Shed Buying Guide: Choosing the Best Garden Shed

A proper shed buying guide is essential before you get into the world of treated timber, roof types, and flooring options. One wrong decision can leave you with a shed that leaks, warps, or struggles to survive a British winter.

Not every shed on the market is built to last, and the differences between materials and designs aren’t always clear until it’s too late. Whether you're after extra storage, a workspace, or a spot for your tools, it’s important to understand what actually affects durability and performance.

From cladding thickness to door security, small details make a big difference. This guide walks you through what to look for, so you can choose a shed that suits your garden and stands the test of time.

HOW TO CHOOSE A SHED

There are several factors to consider when choosing a garden shed including what you intend to use the shed for, the space you have available in your garden, the material and the size.

Intended Use

The purpose of your shed determines everything from its structure to its setup. A shed used purely for storing tools has completely different requirements compared to one intended for relaxation or growing plants. Identifying the use from the outset avoids wasting money on the wrong type.
Here are some common uses of garden sheds:

1. Storage - a shed used to store garden equipment, bikes, or seasonal items must have internal space that can be structured easily.
2. Workshop space – sheds make great workspaces, providing both space to complete activities and for storing your tools.
3. Office space – a garden shed can work well as an outdoor office, providing quiet and comfort.

Material

Shed material affects durability, maintenance, and resistance to weather. Timber sheds provide a traditional look but need annual treatment to avoid rot and warping. Plastic sheds resist damp and are virtually maintenance-free but can feel less sturdy. Metal sheds offer the highest security but require proper anchoring to prevent movement during strong winds.

Size and Location

Choosing the right size is essential to avoid outgrowing the space too quickly. Placing a shed on level ground with easy access from the house and enough clearance for doors prevents future inconvenience. Following a reliable shed buying guide helps balance function, materials, and setup from the start.

Different Types of Sheds

Not sure what type of shed is best for your garden? From compact storage to stylish summerhouses, there’s a shed for every space and purpose. Here are a few different types to consider.

Wooden Shed

Wooden sheds are popular in UK gardens thanks to their natural appearance and ability to blend with the surroundings. They provide better insulation than metal or plastic, making them useful for storing items sensitive to temperature changes. However, untreated wood can suffer from rot, warping, and insect damage in the damp British climate. Regular treatment with wood preservatives is essential to protect the structure.

Metal Shed

Metal sheds are known for their strength and resistance to fire, pests, and decay. They are a secure choice for storing valuable tools or garden equipment. Adding vents or a moisture barrier can reduce humidity and protect stored items. A sturdy foundation and proper anchoring are also important, especially in areas exposed to strong winds.

Plastic Shed

Plastic sheds offer a low-maintenance option for garden storage. They are resistant to rust, rot, and UV damage, which makes them suitable for both rainy and sunny conditions. The smooth exterior is easy to clean, and many come with built-in ventilation to manage internal dampness. Some budget models may warp or crack in cold weather, so placing them on a flat, stable base is important. Anchoring the shed and placing it away from direct wind helps improve overall stability.

Bike Shed

Bike sheds are a practical way to store bicycles securely and protect them from the elements. Leaving bikes outside exposes them to rust and damage caused by rain and temperature changes. A lockable bike shed with strong doors and weatherproof construction offers reliable protection. When installed on level ground and anchored properly, it stays secure even in high winds. Some models also feature internal racks to keep bikes upright and organised.

Bin Storage Shed

Bin storage sheds help keep wheelie bins out of sight and protect them from wind or animals. They provide a cleaner, more organised look to gardens and driveways. Many are made from weather-resistant materials like wood or resin and include ventilation to manage smells. Models with lift-up lids and front access make bin use easier on collection days. A level surface with good drainage helps maintain the shed’s structure and cleanliness.

Shed Sizes

Finding the right shed size is often where most people trip up- it’s either too small to store everything or so big it dominates the whole garden. A well-chosen shed doesn’t just house your tools; it helps keep your space tidy, adds value, and keeps your life organised.

What shed sizes are most popular?

The UK has a few standout shed sizes that tend to suit most garden spaces and storage needs. Choosing the right one depends on how much kit you’ve got, how you plan to use the shed, and the space available in your garden. Here's a breakdown of the most common options people go for in the UK, along with what each size is best suited for.

6’x4’ Sheds

This compact option is ideal for small gardens or those just needing a basic storage unit. It’ll hold your essential gardening tools, a lawnmower, and maybe a bike or two. It’s perfect for people who want to keep things minimal but still tidy. A 6x4 won’t eat up your outdoor space, which is a blessing if you’ve only got a wee patio or courtyard to work with.

6’x8’ Sheds

A step up in size, this is where you can start to get more organised. It’s ideal for households with more tools, DIY gear, or for those who want a bit of workspace in addition to storage. It fits comfortably in most suburban gardens and allows shelving or a small potting bench without feeling cramped.

7’x5’ Sheds

This one’s a bit of a middle ground. It gives you more width than a 6x4, without being as long as a 6x8. It’s great for awkward garden shapes or when you need a bit of extra space but don’t want a full-size workshop. It’s often picked by people who want a multi-purpose shed: store your gear one side, and use the other for planting or hobbies.

