Landscaping- 22 Jul 2026
Thanks to the team we are set to have a fantastic summer in our new garden room and freshly laid lawn! Jack listened carefully to all our ideas and gave us a really competitive price. He took the time to create a bespoke layout, knowing all it would take extra effort, just to ensure it perfectly suits our needs. The quality of the finished build is top tier! Throughout the project, Jack proved to be a honest, trustworthy, and incredibly knowledgeable guy. His attention to detail and craftsmanship are second to none. He also patiently answered all our questions in detail. Like many big building projects, we hit some minor snags (roof drainage issues and a few delays). But to his absolute credit, he took full responsibility, came straight back to carry out the remedial work, actively suggested solutions to sort everything out. While scheduling can be busy in peak season, his commitment to doing the job right was what mattered most. We’re so satisfied and wish the team every success!

What to ask a Mirfield extension builder before hiring?

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

An extension builder in Mirfield 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 Mirfield 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 Mirfield?

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 Mirfield 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.
