Please Note: The price of this item includes full installation of the building into your garden. A firm and level base is required for this, either made of solid concrete or concrete slabs. It is recommended that the floor of this garden room is further covered by either carpet or laminate to reduce wear on the matchboards.

In order to qualify for our 10 year anti-rotguarantee the building must be annually treated with a high quality spirit based wood preservative.

Important Information

Unless otherwise stated, our buildings are supplied flat packed as DIY kits with full instructions.

Buildings with styrene windows - our styrene windows are protected using a clear film which will need to be removed after you've installed the building.

It is the customer's responsibility to follow the instructions outlined in Aftercare.

All of our buildings are delivered unpainted. The buildings are dressed for display, we don't supply any accessories or shelves featured within the product images.

Exact product dimensions are supplied on the listing as we do round off the main size of the building in order to make it easier for customers to find, so please be sure to check the item's specific measurements carefully.

All measurements refer to the exterior of the building which includes the roof overhang unless stated otherwise.

We also would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third party costs.

Delivery times highlighted with an asterisk (*) refer to working days.


IMPORTANT: This product comes untreated, to allow the customer to finish with a colour/shade of their choice. Once installed, it will need treating as soon as possible on an annual basis in order to receive the 10year anti rot guarantee. The building also includes a 1 year manufacturers guarantee as standard.

If your building is fitted with styrene windows, they are protected using a clear film which will need to be removed after you've installed the building.

Planning Permission

This is in no way binding and is dependent on Local Authorities, but may be used as a guide

Applications for approval normally involve a fee, normally related in some way to the value of the development.

Where the development is more than just a simple extension, it is worth considering employing an architect to draw up the plans, submit them to the Local Authority, obtain the approval and then to oversee the work. A professional architect will have professional insurance in case anything should go wrong and should know the Local Officials and their particular foibles.

Every application for Planning Permission or Building Regulations is, to an extent, unique. While the following are general rules, it is impossible to define all the regulations applying to a specific development - Local Authorities have some thick books of rules rather than just these few pages. It is always good advice to consult your local planning/building control officers early to avoid any costly abortive work. If work is carried out without the necessary approvals, the local authority can issue an enforcement notice requiring (at best) retrospective approval or (at worst) demolition of the work completed.

Although the functions of Planning Officials and Building Inspector are separate, the two will often be found in the same building; they are normally very helpful and offer authoritative guidance.

Normally Planning Permission or Building Regulation approval is not required provided that:

• Sheds and greenhouses do not cover more than half of the area of the garden; not including the area occupied by the house.

• It contains no sleeping accommodation and the floor area does not exceed 15 square metres.

• No point is less than one metre from a boundary.

• It is not more than 3m high for a flat roof, or 4m with a ridged roof.

• Overall height from ground level to ridge must not exceed more than 2.5 metres within a 2 metre range of any boundary. A building with overall height exceeding 2.5 mtrs in height and placed within 2 metres of any boundary will require planning permission.

• Height of the eaves must not exceed 2.5 metres

• No part projects beyond any wall of the house that faces a road.

• The outbuilding is for use only by those who occupy the house.

• A Log Cabin should be more than 5 metres from the main dwelling and up to 50% of the remaining garden can be utilised with this type of building.

• No verandas higher than 30cms from ground level.

Building Regulations do state that structures built of combustible material (i.e. a wooden shed) must be at least 2 metres from the main house.

If at all in doubt contact your local authority for clarification. No charge will be made if no planning permission is required.
