We hired Iain to complete a rear single storey extension, to create an open plan kitchen and living space. Iain and his team were very efficient and open throughout the whole build. The work was completed in less than 3 months. Iain was very approachable and informative about the process and decisions to be made, and offered expert opinions throughout the project. We have young children and Iain and his team were very accommodating to our family life and ensuring the area was safe! We are really happy with the build overall and the quality of work produced. I would highly recommend IML Building and I would definately use for future projects.

Extensions- 2 Jul 2025
We were really happy with our experience with YBF Pearson. The project was a single storey extension, and Rod project-managed it all from start to finish. He was always on top of what was going on, and communicated to us at every stage. We've never done anything like this before and so we didn't know what to expect, but we were really kept in the picture and were able to direct how we wanted things to be. The quality of the work is great, everything looks fantastic. We were able to have open discussions with Rod about budget and he was clear about what we could achieve for what we were willing to spend, and there were no unexpected costs or bumps in the road. Rod is a pleasure to deal with and overall we have come away really happy.

Joe did an excellent job on building a new concrete base for my new concrete shed which wasn’t a straightforward procedure because my patio is on a slope and carried out the work in a professional and polite way. The cost of building the base was reasonable and competitive and I would recommend him to family, friends and neighbours.

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

An extension builder in Castleford 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 Castleford 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 Castleford?

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