Extensions- 29 Jul 2018
Working with Louis has been a delight. From the very beginning he has been completely professional. The quality of the work is fantastic, Louis thinks of things that I did not even consider. The costings were accurate and when there was a variation it was priced immediately. Louis passed on any savings he made in the final account. Louis managed the project, dealing with all aspects of building control and sub-contractors, with a shout out to Pete who was also highly skilled. Probably most importantly Louis is completely honest and trustworthy, he does what he says. Overall, I could not be happier, the outcome far exceeded my expectations. I would not hesitate to recommend him.

Extensions- 2 Jun 2019
We're absolutely delighted with the quality of Ark's work. They demolished a double story section of the property brick-by-brick, which made up approx 1/3 of the property. They then rebuilt this, added a side return in fill extension, and completely refurbished the interior of the whole property, which was a shell, all to a brilliant standard. Lee and Tony clearly take real pride in their work, which gave us huge confidence that we were in really good hands and we could trust them to do the right thing. You can tell the level of experience they have as they just know what works and often came up with cost effective solutions or suggestions about how to overcome any tricky parts of the build, often taking the initiative on more complex technical parts of the build without constantly asking questions of a busy family. The initial estimate was clearly laid out in a step-by-step manner so we knew exactly what we were paying for and they were the most reasonably priced of all the builders we got quotes from. They were also able to source materials at reasonable prices. We had a very difficult neighbour that they handled brilliantly, which took a huge amount of stress off our family. Indeed our other neighbours commented on how respectful they were always cleaning up after themselves. I couldn't recommend Ark highly enough if you want a trustworthy, reliable firm who are reasonably priced and take huge pride in their work. You'll definitely be happy with the results.

Conversions - General- 15 Feb 2026
Mike and Miles were brilliant, they explained everything well and completed the work on time while involving us in decisions throughout. They visited to quote for the cooker opening and after this, we also asked them to fit a new sewage pipe. As we’re doing a full renovation they also helped answer questions around the rest of the house, teaching us a thing or two! We will definitely be using them again!!

We were really pleased with the work Guy did for us - both jobs were completed swiftly, to a high standard, and at a very reasonable cost. Guy was easy to contact/communicate with and kept us up to date with progress on a part he had to order. He was punctual - and came when he said he was going to come. I'm glad we have found Guy as we will definitely use him again for other work :-) Thanks again Guy!

Groundwork & Foundations- 23 Mar 2020
I hired Mac as I felt I could work with him and not have him just working for me. Both he and his partner Ed were very conscientious and thoroughly accommodating in their work. Although my build was only a large ‘shed’ base it was treated with the same reverence as any other house extension. The work site was restrictive, as most was taken up with the project, and access for materials, skips and concrete was limited, creating logistical problems which they overcame admirably. The machine control in the enclosed space was exemplary and showcased Mac’s expertise with the digger and Ed’s on dumper. The standard of work was excellent, maintaining a clean site at all times as best as possible. Both showed the utmost respect not only to us, but also to our property. The lawn was covered to minimise damage, and disruption was minimal. I will definitely be asking Mac to quote for my next project, a block paving driveway. I would recommend them, even to friends :)

What to ask a Bath extension builder before hiring?

Before hiring an extension builder in Bath or extension building company in Bath, 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 Bath?

An extension builder in Bath 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 Bath 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 Bath?

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 Bath 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 Bath 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.
