Head Judge: Andrew Wilcox
Channel 4’s Head Judge & Founder of Shed of the Year Andrew Wilcox has worked to help design an impartial judging system for WhatShed. The judging system uses many different parameters to help give a large degree of impartiality to the way we select products for each of the league tables we do. You can read more about the system here.
If you have a big garden, or need a large auxiliary space to use as a workshop for business or a hobby, then a large shed can be a perfect addition to your property. A large shed can be whatever you want it to be. It can be traditional storage for garden tools, bicycles, and outdoor equipment, or a space to work on DIY projects. It can even serve as an extension to your home – although we do advise looking at our log cabin or summerhouse recommendations for a more comfortable outdoor living space than those structures considered garden sheds.
Whatever you want to use it for, you’ll find that there’s a huge number of large garden sheds available. Loads of manufacturers offer many different options, mainly in wooden sheds and then metal sheds. To help save you time we’ve created this handy WhatShed league table to show you the best of what’s out there.

Tiger Elite Pressure Treated Apex Shed
Here at WhatShed, we’re constantly amazed at the attention to detail that goes into all of TigerSheds’s products. The Tiger Elite Pressure Treated Apex Shed is no exception.
Available in a number of sizes, the largest being 16’ by 8’, and featuring vast double doors (not pictured) that are fully braced with both “Z” style and square framing, this large range of garden sheds has clearly been designed with durability and security in mind. Throughout the Elite, TigerSheds shows that it is willing to go the extra mile to create a shed that’s truly built to last. Touches like the 58mm x 44mm framing, and 16mm tongue and groove boarded floor, roof, and walls, and the use of tantalised, slow grown timber throughout puts this garden building in a league of its own when it comes to the longevity of wooden sheds.
Despite its rugged functionality, the Tiger Elite is still a looker. We loved touches like the antique hinges and door handles, as well as the muted wood tones of the pressure-treated timber. TigerShed calls this “the ultimate garden shed”. Honestly, we can see why.
Why WhatShed loves the Tiger Elite
- Pressure treated throughout with a 15-year warranty.
- Extra thick, heavy duty framing and cladding.
- Tongue and groove construction throughout.
- Rugged but with a lot of style!
- Buy direct from the manufacturer for a better customer service experience.
8' x 12' Palram Grey Skylight Plastic Shed (2.37m x 3.79m)
Plastic garden sheds are typically nowhere near as popular as their wooden counterparts but modern products, like the Palram Grey Skylight, look set to change that. People often think of a plastic shed as being less secure than a wooden or metal one. However, with modern polycarbonate walls and roof, supported by a galvanised aluminium framework, the Skylight offers substantial protection from the weather, as well as unwanted intruders. Front and rear venting allows for airflow inside without creating a potential access point that would require securing.
Palram clearly understands that security is often a chief concern of shed owners and, as such, has constructed the Skylight without windows. However, rather than let that functional design choice dictate the utility of the interior space, the manufacturer has included unique translucent polycarbonate glazing in place of opaque roofing. It’s virtually unbreakable and lets in light whilst providing UV protection.
In terms of looks, the Skylight is basic but does feature a tasteful apex roof. This 8′ x 12′ shed is available in dark grey and has a distinctly utilitarian style.
Perhaps the best thing about plastic garden sheds like the Palram Skylight is that they require no treatment whatsoever. Once you’ve built it, you can get on with enjoying it, rather than worry about giving it a new lick of paint every year as you would with large garden sheds made from wood.
Why WhatShed loves the Palram Grey Skylight
- Ultra-durable, almost indestructible design.
- Functional interior space thanks to polycarbonate skylight design.
- No need for annual treatment.
10' x 12' Lotus Heritage Green Apex Metal Shed (3.07m x 3.71m)
If you’re really serious about shed security, Lotus by Globel offers a range of exceptionally high-quality products for incredibly competitive prices.
In terms of the large sheds currently on offer from the company, we could barely fault the Heritage. This 10’ by 12’ metal shed is constructed entirely from hot dipped, galvanised steel. The structure’s 3mm thick roofing and walls really make it stand out in its class. Typically, those metal sheds with 1.5mm or 2mm thick steel or aluminium walls will bend slightly under pressure. That’s not the case with the Heritage. This thing feels rock solid.
Like most other metal sheds, the Heritage is optimised for security. As such, it does not have windows. However, the manufacturer does offer a window kit for an additional fee.
Despite the heavy-duty design, careful planning on Lotus’s part has ensured that the Heritage is easy to assemble. As part of these minimalist assembly requirements, it features special profiled sheet walls that bolt together to create a robust and lasting structure at a fraction of the time it would take to construct a wooden shed.
