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.

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.

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.

      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.

      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.
