Winter = High Moisture = Expansion

Summer = Low Moisture = Contraction

All buildings should be 

erected by two adults

For ease of assembly, you 

MUST

 pilot drill all screw 

holes and ensure all screw 

heads are countersunk.

CAUTION

Every effort has been made during the

prospect of splinters on rough surfaces of the 

timber.  You are strongly advised to wear gloves 

when working with or handling rough sawn 

timber.

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 affected 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 firm 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 

off for water. It is also recommended that the floor be at least 25mm above the 

surrounding ground level to avoid flooding.

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