10’x6’ Sheds

This is the point where your shed becomes more of a working space. It’s popular with those who do a lot of DIY, woodwork, or need to store bulky items like bikes, garden furniture, or even motorbikes. It still fits in most average gardens but gives you a serious upgrade in usability.

10’x8’ Sheds

If your garden allows, this is a brilliant size for those who want flexibility. You can store everything from bikes to BBQs and still have space to walk around or work comfortably inside. It’s a favourite for garden offices, creative studios, or full-on hobby rooms. And if you’re constantly running out of space indoors, this can take the pressure off.

12’x8’ Sheds

This is as big as most people go before venturing into summer house territory. It’s ideal if you need storage, workspace, and maybe even a place to relax. Think garden gym, bike garage, and workshop combined. It’s especially handy for households that have downsized or where indoor storage is limited.

What is the maximum size shed you can have without planning permission?

In most parts of the UK, you won’t need planning permission as long as your shed meets specific rules. It mustn’t be more than 2.5 metres high if it’s within 2 metres of a boundary. If it’s further away, you can go up to 4 metres for a dual-pitched roof. Also, the shed mustn’t cover more than half the garden area or be used as living space. Go over any of these and you’ll need to get permission from your local council. Always double-check with your local planning authority- especially if you’re in a conservation area or your home is listed.

Shed Roofs and Flooring

Different roof and flooring types have different properties which are worth considering whether you are buying a shed or building one from scratch. Here are common roof and flooring types you may want to use or may come across:

Shed Roofs

1. Apex Roof - An apex roof adds central headroom, making it easier to store tall tools and move around inside. Its dual slope helps rainwater drain quickly, reducing moisture build-up. This design suits those needing a spacious, weather-resistant shed. A reliable choice in any shed buying guide.
2. Pent Roof - The pent roof slopes in one direction, guiding rain away efficiently and preventing water pooling. Its shape fits neatly against fences or walls, saving space in smaller gardens. Recommended in a shed buying guide for compact outdoor layouts and easy placement.
3. Reverse Apex Roof - With the door on the longer side, a reverse apex shed offers wider access, ideal for storing bulky items. It improves movement inside and supports better organisation. This layout suits anyone using their shed regularly for tools or gardening tasks.

Shed Flooring

1. Wooden floor - Wooden floors provide a solid, sturdy base but are prone to rot if untreated. Pressure-treated timber and airflow underneath help prevent moisture damage. It's a common choice in a shed buying guide for general storage and light garden use.
2. Metal floor - Metal floors resist rot, pests, and moisture, making them ideal for damp British gardens. They support heavier loads but can feel cold underfoot. Adding a mat improves comfort. These floors are often recommended in a shed buying guide for durability.
3. Plastic floor - Plastic floors are rot-proof, easy to clean, and require no treatment. They suit gardens with high moisture and are simple to install. While lighter than wood or metal, they work well for everyday storage needs. A low-fuss option in most shed buying guides.

Shed Cladding

Shed cladding is the covering of the shed which protects it, but adds charm! There are various cladding options available and like roofing and flooring, it’s an aspect of your shed that’s worth considering.

Overlap Cladding

If you’re watching your budget but still want a decent shed for storing tools, bikes, or the kids’ garden toys, overlap cladding is a solid option. It’s made by layering horizontal timber boards over each other, hence the name ‘overlap’. The design keeps costs down, and while it may not offer the highest level of insulation, it does a good job of keeping the rain out if treated properly.

Shiplap Cladding

Shiplap is the next step up and a popular choice for British gardens prone to unpredictable weather. It features interlocking boards that create a tight seal, making it more effective at keeping out wind and rain than basic overlap. The flat, smooth finish also gives your shed a sleeker appearance, ideal if it’s going to be visible from the house or doubling up as a workspace. If you’re using the shed often or storing delicate items, this might be the right balance of price and performance. This shed buying guide highly recommends it for year-round use in British back gardens.

Tongue & Groove Cladding

If you’re after something that feels more like an outdoor room than a basic shed, tongue and groove cladding is worth the extra spend. It’s designed with interlocking boards that slot together tightly, offering superb strength and insulation. Not only is it more secure and weather-resistant, but it also gives your shed a polished, high-quality look that blends well with modern garden designs. This type of cladding is ideal if you plan to use the shed as a hobby space, garden office, or for storing valuable items like bikes, power tools, or electronics. A top pick in any shed buying guide, it’s built to last.

Shed Bases

Every shed needs a strong base - even small or lightweight sheds are at risk if placed directly on the grass or soil. Moisture can seep in, causing rot or rust. An uneven surface can lead to unstable walls and sagging floors. A good base prevents all of that by raising the shed off the ground, promoting airflow, and offering even support across the whole structure.

Pick a level, well-drained spot with easy access and avoid areas where water tends to gather. Once you know the location, here are the bases you can consider:

Concrete Base

A concrete base is ideal for anyone wanting a long-lasting and low-maintenance foundation. It is strong, secure, and able to handle both heavy loads and rough weather. The downside is the amount of work involved. You need to plan carefully, mix properly, and let it cure fully before placing the shed on top. Adding a damp-proof layer under the concrete also stops moisture from rising into the floor of the shed.

