The inner walls of our garden rooms are made using a fire-resistant fibreboard for increased protection. This is a hard-wearing material made from recycled paper fibres and Gypsum (Hydrous Calcium Sulphate). The fibreboard is supplied unpainted so you can design and decorate the interior of your garden room to your style. This material is a good surface for paint and is easy to wallpaper.

On all of the garden building test and demonstration units that we have built, we have always painted directly onto our fermacell gypsum boards, as do most of our customers, without issue. However, as we do not know your preferred finish or paint type if you have specific requirements, we recommend that you speak to an interior decorator, as you may prefer to apply a primer or similar fine surface treatment before painting

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!

Purlins are the large timbers used for structural support in buildings. We use very thick, heavy duty roof purlins to support your garden building.  At 140mm x 45mm they are amongst the thickest purlins available on the UK market. Competitors will often use thinner purlins to keep their costs down which means their roofs will not be as strong as ours. Using thinner purlins risks the roof collapsing or sagging during extreme weather – and that’s the last thing anyone wants!

Get your garden office up and running quickly and easily thanks to the full panels provided. No need to waste time building up walls or fixing doors together.

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.

Your security is of the utmost importance to us.  You have invested your precious time, thought, and money into creating your perfect garden building, therefore we want to ensure your valuables are as safe as they would be inside your own home.

Our doors feature an industry-leading domestic standard 6-point locking system consisting of espagnolettes, which slide in opposite directions as well as a 6-pin Euro cylinder, which has been tested to BSEN 1303:2005 classification, plus 2 shootbolts. Making it difficult for intruders to break in and steal your precious belongings.

Most companies will use a cheap and simple 4-point locking system. For us it’s a no-brainer – why would you compromise your security when we offer the best on the market!

Our windows use espagnolettes, which pull the window tightly into the draft seals attached to the frame. We also supply a solid handle and key that allows you to lock the window whilst you’re away. Most competitors only supply a multi-purpose stay arm opener for both locking and keeping the window open.

When constructing your log cabin, you do not need to worry about putting our timber windows together, as they come preassembled. So you simply need to slot them in, and fit the finishing touches. After all, we take pride in our DIY-friendly designed products. Many competitor products require you to painstakingly construct the windows and other hardware, such as window trims, and install the glass.

Did you know? You can also add a little character to your timber windows with some stylish Georgian bars, which we supply as standard. However, this is entirely optional and up to you. Not all products offer Georgian bars, so be sure to check the product specification.

Please note: If you upgrade to uPVC Windows and Doors, the glass is not pre-fitted.

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.

Ventilation is essential for the longevity of the Garden Building. This is to ensure airflow and minimise moisture at all times. We have provided ample vents to ensure that condensation is never a problem. Some competitors charge you extra for these or do not even offer them.

Lightweight and flexible. Multifoil is ideal for use in Garden rooms like the Dominator. It is preinstalled in the roof and wall panels and is just unrolled across the ground bearers for floor insulation. As it comes on a roll the floor installation is quick and very easily installed.

If you had any doubts as to the quality of the insulation, don’t!  Firstly, it’s made from 40% recycled material, so it’s great for the environment, but not only that it’s of a high enough standard that it can be used in homes as part of roof, walls and floor insulation.

When comparing competitor products, be sure to check what insulation is used. Some competitors may use cheap materials such as bubble wrap which is nowhere near as effective!

A low U-Value means that your walls, roof and floor radiate less heat, in reality, you keep cool in the summer and warm in the winter whilst having lower energy costs. The Dominator has low U-Value walls, roof and floor thus keeping your running costs down. The walls have a U-Value of 0.63, roof U-Value is 0.49 and the floor U-Value is 0.64.

The lower the U-Value the better! Be weary of any competitor products on the market that don’t advertise U-Values.

Wish to customise your Garden room? As the wall panels supplied are of the same size, this means that a wall panel can be replaced by a window panel (for instance) and the wall panel used elsewhere, the doorway (2 panels) can be changed with any mix of 2 panels.

You could put the door on a side aspect and have a wall of windows to the front aspect if that is how you want your Dominator to look.

Customise the Dominator to a configuration that works for you!

The bearers of your garden building are pressure treated to help protect your garden building from the ground up. We provide a 10 year guarantee against rot and insect infestation for all pressure treated timbers.

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

Both our doors and windows are fitted with internal beading used to secure the glazing in place. This beading style is typically found in uPVC windows and is a proven method of security. However, there are still some companies that externally bead their windows. Allowing intruders to remove the glazing from the outside of your garden house and gain access.

All of our garden buildings have pressure-treated floor bearers as standard. This treatment prevents the timber bearers from rotting for up to 10 years and causing your garden building to sink. Pressure treatment forces the wood preservative into the timber rather than simply dip treating (essentially just covering the exterior) like many companies still do. Who wants to have to annually deconstruct and re-treat the bearers each year!

Due to this costly but effective process, we can offer our customers a genuine 10-year guarantee against rot and insect infestation on the bearers.  We do however recommend applying a good quality water repellent to the timber to prolong the longevity of the timber. Shockingly many of our competitors still offer untreated bearers to keep their costs down, so beware!

All our Pressure Treated timber is for Use Class 3

Unlike some, we only use full-length cuts of shiplap cladding on our garden offices, which comes in a substantial thickness of 15mm. The advantages of using shiplap cladding is it is robust and sturdy.

Our cladding interlocks, creating a strong watertight bond that allows rain to run off the office quicker, it also creates an attractive, professional appearance, that’s certain to wow potential clients if you’re running your business from home.
