Browse our plastic sheds for sale — the lowest-maintenance way to keep garden tools, bikes and equipment safe and dry. Our models are made from durable plastics including vinyl (PVC), polypropylene and HDPE, so every shed's outer cladding is immune to rot, rust and decay and needs zero annual treatment, unlike timber.
Lightweight and quick to assemble, many feature polycarbonate windows or skylights for natural light, and some add a reinforced metal frame for extra strength. They're part of our wider garden sheds range — and if you're not sure which option suits you, read our guide on how to choose a shed.
FAQs
Plastic sheds have an extended life compared to other sheds - especially those which are well looked after! Because plastic is impermeable, it can keep out rain, snow and ice, whilst also being immune to rust, mould and corrosion. As long as they’re looked after, barring some major incident, there isn’t anything that should affect your plastic shed except general deterioration over a long time. Our BillyOh plastic sheds also come with steel reinforcement and metal hinges, making each design sturdy and built to last.
At Garden Buildings Direct, 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. Moreover, because the material itself is lightweight, plastic sheds also require little manpower to install. You and a friend can have it built in no time.
Because garden buildings such as sheds aren’t naturally heated, internal condensation can be an issue, particularly in the colder months of the year. Plastic sheds can suffer from condensation, but only when dampness is present. Because the air inside the shed is generally slightly warmer than the air outside, any moisture in the foundation base will rise until it reaches the cold roof panels.
A base for your garden shed should be more than sufficient in tackling this potential issue, whether it be a timber base, concrete, paving slabs, or a prefab base kit.
While plastic sheds won’t rot or rust like wooden or metal alternatives, we still recommend placing them on a firm, level base. A proper foundation helps prevent sinking on soft ground, ensures stability, and reduces the risk of panels becoming misaligned over time – especially if the ground is uneven.
Some BillyOh plastic sheds include a built-in floor, while others come with a floor framing kit designed to be filled with timber or another solid material. In either case, preparing a level surface such as paving slabs, concrete, or a timber base will make installation easier and extend the life of your shed.
This is determined by the individual shed, with some offering built in floors and some electing not to. At Garden Buildings Direct, each of our plastic sheds specifies whether or not a floor is included, in order to provide maximum clarity concerning this.
Plastic sheds don’t particularly like extreme temperatures - it can cause discolouration and even cracking in the worst cases. Luckily, in the UK, these temperatures at either end of the spectrum are rarely reached, so this issue is minimised. However, in direct heat, plastic sheds can become warm, and in the extreme cold, the plastic can contract, so be sure to keep an eye on your plastic shed when severe weather conditions are present.
If your shed is a place you intend to use or store items in throughout the year, then insulation is definitely worth considering as a relatively inexpensive means of allowing your garden shed to better regulate and maintain internal temperature. However, while the majority of wooden sheds can be insulated to better retain heat in the colder months, plastic sheds are generally not designed to be insulated. If you want to learn more, check out this guide to insulation and damp-proofing.
While plastic sheds are generally lightweight, they can still offer a good level of security, especially when anchored properly. Many of our BillyOh plastic sheds come with lockable doors and strong metal-reinforced frames, helping to keep contents safe. For enhanced security, we recommend placing your shed on a solid, level base and using padlocks or internal locking systems where available.
Both metal and plastic sheds offer an alternative to wooden sheds as well as a price-friendly option. Both are made from long-lasting and durable materials. However, a metal shed may be able to support more weight for things like shelving and hooks. Both offer fairly lightweight options that can also potentially be repositioned if necessary.
Why Choose a Plastic Shed?
- Weather-Resistant: UV-resistant plastic panels stand up to rain, frost and sun without swelling, warping or fading the way untreated timber can.
- Low Maintenance: There's no painting or preservative treatment. An occasional wash down and a check of the fixings is usually all a plastic shed needs.
- No Rot or Rust in the Panels: The plastic walls and roof won't rot, and they won't rust. On steel-reinforced models, the frame is the only metal part.
- Secure Storage: Many models have lockable doors, and some add a steel-reinforced frame for extra rigidity.
Plastic Shed Sizes: What Fits Inside?
Floor size tells you how much a shed holds, but the door opening decides what you can get through it. Check both on each product page before you buy, and measure the bikes, mower or furniture you plan to store.
Compact Plastic Sheds: 6x3ft, 4x6ft and 4x8ft
Slim footprints for side returns, patios and narrow spaces, including a 4x8ft lean-to design that sits against a wall. The 6x3ft model is under a metre deep, so it suits long-handled tools, hoses and folding chairs. Single doors of around 75cm take a push mower but not wide items. At 2.3m deep inside, the 4x8ft lean-to has room for an adult bike stored lengthways. For more compact options, see our small storage sheds.
Medium Plastic Sheds: 6x6ft, 8x5ft and 8x6ft
Space for a mower, garden tools and equipment together. The 8ft models give you a back wall of around 2.3m, long enough to store adult bikes, which are typically around 1.7–1.8m long. Most models in this size have double doors between 1.2m and 1.55m wide, so you can wheel things in without turning them on end. The exception is the Jasmine 8x5ft, which has a single 75cm door.
Large Plastic Sheds: 8x7.5ft, 8x10ft, 10x8ft and 10.5x8ft
Room for bikes, a mower, garden furniture and shelving, with a walkway between them. Double doors from 1.42m to 1.54m wide make it easier to move bulky items in and out. Ridge heights of 2.3m to 2.44m give standing room in the centre, with eaves at around 1.8m along the walls. The Lifetime models include a built-in plastic floor.
Height and Planning
Every plastic shed in our range is under 2.5m at its highest point. That's the height limit for outbuildings within 2m of a boundary under permitted development in England. Other conditions also apply, so read our planning permission guide before you choose a spot. If you're tall, check the door height: several of our smaller models have doors under 1.6m.
Some models come in more than one size, so check each product for options. If you're short on space, take a look at our small storage sheds.
Vinyl, Polypropylene and HDPE Sheds
Our range uses three types of plastic: vinyl (PVC), polypropylene and HDPE. All three are UV-resistant, and none of them absorbs water like timber. Our heavy-duty models, including the Lifetime range, pair thicker panels with a steel-reinforced frame to make the structure more rigid. Check each product's specification for its materials, its floor and what's included.
Plastic Sheds vs. Wooden and Metal Sheds
Compared with wooden sheds, a plastic shed needs less upkeep. Timber needs regular treatment to resist rot, while plastic panels need no preservative at all. Metal sheds are low maintenance too, and they're generally better at holding heavy shelving and wall hooks. Plastic, on the other hand, can't corrode where it gets scratched, and it's available in finishes that look less utilitarian.
Design and Assembly
Appearance: Many models have woodgrain-effect panelling in neutral colours such as grey, and selected models add faux-shingle roofing for a more decorative finish.
Lightweight Panels: Plastic panels are lighter than timber, so they're easier to carry into the garden and handle during assembly. Most models can be taken apart and rebuilt if you move house or rearrange your garden.
Running Costs: With no preservatives to buy and no yearly treatment to schedule, a plastic shed costs less to keep up over its life than a timber shed of a similar size.
