Our Standard flooring option which provides a durable, solid foundation and underfoot to the building.

19mm Tongue and Groove

1.7 times thicker than our standard 11mm flooring, our premium floor is the perfect choice for higher intensity usage. The construction uses thick 19mm Tongue and Groove timber, which gives you not only the strength, but better insulation against the cold weather. This specific floor is the perfect option if you’re planning on using the building as an everyday use office, gym or games room with heavy objects.

Our standard roof option, this interlocking roof provides a reliable covering for any building. The Tongue and Groove not only gives your building a stronger roof but also a premium look and feel.

Created from toughened glass, the double glazing is the ideal option for a building which is used all year round. The extra thickness will provide better insulation and keep your building warmer in those colder months of the year.

Untreated: Our log boards are delivered to you as untreated. Not only does this provide you with a lodge appearance, but allows you to decide the treatment type and colour which suits your tastes. You will need to treat this annually and after assembly to protect your wood against rot, decay and insect infestation.

Pressure Treated: For an extra level of protection, you can opt for pressure treatment which is an effective way of keeping the wood long lasting. This is an extra step in the manufacturing process where the wood is treated in a pressurised tank. Chemical preservatives are forced deep into the wood’s fibres to resist rot, decay and termites. When you upgrade to Pressure Treatment, the guarantee is extended from 10 to 15 years.

Yes, all garden buildings should be assembled on a firm and level base. A base will ensure your building has a solid, long-lasting and well-drained foundation.

Our robust and simple to use EcoBase provides you with a firm, long-lasting foundation with suitable drainage for your garden building. It is quick and easy to install through the use of snap connectors that link the grids to each other.

With the Dorset S an 11mm tongue and groove floor and roof is included but you can upgrade to 19mm to suit more intensive use.

If the building is shorter than 2.5m tall you should not require planning permission, (unless it’s more than 50% of your garden or to be put in your front garden). Planning permission rules can vary by area so we would strongly recommend checking your local council rules before ordering from us.
