We hired Tony, TDA Builders, to remove a load bearing wall in our timber frame house. After being let down by other contractors we were relieved when Tony responded and came round to estimate the work on the day and time he promised. His quotation was very detailed and precise and within our budget so we asked him to do the work. What a very pleasant person to have working in your house, professional, respectful and very clean and tidy and very knowledgable. His work was to a very high standard and he started and finished on time. I would have no hesitation asking him to undertake further work or recommending him to anyone. What an excellent job.

Extensions- 27 Jul 2023
I would be happy to use RDS buiding services again. They turned up every day worked efficiently and kept the mess created by the construction out of the way of the neighbours. The budget we agreed was followed and the stage payments schedule worked throighout the build. I am very happy with the quality of the work and more importantly the attitude of the builders who worked with us when inevitable snags came along. We invited RDS to do some additional work (landscaping in the garden) which did not detract from the main job. Thanks RDS for a job well done.

Extensions- 2 Aug 2023
JLita construction were hired after a competitive quote was agreed to carry out work on my kitchen extension project last year. Prompt and dependable Jetmir’s team worked productive long hours with a clear understanding of my wants and requirements. Where it was possible to accommodate they did. Any remedial work was quickly picked up and completed in good time to the required specifications. After completion of work each day, the space was swept and tidied and the space made as usable as possible. I am extremely happy with the work carried out and the attention to detail applied by Jetmir and his team and would, (and have already) happily recommend JLita Construction for any building works. More than satisfied. Many thanks Jetmir and team. Scott

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.

David McGill from Dm Brickwork and his team built a Garage on the side of my house for me they have done a fantastic job exceeded my expectations. The guys are really nice friendly and professional. They helped my disabled wife move her car in and out of the drive as she couldn’t and even helped her in with the shopping. I will be asking them to come back to build a patio in the future and recommend them to anyone that needs building work done.

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

An extension builder in Dunstable 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 Dunstable 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 Dunstable?

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 Dunstable 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 Dunstable 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.
