All our garden buildings have been designed on the basis that any competent DIY customer should have no problem installing a product themselves in a short amount of time. You do not have to be an expert at DIY to build a Dunster House garden building, as we do provide you with comprehensive pictorial instructions. We totally understand that DIY is not for everyone therefore, you may want to consider getting in touch with a local carpenter or handyman to install it for you. But before you do, check out our construction video and decide for yourself!

Many people like to show off their pergola by growing plants that will climb up the structure to highlight this wonderful focal point in their gardens. Some excellent plants to choose from for climbing up your pergola include wisteria, roses, vines or clematis. Thanks to the effectiveness of our pressure treatment used to make our timber last, you don’t need to worry about allowing such plants to climb up the pergola and make it look beautiful.

We use strong 70mm x 70mm posts, made from pressure treated slow-grown spruce in the construction of our stunning Utopia pergola range. Rest assured once the Utopia is secured in place it won’t be going anywhere!

The thickness of the roof beams on our Pergolas show how the quality of our products is superior in that we are never sparing with the amount of timber we are willing to use. We do not compromise on quality when it comes to ensuring that our timber products will last and will stand the test of time and weather wear. Added to the increased durability of the thick beams, they also look impressive and will make your pergola stand out in your garden, adding to the magnificence of your new garden centrepiece.

All of our timber Pergolas, Gazebos, Carports and Porches are fully pressure treated as standard. We take the pre-cut lengths of timber and place them in a large pressure treatment tank, where the timbers are impregnated with a non-toxic preservative. We add a colourant during this process, giving the timber a rich brown colour. By pressure treating the timber, we can offer a genuine 10-year guarantee against rot and insect infestation. We only suggest that you apply a good quality water repellent to prolong the longevity of the timber.

All our Pressure Treated timber is for Use Class 3. It involves the application of preservatives using a vacuum.

The below image is a figurative example of how pressure treatment penetrates wood more effectively than the dip treatment technique which does not penetrate wood in the same way, often only providing a surface coat of treatment and stain. This method therefore offers less resistance to rot and decay.

Unlike some competitors, we pressure treat our timbers and what is more, we treat only after cutting to ensure no timber ends are left exposed!

A lot of dip-treated sheds require a preservative to be added upon installation or within one year of purchasing their sheds. Ours do not require this, saving you time and money!

Customise your garden structure by adding timber panels. The addition of wall panels will provide a useful and attractive way to hide certain areas of your garden. You can combine the half height panels with full height panels on the other sides of your structure, or even choose half glazed panels.

All of the timber in this garden building has been responsibly sourced and pressure-treated to ensure it lasts. Pressure treatment forces the wood preservative into the timber rather than simply dip treating (essentially just covering the exterior) like many companies still do.

Unlike some competition, we can offer a genuine 10-year guarantee against wood-eating fungal and insect infestation on pressure-treated timber.

All our Pressure Treated timber is for Use Class 3.

Unlike our competitors, we only use high-quality spruce timber on our wooden products rather than cheap pine or mixed timber. Why do we use slow grown spruce rather than the much cheaper knotty pine alternatives?

Spruce is considered more stable as it expands and contracts less than pine. This stability means that the spruce timbers in our garden buildings minimise splits from appearing as the timber changes along with the weather. We responsibly source all our timber, where it grows slowly in the cold northern regions. We all know the old adage of counting the rings to see how old a tree is, well our timber grows slower and takes longer to get to size meaning it has more rings in it. This means it has a tighter grain, and each ring helps prevent cracks and shakes from appearing in the densely packed timber.

Our wooden garden buildings and climbing frames really are built to last therefore we use only the highest quality, slow-grown spruce. Spruce is much more resilient to warps and splits compared to its cheaper alternative pine. Being a whitewood, it doesn’t discolour anywhere near as much as pine so it is also much more aesthetically pleasing for a garden structure. Considered more stable, less knotty and resinous than pine, spruce will also produce a lot less sap. It is also less dense meaning it is not as susceptible to mould and rot.

This garden building is under 2.5m high. Why does this matter? Under permitted development rights, buildings under 2.5m high can be placed as close as you want to a boundary (eg. a fence line) without planning permission. Garden buildings that are over 2.5m high need to be placed over 2m away from any boundary (eg. a fence line), which could lead to a lot of wasted space. If you want to find out more about permitted development rights see our planning guide.

Selecting the HighRise Extension option for your log cabin will result in the height exceeding 2.5m high. This will mean that your building may need planning permission – contact your local council for more information or find out more by visiting: Planning permission: When you need it – GOV.UK.

There is nothing more annoying than being in the middle of building something and finding that you don’t have the right fixings to continue. We include all of the screws, nails and fixings that you will need to put your garden building together – not many of our competitors are that thoughtful. This eliminates the need to worry about the type of screws or the length of nails you might need to get started – it’ll all be with your delivery.

Due to the unique design of a Dunster House product, in the vast majority of cases our garden buildings can be installed without the need for planning permission.

However, there are a few other factors to consider:

As all properties are different in size, shape and style we can only advise based on how we have designed our products, not on your property.

When to consider planning permission:

If the garden building exceeds over 2.5m tall – the majority of Dunster House buildings do not exceed this. If you intend on putting an outbuilding in front of the main elevation of your property (as it was originally built or as it was on 1st July 1948) will require Planning Permission. If you live in a listed or graded building If you live in a designated area such as areas of outstanding natural beauty, national parks, world heritage sites and conservation areas. If there is a possibility that over 50% of your garden would be taken up by outbuildings.
