Frequently Asked Questions


  • Maintenance free - One of the biggest positives surrounding plastic sheds is that they require virtually no maintenance. They’re easy to clean, not prone to rust or rot, and don’t need to be kept painted in order to withstand extreme weather conditions.

  • Highly portable - Thanks to being lightweight and easy to disassemble, plastic sheds can be effortlessly moved if you decide to alter your garden layout.

  • Functionality - Plastic sheds are very functional garden buildings, courtesy of offering several potential uses. They can store plant food and fertiliser during the growing season, organise garden tools and much more.

We suggested that all garden buildings be constructed on suitable bases and flat, level ground. While a base isn’t needed to prevent rotting or rust over time in a plastic shed, good foundations can prevent your shed from sinking into the ground. Moreover, if your lawn isn’t level, building a shed of any material on top of it can lead to major issues concerning structural integrity in the future - something which a base can comfortably tackle. This building includes a foundation kit to provide a solid base for your shed and increase its structural stability.

If the building is shorter than 2.5m tall at the eaves you should not require planning permission (unless it takes up more than 50% of your garden or is to be put in your front garden). Planning permission rules can vary by area, so we 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 & manufactured 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 plastic sheds come in pre-assembled parts which are incredibly easy to put together. Assembling a plastic shed is a task which requires no special tools or building experience. In fact, many modern plastic sheds can be simply snapped together.

Attractive Rustic Style

The beautiful rustic style of this Lifetime Shed is sure to dazzle in any garden. The exterior and features of this shed have been crafted to have a rustic, cottage-like appearance.

Spacious Storage

At an impressive 20ft x 8ft, this huge Lifetime Shed is the biggest plastic model we offer and offers a tremendous amount of storage. There's enough storage space for all the garden equipment you could wish for, and then some.

With the wide-opening double doors, the Lifetime is also the perfect solution for storing bikes, lawn mowers, and heavier tools and equipment like ladders or even garden furniture. Install shelves, hooks, and racks to add space-efficient vertical storage. If you prefer, there's enough space in this shed for a little workshop.

Strong and Durable Design

You can rely on the Lifetime Shed to provide strength and long-lasting use. While the exterior material is plastic, this shed is supported throughout its structure with steel reinforcement trusses. You can find these supports in the roof, walls, and even the doors - providing security and reliability to the shed.

Plastic Garden Sheds can have a poor reputation for their durability. But with the Lifetime, there's no need to worry. The plastic panels are made out of High-Density Polyethylene (HDPE), which is fully weather resistant and durable - perfect for outdoor storage. The Lifetime will easily withstand anything the British weather throws at it.

Useful Features

On top of all that, the Lifetime still has a few tricks up its sleeve. First is the built-in PVC plastic floor, which makes the shed a complete unit once built. There's no need to invest or build a floor yourself, just make sure the shed is built on level ground!

Security is also accounted for with padlock holes built into the doors as standard. And don't worry about rot or moisture accumulating in the structure either - there are vents on either end of the shed to provide air ventilation and stop dangerous moisture buildup.