Wooden Base

A wooden base, sometimes called a timber frame or bearer system, is a quick and cost-effective choice. It lifts the shed above the ground and reduces direct contact with moisture. This kind of base suits smaller sheds and works best on firm and level ground. The wood needs to be pressure treated to resist rot, and you may need to check it from time to time for wear or movement, especially in wetter gardens.

Plastic Base

Plastic shed bases are lightweight, easy to install, and surprisingly strong. They are made of interlocking grids that allow water to drain away and air to circulate. They do not rot or rust and are a good option if you want a foundation that is quick to set up and easy to maintain. These bases also work well with a weed control membrane underneath, helping to keep the area clean and tidy. For many garden owners, plastic bases offer a fuss-free solution.

HOW TO BUILD A SHED

If you’re handy with tools, building your own shed might be something you’re eager to do. Here are some steps to follow to ensure you’re shed is secure and weatherproof.

1. Choose a flat, dry spot in your garden with enough room around the edges for access.
2. Lay a solid foundation using paving slabs, a concrete base, or treated timber blocks to keep the shed off the ground.
3. Build the floor frame using pressure treated timber and lay down the floorboards securely.
4. Measure, cut, and assemble the wall panels with screws or nails, then clad the outside with weather resistant boards.
5. Lift and attach the walls to the base and to each other, checking that everything is straight and level.
6. Construct the roof frame, then attach the roof panels or boards.
7. Cover the roof with felt or shingles to keep the rain out and ensure proper overlap and fixing to prevent leaks.
8. Fit the door with strong hinges and a lock. Add windows if required, using acrylic or toughened glass.
9. Apply a wood preservative or outdoor paint to protect against moisture, insects, and UV damage.
10. Do a full inspection, sealing any gaps and tightening any loose fittings for a weatherproof finish.

Keep in mind…

Building your own shed might seem like a money-saver. But once you add up the cost of timber, roofing, fasteners, and finishes, plus the time it takes to do it all right, it might not be as cheap as you’d think. DIY sheds can be rewarding and customisable, but mistakes during the build can cost more to fix than buying one upfront. Make sure if you choose to build a shed that you have the skills and materials required.

HOW TO MAINTAIN A SHED

It's important to take care of your shed to keep it in the best condition possible. This will not only extend it's lifespan, saving you money, but also protect your belongings. Here are some tips to help you maintain your garden shed:

1. British weather can be harsh on sheds, especially with constant rain and damp air. Apply a quality sealant around edges and joints, and use waterproofing paint or membrane on the roof and exterior panels. This helps prevent moisture from seeping in and damaging the contents.
2. Rot and rust are common shed killers if left unchecked. Treat wooden sheds annually with a wood preservative, and use anti-rust coatings on metal sheds. Choose materials that are already pressure-treated or galvanised for better resistance.
3. Leaks, pests, and structural issues can worsen quickly if ignored. Inspect your shed monthly for signs of water stains, droppings, or sagging panels. Early detection makes repairs quicker and cheaper in the long run.
4. Keeping your shed clean improves its lifespan and helps spot issues early. Sweep out debris, wipe surfaces, and remove cobwebs regularly. Repaint or restain wooden sheds every few years to maintain protection and appearance.

FAQs

What is the life expectancy of a shed?

The life expectancy of a shed depends on factors such as the material used, the level of maintenance, and the environment it is placed in. A well-built timber shed that is properly treated and maintained can last between 15 and 25 years. Metal and plastic sheds tend to have a longer lifespan and may require less upkeep.

Is it worth buying a second hand shed?

Purchasing a second hand shed can offer short term savings, but there are important considerations. Structural integrity, weatherproofing, and the condition of the timber or panels should be assessed carefully. Transport and assembly may also incur additional costs. In some cases, investing in a new shed with a warranty and modern materials provides better value over time.

Does a shed add value to your home UK?

A high quality and well maintained shed can contribute to a property's overall appeal and functionality. While it may not significantly increase the market value, it can enhance the attractiveness of outdoor space for potential buyers. Garden buildings used as home offices, workshops, or hobby rooms are particularly appealing in the current property market.

Do I need a permit to run electricity to my shed in the UK?

Running electricity to a shed in the UK is considered notifiable work under Part P of the Building Regulations. This means the installation must comply with safety standards and be carried out by a qualified electrician who can certify the work. In some cases, building control approval may also be necessary.

Is a double door shed better than a single door?

Double door sheds offer easier access and greater flexibility when storing larger items such as lawnmowers, bikes, or garden furniture. They also allow for better ventilation and light. However, single door sheds may be more suitable for compact spaces or when a streamlined design is preferred. The choice depends on storage needs and garden layout.

What is the best thickness for a garden shed?

The ideal wall thickness for a garden shed depends on its intended use. For general storage, cladding of around 12mm to 16mm is commonly used. Heavier duty sheds or those used year round may benefit from thicker walls of 19mm or more. Thicker panels provide better insulation, durability, and resistance to weather conditions.