Although the Heritage has been built to be as secure as possible, it isn’t just some hideous steel box. The classic green paint finish on the product means it will tactfully blend into most gardens.
The Lotus Heritage is available in a range of sizes from 6’ by 3’ to 10’ by 12’ for customers to choose from. For the purposes of this league table, we considered the latter.
Why WhatShed loves the Lotus Heritage
- Outstanding build quality. The 3mm sheet steel makes for an incredibly secure structure.
- Tasteful but practical design.
- Easy to assemble.
20' x 10' Shed-Plus Champion Heavy Duty Workshop / Log Store - Double Door (6.09m x 3.05m)
Possibly the most visually impressive of the large sheds for sale in the UK is the Heavy Duty Workshop with Log Store by Shed-Plus Champion. This feat of timber engineering measures approximately 20′ by 10′ and has a reverse apex roof. It really is something special but, as you might expect, it has a price tag to match.
The most dramatic thing about this product is certainly its vast log store at the side of the building. This is ideal for storing bikes, garden tools or, of course, logs for a home wood burner.
The entire structure is crafted from Nordic White Spruce, a slow growing species known for its suitability as a building material. The timber is pressure treated, which significantly improves its ability to withstand changing weather conditions. The manufacturer is so confident in this that it guarantees the product for 15 years without any need for subsequent treatment.
At 44mm square, the shed’s framework is suitably robust, inspiring yet further confidence in the product’s longevity and ability to withstand all that nature can throw at it. Similarly, the two large double doors are “Z” braced twice and framed for extra rigidity.
As you’d expect from such a high quality garden building, this Shed-Plus Champion product doesn’t come cheap. However, it is easily one of the most impressive of the very large sheds available today. If your space and budget will accommodate, it will no doubt continue to bring joy for many years to come.
The manufacturer also provides a lot of options to add upgrades to the standard model. The cedar slatted roof version of the product is even more impressive visually than the standard edition.
Why WhatShed loves this shed
- Vast garden shed with many bespoke finishing touches.
- Lots of options to add upgrades.
- Sturdy construction thanks to quality building materials.
TigerSheds XL Heavyweight Workshop
For its sheer build quality, the TigerSheds Heavyweight Workshop is one of WhatShed’s favourite large sheds. It’s available in a range of sizes from 12’ by 6’ to 20’ by 10.
TigerSheds uses slow grown timber throughout its builds. The floors, walls, and ceiling of the XL Heavyweight are all cladded with dip treated 12mm tongue and groove boards. The building’s framework is 28x44mm, making it highly secure and stable. For additional support, the spacious apex roof has a sturdy truss rod running its length.
In terms of style, the XL Heavyweight is somewhat plain but highly functional. It features extra tall eaves and doors, and on the largest model, a total of ten 2mm styrene windows. This allows for ample access and lets lots of light into the space. The only other stylistic touches are the black antique style hinges, but TigerSheds does offer a range of accessories, such as shelving and planters, at an additional cost.
Although certainly not the cheapest large shed on our list, this model is exceptional value for money, particularly given its fantastic build quality. Even on more expensive sheds, it’s common to see inferior single sheet roofing or flooring. TigerSheds’s 12mm tongue and groove alternative offers a clear improvement in terms of its support underfoot and its longevity.
What WhatShed loves about the XL Heavyweight
- Outstanding build quality. Substantial materials favoured throughout.
- Largest model is a very large shed.
- Highly functional design.
Walton’s Dutch Barn Tongue and Groove Apex Garden Shed
Walton’s Dutch Barn is a high quality, attractive large garden shed that is built to last. Its most noticeable feature, of course, is its large, four-sided roof construction. This visually appealing design isn’t just for style. The spacious roof area is ideal for storage, significantly increasing the overall utility of the shed’s interior.
In terms of its construction, this 10’ by 8’ shed features many touches that ensure a robust finished structure. The walls, floor and roof are all constructed using interlocking, 12mm tongue and groove boarding. Supporting the structure is a sturdy 2” by 1” framework and the roof is finished with durable mineral felt.
The same quality construction techniques are followed in the product’s extravagant roof design, with extra chunky struts supporting the unconventional structure. All timber used throughout the build comes dip treated and, unlike pressure treated models, will require annual reapplication of an appropriate preservative product.
Like many other large sheds, Walton’s Dutch Barn has spacious double doors. These are double “Z” braced, making them especially strong. The two reasonably sized windows are glazed using shatterproof styrene.
What WhatShed loves about the Dutch Barn
- Solid construction for a good price.
- Highly functional space ideal for multiple uses.
TigerSheds Heavyweight Workshop Shed with Log Board Cladding
Undoubtedly one of the best things about TigerSheds’s service is the fact that the firm operates its own sawmill in Yorkshire. This gives the firm the freedom to make some really special garden buildings. With its log lap cladding, this edition of the Tiger Heavyweight is certainly amongst them.
