Groundwork & Foundations- 14 Mar 2019
I had no idea what was required for this job. However Mike from Pestridge construction knew exactly what was required and gave me all the options. I chose and because the work was 'minor' he was able to source the material and complete the job later that day. Perfect.

Carpentry- 25 Feb 2021
Hiring Kyle for our project was the best decision we made. We had undertaken a self build and Kyle acted as both our site foreman and an experienced chippie. He helped us build a unique house even though there were a lot of logistical challenges.I would not hesitate recommending Kyle to anyone he's an extremely diligent and professional carpenter who has great attention to detail.

After being let down by two previous builders I cannot recommend Mark and his team highly enough, they started when they said they would, were polite and courteous to my neighbours and I was constantly updated on progress, everything was left tidy and the project was completed on time and the quality of work is excellent. I will definitely be using Mark in the future.

ONR are extremely professional, and totally focussed on attention to detail, to ensure that their clients are completely satisfied with their work. All their team are meticulous in the work they undertake, and are very tidy, whether working outside or inside. To say they are perfectionists really underplays their attitude to a job, and the regular communication with the client is always informative. Our job had a number of technical challenges, but ONR worked through each problem with total professionalism, always discussing the issues in detail, and securing our agreement to the solution, before proceeding. I would have no hesitation in recommending ONR , and would happily use them again Charles Hollinsworth

Andrew of Kaldien was very quick to respond to my job. He went out of his way to visit our home out of working hours. He found the fault very quickly and luckily we only had to incur the call out charge which included half an hour's labour. The fault is up and running again and we couldn't be happier with his work. Will definitely be using Andrew again.

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.

Plastering- 16 Oct 2024
Ben and his colleagues have done a brilliant job of re-rendering the outside of my house in South Warwickshire. I really can't fault the team's work. They were all very keen to ensure that we were happy with the work. The project was undertaken in some challenging weather conditions at times and we did have some delays as a result. Communication was excellent. We always knew what was happening. I would very highly recommend BespokeBuilds to anyone needing rendering or plastering. Excellent!

What to ask a Swindon extension builder before hiring?

Before hiring an extension builder in Swindon or extension building company in Swindon, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Swindon 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 Swindon 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 Swindon?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Swindon extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
