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, Hammer and a Drill with 2mm bit.

- Ensure there is plenty of space and a clean dry area for assembly. 

LOCATION FOR YOUR GARDEN BUILDING

A minimum of 60cm should be left around the perimeter of your garden building to allow access for 

maintenance, annual treatment and to allow air flow around the building.

Where possible you should avoid placing your garden building underneath large trees to prevent the tree 

causing damage to the building.

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. 

Once your garden building has been installed it will need to be treated as soon as possible and annually to 

prevent the timber from deteriorating and to waterproof it. This is required to maintain the anti-rot guarantee. 

Dip Treated buildings - Require a preservative treatment to protect against rot and decay and a waterproof treat-

ment to prevent water ingress

Pressure Treated buildings - Require a waterproof treatment to prevent water ingress

Log Cabins - Are supplied untreated and require a preservative and waterproofing treatment.

BUILDING A BASE

When thinking about where the building and base is going to be constructed: 

Ensure that there will be access 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 the case of childrens 

products independently tested to EN71 level, we cannot accept responsibility for your safety whilst erecting or 

using this product.
