This building is spray treated as standard

Spray Treated: Our sheds and summerhouses get a beautiful golden brown spray treatment before leaving the factory in order to preserve the quality of the wood. As this only lasts through the transit stage, we do recommend treating the wood after installation to protect it.

11mm: All sheds, excluding overlap, standard summerhouse, playhouses etc are made of 11mm thick cladding.

A tongue and groove roof and floor is included with this building.

Roof:

11mm T&G: 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 more premium look and feel.

Floor:

11mm: Our Standard flooring option which provides a durable and provides a solid foundation and underfoot to the building. The 11mm option is ideal for less demanding and frequent usage, suitable for lighter intensity purposes like summer houses and other living spaces containing light furniture. The 11mm tongue and groove timber makes this a solid yet suitable, economic option.

We'd recommend any flat and level base be put in place before you start construction of any of our buildings. The material can vary so long as it creates a flat and level base, many customers opt for Concrete, Paving Slabs or our popular Ecobase and EzeBase options available above. The floor of the building comes with bearers which lift the building off the base and allows the flooring to have a gap between itself and the ground this helps slow down or stop any rotting that could occur if the wood is kept in standing water.

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.

We do not offer an installation service on any of our buildings, our buildings are designed & made to be easy and simple to assemble. Using the assembly instruction included and with a team of just 2 people and a bit of DIY knowledge you can expect to have your BillyOh building up within a day, or as little as 3-4 hours with some of our smaller buildings.

Our summerhouses and sheds are delivered in easy to assemble panels. For your convenience the panels are no wider than 4ft so they can be easily maneuverable and fit through a standard doorway. Our Log Cabins arrive as individual boards that are designed to slot together.

Your order can be tracked through the account section on our website or by contacting us directly. You will be contacted after your order by our helpful care team to arrange delivery of your building.
