I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.

Groundwork & Foundations- 26 Feb 2025
I hired John to build a concrete base for a garden building installation and he did a great job, resulting in follow-on work for him laying a new Indian sandstone patio in front of the building, which he also did to a high standard. After receiving several quotes from different firms, I selected John because he asked the right questions, clearly thought about the solution and was interested in ensuring the result was the right one right for me. He's a lovely bloke and a pleasure to have working here. He works on his own and for the most part keeps himself to himself, wasn't fussed about tweaking the scope here or there as the plan developed and kept the place pretty tidy throughout. I will be using him again for sure, so I wholeheartedly recommend John for any work you're considering hiring him for.

We’ve had multiple jobs done by Silviya. The first was a small extension and downstairs and partial upstairs refurbishment with new kitchen and 2 bathrooms fitted. This large job was completed within 16 weeks and looks exactly as we hoped. Given the extent of works we moved out for the build. The second was the construction of an outbuilding and garden redesign (patio and astro fitted). Again the results are great. We lived in during this project and I worked from home without disturbance. The latest has been the re-fit of new windows, front door and fixing the front render. Again, the results are very professional and minimal disturbance while the work took place. Will definitely use him and his team again, should we need any more building work and recommend them to others

Tom Reilly recently fitted a kitchen for me and I am very pleased with the result. The work he has done cannot be faulted. Tom was reliable and came when he said he would. He was efficient and very clean and tidy. I would highly recommend Tom and I am, in fact, hiring him again to do further work for me.

Hard Flooring- 2 Mar 2026
Highly recommend Kaylum, he ripped out the old sub-floor and fitted a new sub-floor along with new Engineered wood flooring in all of the bedrooms and hallway. Quality of work and attention to detail was exceptional. His colleague then decorated all the rooms beautifully once the floor was installed - really happy with the end result.

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

An extension builder in Banstead 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 Banstead 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 Banstead?

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