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!

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

Our garden rooms are supplied with domestic standard uPVC windows and door frames available in White as standard or Anthracite Grey Wood Effect. So you can either tie in with your home frame colours or customise your office or garden room!

Not all double glazing is the same, and what truly makes our double glazing stand out among the rest is the sealed unit. We supply a 28mm, double glazed sealed unit. These units comprise of 2 panes of 4mm toughened glass on either side of a 20mm aluminium spacer bar, designed to absorb any moisture within the sealed unit, which could lead to condensation inside the glazing. These sealed units comply to BS EN 1279 standards. This EN standard covers the requirements for insulating glass units, including thermal and sound insulation. The sealed units are independently tested to show that they will not suffer from any form of condensation within the unit.

We’ve been manufacturing uPVC windows and doors for over 30 years – so we really know our stuff!

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.

The Spaceship has launched, compact yet surprisingly spacious (room for a worktop that holds 2 screens) it will appeal to those that have limited space or want a smaller isolated area for peace and quiet.

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.

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!

Security is something that shouldn’t be overlooked when designing a garden office, especially when storing valuable equipment. Which is why we have included our industry leading 10-point locking system on the wide opening uPVC doors as well as multipoint locking windows which feature secure key locking handles.

Our 10-point locking consists of four shoot bolts, three mushroom headed espagnolettes, three hook bolts, a locking latch and a 6-pin euro cylinder. All our windows feature a multi-point locking system consisting of mushroom-headed espagnolettes which move in opposite directions into metal keeps. Why would you risk your possessions by using less?

Composite is a fantastic material to use for outdoor buildings and applications. It has all the benefits of plastic and timber combined, meaning it is very low maintenance, resistant to water, and highly durable. The external walls can either be left as supplied*, or painted to your preference using a Multi Surface Paint. We have used ‘BEDEC Multi Surface Paint’ for over eight years, and find it has fantastic adhesion, wear and colour fastness.

*Please note that unpainted/untreated areas of composite material may differ slightly in colour due to manufacturing processes. Because of this, paint may be required to address variations in panel colours, but this is subject to personal preference.

There’s no need to ‘duck’ on the way in through our quality uPVC doors. With a tall walkthrough height of 6’0″ (1.84m) you’re free to move in and out of your office concussion free. Others have tried to copy us but include the doorframe as part of their walkthrough height.

We can significantly undercut competitors offering uPVC options as we are a large DIY window and door manufacturer. We do not buy windows and doors from another company therefore we do not need to markup our prices and transfer the cost to our customers. Providing you with great value!

Grey exterior frames for your windows and doors will give a more contemporary feel to your garden office. We use domestic style uPVC for the frames of our office window and doors to add to the zero maintenance and long lasting overall effect of the structure.

Add a flyscreen to the windows of your garden building, so you can benefit from letting the fresh air in while keeping those pesky insects out, without restricting visibility. An insect screen will allow you to still view out of the window to survey your surroundings, watch nature and look out at the beauty of your garden.

As the effects of global warming take place, the Earth is changing, with reports suggesting an expected increase in the number of insects around the world. An increase in temperatures over the coming years will speed up the growth rate of some insects. This includes the domestic housefly, which could see a rapid rise in its population. Order your flyscreens now to protect you for the future.

Keeps out insects

It’s always nice to be able to throw open the windows of your garden room to enjoy a warm summer breeze or cooling air. With the addition of a flyscreen mesh, you can enjoy the warm weather without worrying about unwanted insects getting in. Keep those flying insects from buzzing around as you try to work in your garden office or relax in your summer house.

Ventilation and comfort

Ventilation and circulation of fresh air is also important for the wellbeing of you and your garden building and helps to maintain a relaxed and comfortable environment inside. Flyscreens for windows give effective protection so you don’t have the annoyance of flies and other creepy crawlies.

Durable materials

The fly mesh is made of strong and water-resistant materials to last. Easy to fit

It is provided as a simple ready to install screen to fit the size of your garden room or log cabin window and fixes to the window frame. Easy to follow instructions will be provided alongside your order.

Easy to use

The roller flyscreen is easy to operate, with a handle to pull it down when the window is open, and a small clip will keep the screen in place. When not in use, the retractable flyscreen design allows it to be discreetly hidden away.

You don’t need us to tell you how important it is to have a garden room that is easy to heat, and maintain at the right temperature. Our garden offices feature polyisocyanurate insulation in the roof, walls and floor, creating the perfect space to use as a home office or lounge room. Polyisocyanurate is arguably the best thermal insulation that can be found in any garden building in the market, especially when compared to the more commonly found Rockwool, polystyrene, or foil backed bubble wrap that competitors are supplying. It is known for being a far superior insulative material.

You may ask why did we go to such lengths to design a garden office with such high spec insulation compared to other companies. It’s really quite simple, we know that you will be spending most of your time in your garden office, either working or relaxing with the family, so it’s important to be comfortable and satisfied with your purchase. Our insulation helps retain the heat in the winter and keep you cool in the summer, meaning you can use your office all year round. The heat retention properties also help you spend less on your energy bills, by allowing you to not have the heating for on, longer than what’s needed.
