Whilst our playhouses are delivered undecorated with the natural wooden surface, encourage your little ones to paint and splash some of their favourite colours so that they can have a colourful play den. There are so many ways to make your little ones’ playpen more homely and colourful looking. A variety of colours can be purchased as an optional extra with your playhouse.

This log cabin playhouses use 19mm tongue and groove log boards, these boards interlock with each other for extreme strength and durability, this construction provides the building with excellent weather protection.

All of our playhouse also come as complete buildings with floor, roof and felt included. This building comes with 11mm T&G roof and floor as standard.

Aside from their wooden assembly, our children’s playhouses also come with premium mineral felt roofs. It provides superior protection and durability to these outdoor structures’ roofs.

Our playhouses are not designed for children aged under 36 months as there are many small parts, which may be a potential choking hazard. Furthermore, there is often a maximum user weight of 50kg when tower playhouses and two-story playhouses are concerned. We also recommend keeping the playhouses a minimum of 2m clear from any obstructions or other structures.
Our playhouses use shatter-resistant plastic (SAN). SAN is used for its UV properties and the tougher finish avoids breakages, when compared to the properties of glass shattering.
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.
