Guardian Home Extension

The Revolutionary Home Extension System

An extension can transform your home, allowing you to reconfigure internal layouts and bring in more natural light or simply provide extra living space. The Guardian Home Extension offers a revolutionary alternative to a conventional brick and mortar extension, dramatically reducing build times whilst achieving the highest standards in energy efficiency.

Expertly constructed with fully insulated roof and walls, double-glazed windows and strong, reinforced structures, a Guardian™ Extension is the affordable alternative to a traditional brick-built structure.

Make Space for Living

Creating the perfect home for you and your family is something that everyone wants to achieve, and quite often we simply need more space or a different configuration to release the potential of our homes. With outstanding thermal efficiency, wide ranging design flexibility and efficient build times, the Guardian Home Extension is the revolutionary and modern method of construction that is transforming homes across the country.

Benefits of a Guardian Extension

The Guardian Home Extension is a revolutionary, advanced energy-efficient home extension that can transform your house into the home you have always dreamed of. Installed in just 3 weeks,* the Guardian Home Extension is low fuss, low disruption and will enable you to have that extra space for living in far less time than a traditionally built extension


The Guardian Warm Wall is less than half the thickness of a traditional cavity wall that achieves the same thermal value. Significant internal extra space is automatically created with the Guardian Home Extension.

Energy Efficiency

The Guardian Home Extension uses high performance insulation systems and has been tested and proven to reduce energy costs compared with a traditional build extension.

Peace of Mind

The Guardian Home Extension has been independently and rigorously tested by the Building Research Establishment (BRE) with the Guardian Warm Wall featuring the Kingspan TEK Building System being certified by the BBA (British Board of Agrément).

Speed of Build

The Guardian Home Extension is fully offsite manufactured and supplied in kit form, eradicating waste and reducing disruption usually experienced with traditional builds. Construction is up to 5 times quicker than a traditional build and can continue in any weather.


Each Guardian Home Extension is engineered precisely to your individual requirements and pre-assembled under controlled factory conditions to ensure the highest quality.

Design Flexibility

The Guardian Home Extension is a flexible system allowing you to design your perfect home extension system with a range of roof types, shapes, sizes and finishes available.

Most of the construction work is done off-site meaning the complete system is delivered to site ready for installation. The final extension is completed in a fraction of the ‘on-site’ time and at a lower cost than a brick and block built alternative.

Each building is designed and constructed on a bespoke basis, so if you have an idea of the sort of thing you want, or even if you haven’t, please contact us so we can talk you through the process.

Advanced & sustainable technology for superior thermal performance

Creating your family home is about creating warmth – a space for you and your family to relax and play and to create the memories of a lifetime. A Guardian Home Extension will enable you to create the perfect extension and make your home complete. It’s also been developed with warmth in mind, combining the most advanced and industry leading thermally energy-efficient construction methods, keeping you and your family warm and your energy costs low.

Ensuring your new extension is well insulated and uses energy efficiently is a key priority. That’s why the Guardian Home Extension is constructed using the highly insulated and innovative Kingspan TEK® Building System, coupled with the market leading Guardian Warm Roof system. Both systems have been rigorously tested to ensure they exceed the required thermal performance set by building regulations.

The Guardian Warm Wall will comfortably achieve a thermal performance U-value of 0.18 W/m2k once fully constructed with interior and exterior finishes. To achieve the same thermal performance from a traditional brick build construction would require a wall thickness almost double that of the Guardian Warm Wall.

Having enough space for all the family is vital to ensuring a harmonious and happy house. Space creates that freedom of choice to relax, socialise, study and play when you and your family wish. Adding an extension to your home will allow you to reimagine your living space just the way you and your family want it. Not only will your new extension provide you with a fantastic new space, but it will also allow you to free up other areas of your home enabling you to optimise and bring harmony through the whole house. The Guardian Home Extension, with its innovative Guardian Warm Wall technology, further maximises the sqm floor space vs traditionally built extensions.
