Extensions- 17 Apr 2019
We can't recommend Vince and Swift Design and Build highly enough. Vince made the impossible possible! He arrived on time and left the site clean and tidy at the end of every day. Vince had great suggestions to tweaks and changes we could make when problems arose, making us feel at ease during the whole project. We are very pleased with the end result and will definitely be recommending Vince to others. Thank you Vince!

What qualifications and experience do you have as an extension builder in Horley?

An extension builder in Horley should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Horley?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Horley extension builder’s ability to deliver a result that meets your expectations.
