Which Timber Shed Should I Buy and Why?

Part of their success is likely attributable to the fact that, being a natural material, timber blends in well with the environment and, thanks to modern technology, can be guaranteed of a long lifespan.


The majority of timber sheds will be manufactured from northern European mixed softwoods, and all Power Aggregates sheds will be made from sustainable and well-managed forests, as indicated by the FSC (Forest Stewardship Council) logo.

Chipboard and OSB can be utilized for flooring and roofs. OSB, or Oriented Strand Board, is constructed comprised of compressed wood flakes and glue in the shape of durable sheets. It’s a great material for various purposes because it’s strong, rigid, and waterproof.

Roof Designs

The apex roof is shaped like a triangle. As a result, there is plenty of headroom in the center of the shed, and glazing can be installed on either side. To take advantage of the height, sheds with apex roofs usually have their door/s on the end, but if the shed has a reverse apex roof, the entry will be on the side.

Pent roofs have only one sloping surface, with the highest point over the front and rain running off the back. As a result, the front of the shed has the most headroom and glazing, and the back has the least. The entrance could be in the front or side of the building.


A shed’s cladding, or walls, are available in four different types.

The most prevalent is overlap. The rough sawn planks are nailed to a frame and overlap slightly, creating a ‘rustic’ aesthetic akin to feather edged fencing but horizontal. This is the most economical choice. Some distortion may occur over a long period of time.

Shiplap is similar to tongue and groove, but it is curved to allow rain to flow off more effectively, reducing the risk of water seeping into the joints and causing expansion, distortion, or rot. This type of cladding is more expensive, but it provides the most rigidity and durability.

Tongue and Groove cladding is made up of interlocking boards with one side’s ‘tongue’ fitting snugly into the next board’s ‘groove.’ This is a more solid design that looks very nice, provides the finest wind and rain protection, and has a far lower likelihood of distorting.

The popularity of loglap has grown owing to its look more than any added strength. Smoothly planed rounded timbers join with tongue and groove to create this covering. Rain quickly disperses, and the shed resembles a log cabin rather than a rustic shed.


Timber will either be dipped or pressure-treated to ensure its lifespan.

Dip treatment is a way of adding anti-fungal preservative to timber by dipping it into a tank of preservative before putting the shed together. Dip treatment is a less expensive and faster technique than pressure treatment, hence dip treated sheds are less expensive. However, it only provides short-term protection, and you must re-treat the shed with a preservative once a year to avoid drying out and warping, as well as to comply with the guarantee’s terms and conditions.

Vacuum Pressure Impregnation or Tanalising are other terms for pressure treatment. The wood is first dehumidified before being placed in a pressure treatment tank where air is extracted using a vacuum. The tank is then filled with preservation liquid, which is drawn deep into the grain by the wood.

When new, pressure-treated materials have a green tint to them, but this fades to a honey brown color with time. Green dots on the wood indicate that the salt has been driven out of the wood, indicating that it has been fully pressure treated. These patches are not dangerous and will not shorten the life of your shed; they will wear out naturally or may be brushed off.

All of our wood sheds come with a lengthy rot guarantee. There should be a ten-year anti-rot guarantee if the wood has been dip treated, and a fifteen-year guarantee if the wood has been pressure treated. Their lifespan can be extended significantly with adequate care and attention.

Roof Security

Traditional roofing felt will be used on the majority of timber sheds to guarantee that the construction is waterproof. This roofing material comes on a roll and is nailed to the roof. It will need to be replaced on a regular basis, depending on the quality.

Onduline is a durable, lightweight corrugated sheet comprised of cellulose fibres that have been soaked in bitumen as an alternative. This is a long-lasting, cut-to-size material that provides both waterproofing and insulation.


Glazing is vital since it permits light into a shed so you can see what you’re doing, unless security is a concern. Glass has always been the preferred material, however many sheds now employ a synthetic substitute.

Glass is easily broken, whether when it is being installed or later by a stone or a football. Toughened glass will not shatter into dangerous fragments, but it will need to be replaced anyway, if only to keep your shed looking tidy.

Acrylic, Styrene, and Polycarbonate are superior in terms of strength and shatter resistance, as well as the capacity to withstand strong impacts. Furthermore, both are lightweight and easy to handle, have good light transmission, and are more insulating than glass.


Although painting is not required, wooden sheds can be painted at any time after delivery, however some manufacturers advise waiting at least six months for any pressure treatment to settle entirely.

