Extensions- 21 Jul 2021
Top Tip - Engage Andy to do your work! We were delighted with the work Andy and his team completed on this new extension. Andy was on site throughout the build. His and his teams experience with this sort of work ensured that there was always a solution for minor problems and the advice they offered on light/space/design was invaluable. Despite the general increase in costs and shortage of materials during this pandemic, Andy brought the whole project in on time and within the original budget. His team worked well together, were polite and friendly and ensured that they understood the requirements and level of finish we were trying to achieve. In short - on time, on budget and a quality job. Can't recommend him strongly enough.

Extensions- 29 Dec 2024
Dave and his team completed the work on our extension on time and within budget and have done a fantastic job. They are highly skilled, reliable and very organised workmen and easy to get along with. Through out the project they were very punctual, always arriving on site and ready to start work at 8:00am from the very start until the completion handover. They were very tidy through out the project and always put their tools away at the end of the day. They also ensured that the site and road of the front of the house where kept clean and tidy. Our neighbours mentioned that they where always polite and how clean they were. All work completed was to a high standard and anything that we highlighted that we were not happy with was rectified quickly. The team where constantly asking questions on different aspects of the build to ensure that the end product met our expectations. I would highly recommended Dave and his team to anyone looking for a competent builder.

Extensions- 26 Apr 2019
I cannot recommend Nick and his team highly enough. They have been absolutely amazing throughout our extension. They’ve just completed a double side extension, with a rear single extension and totally reconfigured our upstairs by moving the staircase. They were respectful of our house and neighbours throughout the build and the site was always clean and tidy. You can clearly see that Nick thrives off a good reputation. He kept us informed throughout the build and was quick to problem solve any issues that arose without any fuss. They worked tirelessly to complete on time, working long hours towards the end. I have heard so many horror stories from people about builders still working on their extensions months after the agreed completion date or just not showing up for days at a time. Nick and the guys are the complete opposite they were there 8am every morning. The build has honestly been surprisingly stress free. I am amazed at how quickly they completed our project and to such a high standard. I would recommend Nick and the team to anyone who is looking at building an extension. Nick is competitive on price and there were no hidden extras in the quote. Thank you Guys for our lovely new home!

Loft Conversion- 3 Jun 2024
I interviewed 8 builders to do the work, they were all given a very comprehensive schedule of works so everybody new what needed doing. The prices varied massively, Wesley quoted somewhere in the middle and had a good atitude to how the work was going to be done. We had a few problems arise which he and his team worked through and managed to get the results we wanted. I am very pleased with the outcome and the total cost was very close to the quote, he completed the work in the time quoted with just a bit of snagging to do afterwards.

Extensions- 8 Jun 2025
We are really pleased with everything Jamie and his team have done. Throughout the process all of the team were polite and communicated every stage of the build. Jamie made some suggestions on what would work well with our new project and we are so glad we went with him suggestions (they look great). When Jamie came to quote for the job, it came back quickly and had a break down of everything. We were able to see how much every stage of the project was going to cost and we could add or do some work ourselves. All the team were very knowledgeable and there was no pressure to go for a certain brand or kitchen, which we did have from other builders. Overall we would highly recommend Jamie and his team.
