Thermally Efficient Build

We offer garden rooms manufactured with the finest materials and latest manufacturing methods. This allows them to achieve a 21st-century thermal performance. The products within the design work to trap in pockets of warm air.

Even in the coldest winter months, your extension will retain heat, leading to you not needing central heating to warm the space. This will lead to low energy bills. As your energy consumption lessens, so to will the carbon footprint of your property.

Keeping the Elements Out

You won’t have to worry about our garden rooms letting the elements into your extension. The quality products we use within the design and the roofing profiles will keep out the changeable elements. Even in the strongest of Gloucestershire weather, you can have peace of mind that your home office is protected.

Even after constant exposure to the elements, our garden rooms will retain their quality. The colour is imbued into the design of the windows, doors and roofs. This means the Gloucestershire homeowner won’t ever need to repaint them.

The only maintenance our garden rooms require is for an occasional wipe down with a damp cloth. This will help to retain the look of your space. By choosing High-Tech Windows, you can have peace of mind you’ve invested in the best quality for your home.

Secure and Accredited

Each of our garden rooms are designed with our range of windows and doors. These products are fitted with quality locks across the frame. This will eliminate any potential weak spots that could be exploited by would-be intruders. This means the Gloucestershire homeowner can sleep peacefully knowing if they use the space for storage, they won’t have to worry about them being taken.

To ensure everything goes as smoothly as possible, our garden rooms are designed to be fully compliant with all current building regulations and planning permission requirements. This is providing the edge is within 2m of the boundary and the height does not exceed 2500mm, the garden room is smaller than 25 m2, and that half the garden remains free from garden structures. With this in mind, you can rest assured that everything is being handled to modern standards. Further to this, we’ll be able to offer minimal hassle to your daily life too.
