Decking- 3 Jun 2026
Anthony did a great job from start to finish. Having had a few quotes, some cheaper, I decided to hire Anthony for the job as his quote was fair, thorough and clear about the process, materials, time needed, I did not get this assurance from some of the cheaper quotes. He listened carefully to what I was looking to do and make some good suggestions to help achieve the look I wanted for my decking. Communication was clear at all times during the job. Once the job started, Anthony was punctual each day, organised and ensured the site was kept clean at all times. I am very happy with the decking and standard of work achieved. I would highly recommend Anthony and AJK Building and would definitely hire him again for any future jobs.

Extensions- 4 Sep 2018
Chris and his team did a good job with the extension and we are happy with the completed room. Positives: The room was finished to a good standard. Chris was very approachable and happy to answer questions. He was willing to make adjustments to things we were not happy with. Good and competitive price. Negatives: Finished well over schedule agreed. Frustrating on day's when no one turns up and you do not know why. Some of the completed work needed to be modified / altered (Chris was happy to do this for no extra cost).

Conversions - General- 4 Jun 2024
I've been dealing with builders for the last 2.5 years and saw everything, I met so many dodgy people out there who say they know how to do things and eventually screw it up and disappear, that I lost trust in this industry, once I started to work with BBA Developments Ltd I noticed the difference straight away. Adam was professional and kind and explained everything to me. once BBA Developments Ltd began to work, I immediately noticed the difference: everything was done in a top professional way and everything was on time as promised and done to my satisfaction. There were no surprises during the project, there was a very kind contact who was always available to answer my questions quickly. I would recommend hiring BBA Developments Ltd without blinking.

Bricklaying- 6 Nov 2020
Tony gave me a competitive quote, not the cheapest but everything about him was professional and gave me confidence. His team arrived on time the day of the build and were helpful and pleasant. They worked all day and cleaned up and covered their work until they arrived on time the next morning. They worked hard all day. After the wall and piers were build all the brickwork and joints were left clean and crisp. I am very happy with the wall. I have renovated many properties over the years and the standard of this job was excellent. I highly recommend them.

Large job, internal building work (altering wall positions) and redesigning/refurbishing of two bathrooms in very old cottage. Well planned, managed and delivered. High quality and beautiful finish, work delivered to cost and scope (very slightly delayed due to additional reinforcements required to floors). Very pleased and would recommend.

Bricklaying- 27 Aug 2021
Mitch and his team were efficient at building the retaining wall in my garden, working on a Saturday to get the job done. The work was completed to a very high standard. The wall had to be left slightly unfinished in order for other works to happen first, so Mitch promised to come back and finish off the wall at no additional cost later in the week. After some chasing, Mitch came back to finish the wall by himself the following Saturday. This was also completed to a high standard. We would highly recommend Mitch’s service for an efficient, high standard output.

Extensions- 21 Sep 2019
Ray has done an outstanding job with the new extension. He has shown great attention to detail and accommodated every request. The result is one that we are extremely happy with. He installed a new bathroom downstairs complete with all necessary pipework and a new utility closet with exits for the washing and dryer. Clearly Ray has a very broad set of skills, from electricity to building to carpentry, plumbing and roofing. He really was the one stop shop to make this extension a reality and has a network of people he can call onto if required. He is certainly someone that takes pride in his work and wants a job well done as evidenced by his work. I recommend Ray without a doubt and I'm sure our paths will cross again. Thank you Ray!

Handyman- 29 Jul 2024
Robert gave a quote and came around to double check. We agreed a date, and later I re-confirmed about a week before, but he did not turn up on the day. I have not heard anything from him in over a couple of weeks despite a number of attempts to make contact, so I just presume he was not able to do the job. Disappointed at lack of communication and needless delay.

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

An extension builder in Baldock 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 Baldock 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 Baldock?

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

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 Baldock 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.
