Choosing the Right Type of Shed for You
Here are some of our most popular shed styles
All of our sheds are patio-friendly, perfect for placement on concrete, brick, or slabbed patio areas. As long as your patio is large enough for your chosen size of shed (we have some very large ones), you should be fine to commence with building.
Please bear in mind that if your patio is not completely level, an extra base may be required to give the shed a flat surface to stand on.
If you have wooden decking rather than a patio, check out this guide: Can I Put a Shed on Decking?
Need storage on a tighter budget? This range focuses on the essentials — practical space, sensible specs, and strong value. Even our lowest-priced wooden sheds still come with our 10-year guarantee, so you don’t have to compromise on peace of mind.
If you need to budget carefully, our selection of cheap sheds is where you want to look.
FAQs
Usually, no. Most UK properties are allowed sheds as 'permitted developments' with no planning permission required.
Exceptions (where you MIGHT need planning permission) include:
- Listed properties and locations of 'outstanding natural beauty'
- Structures exceeding 2.5 metres height on the eaves or, if placed near a boundary, 2.5 metres total height (our sheds don't exceed this)
- Sheds placed in the front garden
- Sheds exceeding more than 50% of the garden space
There are some other rules, so check out our guide to planning permission for sheds to get a full understanding.
Since 2020, we no longer have a physical showroom and all trade is conducted online. Our website shows previews of every size of building with precise measurements to make it easy for you to make an informed buying decision.
When you visit a product page, changing between sizes will immediately show you what the exact size looks like.
Each shed material has its own pros and cons and your decision should be based on how you intend to use the building.
Wooden sheds
Wooden sheds are the most popular type of shed, and for good reason.
- Pros:
- They look great and can be painted and customised
- They are very durable against wind and rain.
- Wood is naturally insulating against heat and cold.
- Cons:
- They are flammable. Not ideal for welding or other blowtorch work.
- They require regular maintenance, including treatment to prevent rot and insect infestation.
There are multiple styles of wooden garden shed available, including log cabin sheds. All our BillyOh wooden sheds are manufactured at our purpose-built site in the UK and come with a 10-year guarantee as standard.
Plastic sheds
Don’t underestimate the practical benefits of a plastic shed. They can serve you well for both storage and workshop uses.
- Pros:
- Plastic sheds are relatively inexpensive.
- Low maintenance and long lasting.
- Quality models offer solid durability.
- Not flammable.
- Cons:
- Difficult to customise without damage.
- Can’t be painted.
- Colour might fade with time.
Metal sheds
For a low cost, low maintenance garden building, look no further than a galvanised metal shed.
- Pros:
- Metal sheds are cheaper than wood and plastic sheds.
- They can be painted with specialist metal paint.
- Not much maintenance to do.
- Galvanised models are resistant to rust as long as the coating stays intact.
- Cons:
- Can be difficult to customise with add-ons.
- Metal sheds become hot in the summer.
- At less than 1mm thick, they can dent with impact.
We don’t currently offer a shed installation service. Our garden sheds are supplied for self-assembly and include full fitting instructions.
Delivery is available within Great Britain. Delivery charges can apply depending on your postcode zone — please see our delivery information page for full details.
When we say a 'base', we mean a surface that is:
- Flat (check with a spirit level)
- Solid (bricks, slabs or concrete. NOT soil, grass or gravel)
- With drainage (it doesn't have to be raised, but rainwater has to be able to leave the area.)
So yes, all sheds require a base.
It is important that a shed stands in a location where it will be able to easily remain upright without undue stress on the structure, and where it won't be absorbing water. Our wooden sheds all come with pressure treated floor bearers which raise the floor slightly above the ground, so you can place yours straight onto a level patio or reinforced decking without issue.
If your designated shed location is currently soft, you could level this out and use our Ecobase product to save you the work of landscaping.
The size of your shed depends on how you plan to use it. Whether you need space for tools, a workshop, or even a garden office, we offer sheds in a range of sizes to fit your space. Use our shed size guide to find the perfect match for your garden.
Our sheds are designed to be weather-resistant for UK conditions when correctly installed on a solid, level base and maintained as recommended. Protection varies by material and specification, so always check the product details.
- Wooden sheds: fitting the roof felt correctly (no gaps) is essential. Timber will naturally expand and contract, so keeping edges sealed helps prevent water ingress.
- Metal sheds: made from rust-resistant materials and designed for low maintenance, but correct assembly and anchoring helps keep them secure in high winds.
- Plastic sheds: low maintenance and good for damp conditions, with water resistance depending on the design and door thresholds.
If you need storage designed specifically for keeping contents dry, see our waterproof outdoor storage range.
Metal and Plastic Sheds: Yes. Because these materials are exceptionally lightweight, anchoring is essential. Without being secured to a solid foundation, these structures can be easily moved or tipped by strong gusts of wind. Most of our models include foundation kits or pre-drilled holes to simplify this process.
Wooden Sheds: Highly Recommended. While wooden sheds are heavier and sturdier, they are not immune to the "sail effect." High winds can exert hundreds of pounds of pressure against the side walls, leading to sliding, tipping, or structural "racking" (tilting).
- Heavyweight Sheds: Even for large, premium sheds, anchoring ensures the building stays square on its foundation, preventing doors from sticking and joints from loosening over time.
- Overlap & Small Sheds: For smaller sheds or those with lightweight cladding, anchoring is essential as they lack the mass to resist uplift during storms.
How Much Can You Fit in a 12x8 Shed?
Due to their large size, and especially the 8-foot width, there’s lots of potential for how you can utilise a 12x8 shed and what you can fit inside it. With such a large size, there are lots of options for what and how much can be put inside the shed itself. Bikes and garden equipment like lawnmowers and strimmers are an easy fit, as is garden furniture - with even bulky pieces like tables easily fitting through the double doors.
Is a 12x8 or 8x12 Shed Cost Effective?
This depends ultimately on how you intend to use the shed. If you’ve only got a small quantity of items to store which don’t take up too much space, a 12x8 may be too big for you - it may be more cost-effective to choose a 6x4 or 8x6 shed. However, if you need a large shed that can store large items or perform the function of a workshop, 12 x 8 present a good, cost-effective size.
What Features Do These Sheds Include?
Pent or Apex Roof Design
Our 12 x 8 sheds come across a range of designs, primarily focused on their pent or apex roofs. A pent roof is a more contemporary option, with a single slope for a smooth and modern look, while a traditional apex features two adjoining slopes and a triangular gable.
Wide-Opening Double Doors
Extra-wide double doors are a staple on these large sheds. We provide this to enable easy access, which is vital both for storing large and bulky items as well as enabling you to bring in heavy-duty equipment for craft or DIY projects.
Windowed or Windowless
Opt for ease of use or ultimate security with a windowed or windowless 12x8 shed. Windowed allows natural light to seep inside, which can help visibility if you’re working inside the shed for extended periods. A windowless shed, on the other hand, is more suited for security - hiding its content from the outside world.
Tongue & Groove Cladding and Guarantee
If you opt for a wooden model with tongue and groove cladding, you’ll be getting a shed with a robust outer structure and a smooth exterior seal that prevents moisture from getting inside. We offer a 10-year protective guarantee on all tongue & groove buildings to ensure you get a shed that stands the test of time.
