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. 

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 guaran-

tee. 

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

treatment 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.