If you do decide to paint your shed, we recommend choosing a quality branded outdoor wood paint like Cuprinol, Ronseal, or Sadolin. When it comes to putting a fresh coat of paint, we recommend following the manufacturer’s instructions (normally once per year thereafter).

Cracks and Splits

Because timber is a natural product, it may develop splits and cracks as a result of daily and seasonal temperature and humidity fluctuations, which cause the wood to expand and contract.

Splits and cracks are common in natural wood, so they’re nothing to be concerned about. It will not damage the strength or structural integrity of your shed in 99 percent of cases.


There are so many different sizes and kinds of wooden sheds that they may be used for a wide range of purposes, not simply as storage areas for anything that would otherwise clutter the house.

Most sheds will have adequate glazing, either acrylic or glass, to provide plenty of light into the interior for a variety of activities. As the size of the structure grows, you’ll have more alternatives for DIY projects, gardening, and hobbies, until you reach big workshop-style structures.

If you have valuable equipment inside, however, you may want to consider a’security shed,’ which has extremely little or no windows. These sheds will also be equipped with pad bolts and other features that reduce the likelihood of a break-in.


It’s critical to start with a sturdy, level foundation. Concrete, pavement slabs put on sharp sand and hardcore, and timber foundations are all options. Bearers attached under the shed floor should lift the construction 1.5 inches from the prepared base, allowing air to flow freely. Alternatively, some sheds come with a ready-made base that is secured to the ground by spikes.

Manufacturers of Wooden shed

Forest Garden has been creating and manufacturing its comprehensive Forest sheds collection for the past 50 years to suit most locales, uses, and budgets. The majority of the timber they use comes from Dublin, which they source and treat in their own sawmills.

From 4ft x 3ft to 12ft 8ft, their overlap dip treated and pressure treated sheds and workshops are available in a variety of sizes and styles. They have apex or pent roofs, hidden hinges, hasp and staple latches for security, durable double Z braced doors, and polycarbonate windows where applicable. Dip treated sheds have OSB flooring, whereas pressure treated sheds have timber floors, as do the smaller Shiplap Dip, Treated sheds and workshops that have the same qualities.

There’s also a line of pressure-treated Premium tongue and groove sheds with added features like opening acrylic glass windows with quality locks, highly durable timber boarded roofs with hardwearing black mineral felt, T&G flooring, and a rim lock on the door. Forest also includes a number of specialty stores that provide garden equipment, tools, and bicycles to round out their offering.

Rowlinson Sheds, founded in 1926, is another well-known timber goods company. Their shiplap dip treated apex roofed sheds start with two 4ft x 6ft sheds, both with boarded floors, but one is glazed and the other is security oriented with one very small high window, a padlock protector, and lockable hinges. There are a variety of sizes available in the same styles, all of which have the same appealing honey brown color.

Their Premier sheds have double doors for easier access, a tongue and groove floor, sturdy construction, and a pad bolt. Some even have an opening window for greater ventilation, making the interior a more appealing area. If you prefer a more traditional look, their two Heritage sheds contain contemporary components but have vertical cladding and a grey paint finish.

The four Rowlinson workshops are especially stunning, with plenty of light coming in from the front and one side, double doors to handle huge equipment, and high eaves. Two Potting Stores, one of which is curved to fit into a corner, are very useful for gardeners because they are extraordinarily well glazed, ventilated, and already equipped with benches. There is also an unglazed room at the back for storing tools and other gardening equipment. Finally, Rowlinson’s portfolio is rounded out by a number of small shops selling outdoor tools, equipment, and bicycles.

Shedlands is a family-owned business that has grown significantly over the last two decades and now offers a wide range of cheap sheds in a variety of sizes and styles. These sheds have great specifications and various uses, thanks to the use of dip-treated wood, tongue-and-groove cladding, and classic horticultural glass.

Starting with the 6ft x 4ft Apex or Pent, there are a variety of sizes available, ranging from 6ft x 4ft to 12ft x 8ft. Coach bolt assembly, cross-braced smoothly planed structure, high-quality roofing felt, and a rim lock and doorknob are included in Heavy Duty sheds. No OSB is used, and Georgian style windows enhance the aesthetic of the sheds.

Security Sheds from Shedlands are equally solidly built, but the windows are internally glazed, small and high to keep the contents hidden, and there is also a no window option. There’s a Corner Shed that fits neatly into a garden corner, and Potting Sheds with ample amounts of glazing for the eager gardener, as well as a handy stable door, in the Dutch Barn style.
