What is required from you

  • Easy access to the installation location

    Please make sure there is adequate access to the build site without the need to go through your house, garage or neighbouring property.

  • At least 60cm around the building site

    The installation team require approximately 60cm (2 feet) around all sides of the site of the building to allow for safe access.

  • A firm and level base

    In order to have a long lasting building, you must ensure there is also a level base ready for the building to sit on. This can be concrete, slabs, or a pressure treated wooden frame and must be no bigger than the size of the building.

  • Treat your building after the installation

    Once your garden building has been installed it will need to be treated as soon as possible with paint, preserver, stain or oil. This will need to be repeated annually to prevent the timber from deteriorating and to waterproof it.

  • You will be required to build the base for your structure ahead of installation.

Building a base for installation

  • Preparing your base

    Forest buildings need to be installed on a pre-prepared level base with no slopes. Buildings cannot be installed on grass, soil, loose gravel or other loose material surfaces.

  • The importance of a level base

    Any base that has a slope larger than 15mm from edge to edge will cause twisting, creating gaps in the sections and the roof, doors & windows.

    To check that your base is level, place a straight edged piece of timber across the length of the base and place a spirit level on top of the timber near the centre. The bubble in the spirit level should sit comfortably within the 2 centre lines. Repeat the process across the width of the base. Forest may request photos of the completed base prior to booking an installation date.

    Ensure there is sufficient space around all 4 sides of where the building will be. The installers will need at least 2ft around all sides to complete the installation.

  • Suitable bases

    CONCRETE: By far the best material for any size base to be constructed from. A concrete base should ideally sit on a good dressing of sharp sand and hardcore to allow for adequate drainage of rainwater

    CONCRETE SLABS: Concrete slabs are the next best alternative to a concrete base. The slabs should be laid in such a way to form a continuous base with no large gaps between each slab. As with a concrete base, a concrete slab base should ideally sit on a good dressing of sharp sand and hardcore to allow for adequate drainage of rainwater.

    View all concrete slabs.

    View all sharp sand.

The day of installation - please make sure:

  • All vegetation is cut back prior to the installers arriving to allow for a successful build.
  • There is suitable access to the installation site without having to enter your property.
  • The base has been made to the correct size to fit the shed, is level, and there is at least 2ft space around all sides of the building.
  • There are adequate parking facilities for the assembly team’s vehicle and any necessary parking permits have been secured.
  • There is someone at the property for the entire time of the installation.
  • The building has been placed as close to the build location as possible.
