Latest review:
Our garden had been pretty much unused since it was flooded in 2015. We had tried replacing the grass a couple of times ourselves, but it always died because of poor drainage due to clay soil. Michael dug out the whole area out and installed 2 french drains, improved the top soil and re-turfed the grass, laid some slate for a patio, and repurposed some existing paving slabs as a base for our shed, prolonging its life and saving us cash. The drainage has really worked, the water no longer sits on the surface and the lawn is flourishing! The patio area and the garden in general - has given our home another room. We couldn't be happier! Michael completed the whole job over 2 weeks - just like he said he would. I wouldn't hesitate in asking him to do further work for us, his workmanship is top quality.

Extensions- 22 Mar 2026
Rob and his team did an excellent job of my porch, the high standard of building work can be seen in his pictures and has attracted lots of interest . Even in wet, miserable weather, they turned up on time and worked a full day. Work was completed on time and to an exceptionally high standard. I would definitely recommend him and will use him for all future jobs. If you feel anxious about hiring a builder you do not know or inviting people into your home, Rob and his team are completely trustworthy. Rob is as honest as the day is long, professional and extremely hard working. He involves you at every step of the process and all choices are yours. There are no 'hidden' extras when he completes the work and he will not take advantage but will work with you to find the best option for your budget. He is more than willing to help with those small jobs that you think you should be able to do yourself, ie putting up baskets! without a thought! He is what a true workman should be!

Bricklaying- 5 Oct 2018
Thank you Patrick the job was completed professionally and on time. Patrick's work went above and beyond my expectations of how excellent the rebuild of a wall and installation of a window would look when completed. Patrick and his team arrived on time. I was kept informed of progress each day and Patrick and his team worked constantly throughout the day. They tidied up each day and on completion of the job. Patrick is very skilful and has great vision of how the work he does should look when finished. I would invite Patrick and his team to complete any future jobs as he is reliable, trustworthy and have restored my faith in the building trade after other no so nice experiences. Thanks once again for an excellent job, I am so pleased with the service received.

Built4u Developments have been a pleasure to deal with throughout the entire process of building our new home in leeds. William and his team are extremely professional, friendly and genuine people. They are punctual, reliable and proved to truly care about the quality of work that they produce. William has always been available for any queries we have had about the building process, and has been transparent about each stage of of construction throughout. William is extremely skilled at what he does, no task proved too big for him or his team, especially after seeing our stone and brick feature wall he told us to leave with him, which is a truly remarkable piece of art that he has built, which i am over the moon with, He also came up with several innovative suggestions throughout the house build process in order to improve quality of works, he has been brilliant. I would highly recommend Built4u Developments ltd for any renovation work, new build or feature work - we are so pleased that we decided to go with them out of a long list of construction companies in West Yorkshire.

What to ask a Birstall extension builder before hiring?

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

An extension builder in Birstall 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 Birstall 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 Birstall?

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 Birstall 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 Birstall 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
