Extensions- 9 Feb 2021
From the beginning of meeting Gareth and Tristan they are friendly and professional, they came to our home to build an extension and knock a wall down. They are an amazing pair. They are very skilled at what they do and they work continuously all day. They would clean up after themselves and were very unique with ideas for the build. If they came across an issue it was always resolved very quickly and affectly. They are very pet friendly as that can be a worry to pet owners when doing a big build. They also kept to their time scale even if that meant working late into the evening, but always arrived on time and were never late. Nothing is too much for them and it was a pleasure having them in our home. The result is spectacular and we are very pleased with what they have done. I would certainly recommend them to other people as they stand our from the rest.

George designed, built, installed a set of custom-made doors for under my stairwell. Lovely guy, very courteous and pleasant to have around, and the work was precise and pleasing. I had one or two tweaks I needed done to the doors after the job had been completed which he helpfully came back and did for me. Happy to recommend him.

Extensions- 13 Nov 2019
Mark managed the whole job (which was complex and involved three different rooms; change of use and new build) effectively and efficiently and engaged family members and friends in various trades as needed. With extensive experience Mark was able to make suggestions and put forward many ideas to improve the basic plans that we had which was most helpful. This included raising a ceiling level to a better height than we had envisaged possible and removing the need for a pier so that a wall could be flat throughout the new kitchen. Mark has a good eye for the aesthetics of a job. He is also very amenable to adding on extra smaller jobs in the process and even procuring some materials that I wanted in order to do something myself ! The workmanship and finish is high quality for a competitive price. I would not hesitate to recommend Mark and have, in fact, already done so for another couple of potential jobs. Finally, Mark is a really nice guy and great to have a chat and cup of tea with (two sugars!)

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

An extension builder in West Sussex 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?

Your West Sussex extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in West Sussex?

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 West Sussex extension builder’s ability to deliver a result that meets your expectations.
