Bungalow Transformation with rear extension and complete renovation
"We were recommended Alperen by a friend, and it’s easy to see why. He really listens to what you’re trying to achieve and puts a lot of thought into his designs. Our ground floor extension plans turned out even better than we’d hoped, and we’ve since passed his name on to several friends too."

2) Changes to these Terms

We may update these Terms from time to time. The “Last updated” date shows when changes were made. Your continued use of the Site after changes means you accept the updated Terms.

3) Using the Site

  • You must use the Site lawfully and not misuse it (for example, by introducing malware, scraping, or trying to gain unauthorised access).
