)
and the log board.
Using a straight edge mark out the
measurement onto the last oor board
(No. 15) and cut along the length
removing the excess.
**Please note: Mark the nal board
2mm under the measurement; This will
allow the timber to expand and
contract correctly.
Once all the oor boards are in position
secure each board into position using
8x40mm screws.
