Extensions- 5 Jul 2026
We would recommend Dylan and his team to anyone, we can't be more pleased with the outcome. Throughout the build we've had regular conversations and updates. We had some unexpected issues to deal with (uncovered a Well while digging the footings) but the team managed it brilliantly without delaying the biuld. The quality of work has been excellent, they took real pride in every detail. they were also a pleasure to have around our home, very respectful and considerate. If you've looking for a builder that takes pride in their work then I would definitely recommend Dylan and his team, any work in the future will be offered to KS Construction.

Kitchen Fitting- 12 Jan 2026
No rating. Be careful of him. We were really unhappy with him. We had agreed on a price. He had made a leak in the radiator, left tenants without heating and hot water. I had to get my own engineer. We paid him and he left the job uncomplicated. Tenants without a kitchen, no gas no water. Really unhappy.

What to ask a Derby extension builder before hiring?

Before hiring an extension builder in Derby or extension building company in Derby, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Derby 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 Derby 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 Derby?

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 Derby 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 Derby 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.
