When compared to wooden structures, plastic sheds clearly aren’t a traditional design amongst the typical British garden aesthetic. However, they are becoming increasingly popular amongst homeowners and boast numerous benefits:

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.

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 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.
High-density polyethylene is known for its strength and durability, making it perfect for outdoor buildings. It is also a UV-inhibiting material, ensuring the shed won’t crack, peel, or chip. And, it is 100% recyclable and considered one of the most environmentally friendly plastics around.

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.

We offer a pay by finance option on any purchase over the value of £560.

Our simple finance options allow you to spread the cost of your purchase over 24, 36 or 48 months.Read more about our Pay by Finance option here.

Heavy-Duty Plastic Shed

This Lifetime product provides the perfect outdoor storage space for all your garden essentials. And, it looks great doing it! The plastic garden shed is a durable storage solution built using high-quality materials to bring you a robust, airy, and spacious garden building at an affordable price - and these are just some of the great advantages of plastic sheds!

High-Density Polyethylene

Polyethylene is our preferred plastic for building sheds because it is 100% recyclable and doesn't release harmful emissions during production. It is a modern and lightweight plastic that can easily stands up to the elements and requires none of the typical costs for protective treatments and very little maintenance - just a clean with some soapy water once in a while!

HDPE is also a Food and Drug Administration (FDA) grade plastic that includes premiere UV-inhibitors. This protects the shed against harmful UV rays, ensuring that it won't crack, chip, or peel - making it an ideal durable material for an outdoor storage building.

Steel Reinforcement

This plastic shed uses rust-resistant, powder-coated steel reinforcements to provide extra structural strength and protect the building against regular wear and tear - providing the ideal solution to harsh weather conditions.

Double Doors

The hinged doors to the shed open widely, so you can quickly move gardening tools, a lawn mower, and any other garden items in and out of the shelter. These doors also lock on the inside and outside, ensuring the security of your belongings at all times.

Weather Resistant

Adverse weather is practically synonymous with British weather. And so, for a shed to stand the test of time, it's got to be able to handle extreme weather conditions. Thankfully, this Lifetime Heavy-Duty Plastic Shed does just that. Whether it's a heatwave or heavy snowfall, this shed won't fade or crack.

Natural Light

If you want to treat your shed as a workshop, this model's light and airy feeling makes spending time inside the building all the more appealing. This brightness is achieved by the two windows and five skylights that let plenty of light into the room.

Apex Roof Garden Shed

The roof is apex shaped, which is preferable as it provides increased height in the centre of the roof where the slopes meet. This means you won't have to crouch when collecting your garden tools.

The plastic apex has the additional benefit of preventing water damage. The slopes ensure that efficient water drainage takes place.

Storage Space

The Lifetime 12.5x5 is a great medium-sized garden storage solution at a great price. And, while it might be one of the cheapest options, it doesn't lack quality, with more than enough room for all your garden equipment, tools, or even heavier items like bikes! 

Competitive Prices

All of this for a highly competitive price! This is a shed that will be the pride of your garden for years to come, continuing to look as fresh and sturdy as the day you bought it.
