Single Storey Extensions

If you’re struggling for space in your South Wales or South West home, adding a single storey extension is definitely the way forward. Moving home causes so much upheaval and is massively costly, while extending your existing home can actually save money over the long term. What’s more, you can tailor your extension so it’s geared exactly towards meeting your needs.

We’re the experts when it comes to single storey extensions in Wales and the South West, and we’re so proud of our 100% satisfaction record. That’s because we’re a family-run business, and take the time to ensure all team members are fully trained and supported in their roles. What’s more, we only supply the highest quality products, and all our building work is backed by cast-iron guarantees.

More about our single storey extensions

We typically build single storey extensions at the side or back of properties, as this often means there’s no need for complex planning negotiations with councils. However, we’re committed to providing 100% customer satisfaction, so if you’re considering any type of single storey extension to your home, we’ll talk you through all the details.

Single storey extensions can be the best solution for growing families, and are a fantastic way to create links between the home and exterior living spaces. That’s another reason they’re increasingly popular.

 

And, finally, our single storey extensions maximise the amount of available light in any home. We’ll always incorporate our top quality UPVC doors and windows into extension designs, ensuring you benefit from significant levels of light throughout the day, no matter what the season.

      5 star review  Wonderful company from start to finish! I purchased a new door a few months ago, the quality and the fitting is outstanding. Having an old stone wall surrounding the fitting was not an easy job, however the result is to perfection. Being a family run business they take customer service to heart. I can not fault this company and would highly recommend it.

      5 star review  This small family company was excellent from start to finish. Then the after sales service was so efficient, Karl was at the end of the phone if the need arose. I would definitely recommend this company and would use them again.