As you’d expect from a TigerSheds product, the build quality throughout the Heavyweight is exceptional. The tongue and groove cladding used for the walls is 15mm thick, much thicker than even TigerSheds’s usual 12mm, which is reserved for the roof and floor of the model in question. Such construction methods are far superior to the overlap cladding seen on cheaper, lower quality large shed designs.
This edition of the Heavyweight comes in four sizes, ranging from 10’ by 8’ to 16’ by 8’. It features extra tall double doors, which make it easy to access. Meanwhile, the largest version comes with a total of eight 2mm styrene windows. Since TigerSheds builds sheds to order, customers can choose the location of these windows, along with other design choices.
What WhatShed loves about the Heavyweight Shed
- Log lap finish provides added style and additional weather protection and insulation.
- Great overall build quality.
- Dealing direct with the manufacturer usually results in a better customer service experience.
- Lots of options for the customer to personalise the shed and to add the extras they choose.
12' x 8' Forest Tongue & Groove Apex Pressure Treated Wooden Double Door Shed (3.91m x 2.62m)
This spacious garden building from Forest is another classic apex shed that features superb construction methods throughout. Like many of our other selections on this large sheds league table, it’s walls are clad using 12mm tongue and groove boards, as are its roof and floor. Forest opt for a thicker-than-average framing timber too. Holding the cladding in place is a 45x28mm pressure treated framework.
Being pressure treated, this large wooden garden shed will be weather resistant from first assembly. Unlike dip treated products, there is no need to annually apply a suitable wood preservative. It comes with a 15-year anti-rot guarantee as well.
We were particularly impressed by the product’s large double doors. The over-sized double “Z” bracing is immensely tough and will no doubt bring a lot of peace of mind to the building’s eventual owners for many years to come.
Letting light into this 12’ by 8’ Forest shed are are six fully-opening acrylic windows. These run along the length of the building down one side. Finishing the roof are tasteful barge boards bordering heavy duty mineral felt.
Why WhatShed loves this shed
- Robust design.
- Pressure treated reducing maintenance time.
- Tasteful special finishing touches make an attractive yet functional shed.
8' x 6' Forest Kielder Overlap Dip Treated Pent Wooden Shed
This shed by Adley has a quaint pent roof design that would be ideal for those wanting a large shed but without it imposing on the rest of the garden too much. The building has two large double doors on its front, along with two reasonably sized fixed styrene windows. The doors themselves are suitably sturdy too thanks to double “Z” shaped bracing on each.
The shed walls are built using 12mm tongue and groove shiplap cladding. Vastly superior to overlap cladding, the snug fitting boards form a much more effective barrier against the elements. The shed’s roof and floor construction uses the same thickness boarding.
All the timber used throughout this Adley product has been pressure treated. By submerging timber in wood preservative in a pressurised environment, treatment is forced deep within its grain. This gives it superior weather resistance to dip treated equivalent products, even without subsequent treatments.
One of the few faults with this pressure treated model is its framing. At 28mm square it’s by no means the thickest on the market. It’s not dangerously thin but there are certainly stronger sheds out there.
Why WhatShed loves this shed
- Quaint look for a larger shed.
- Pressure treated for minimal upkeep.
- Solid tongue and groove construction for superb weather resistance.
Walton’s Shiplap Pressure Treated Reverse Apex Shed
Whilst not the largest shed on our list or the most visually distinctive, there’s still a lot to like about this 10’ by 8’ pressure treated, reverse apex model from Walton’s. As a pressure treated product, the timber used throughout its construction has had preservative forced deep within its grain to provide an exceptional level of weather resistance. The process also means that owners will never need to treat the timber to benefit from a generous 15-year guarantee. It arrives in a tasteful natural timber colour and should remain that way for many years to come.
The building’s walls are constructed using 12mm tongue and groove shiplap cladding. This provides an exceptionally snug join and is effective at preventing draughts in the interior space that you might find with products with overlap cladding. Its single but large window is glazed using 2mm styrene, which is pretty much the industry standard for this material.
Although a good product for the price, we were a little put off by a few aspects of its build quality. The framing, despite being pressure treated, is only 1” square, meaning it’s half as thick as some competitors’ products. Similarly, the floor and roofing are taken care of using 9mm thick sheet boarding where many competitors would favour tongue and groove boarding. Finally, the single door is only braced horizontally. Whilst such design choices do undoubtedly make this Walton’s product inferior to others on our list, it’s priced very competitively in the pressure treated large shed market.
What WhatShed loves about this shed
- Good value for a pressure treated product.
- No need for subsequent treatments.
