Exceptional Value, Superb Quality
We are known for providing exceptionally high-quality products at affordable prices. Be wary of competitors who offer lower-spec products, cut corners to save on prices and try to upsell you on necessary items such as flooring, roofing material and safety features!
To ensure the very best quality, we only use slow-grown White Spruce Timber, which is harvested in cold climates to ensure solid, dense log rings. This gives the wood superior strength and longevity, and a much more consistent colour than the likes of Pine.

This porch is under 3m high. Why does this matter? Under UK permitted development rights, porches under 3m can be constructed without planning permission*. In addition, this porch doesn’t exceed 3 square meters. If you want to find out more about permitted development, visit the planning portal.
*Please be advised that some exclusions may apply depending on property age, where it is situated etc. If in doubt, please check with your local planning authority.

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

Our porches are easy to heat, and maintain a warm temperature in the winter while staying cool in the summer. Our porches feature polyisocyanurate insulation in the walls, roof and floor, creating a warm and inviting entrance. Polyisocyanurate is known for being a far superior insulative material than the alternatives of polystyrene, Rockwool or bubble wrap.
Our porches are designed with a high internal eaves height reaching 2.11m. There’s plenty of room inside for people to walk around without bumping their heads and plenty of space making for a fully usable porch.

There’s no need for you or your guests to ‘duck’ on the way in through the door of the porch. With a tall walkthrough height of 6’0″ (1.84m) you’re free to move in and out of the porch with ease.

Get your porch installed quickly and easily thanks to the full panels provided. There is no need to waste time building up walls or fixing doors together.

Buy with greater confidence.
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


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.
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!

Whatever you choose to use your garden room for, security is important to keep all your treasured belongings and valuable items safe. This is why we include uPVC French doors with an industry-leading 12-point locking system, as well as multi-point locking windows with key locking handles.
Our 12-point locking system consists of four shoot bolts, three espagnolettes, three hook bolts, a locking latch and a 6-pin euro cylinder. Our window locking system consists of mushroom-headed espagnolettes which move in opposite directions into metal keeps.
