Extensions- 3 Aug 2020
We worked closely with Harpreet, our Architect and Building regulations to achieve the dream kitchen and living space. It was a lot of work and sometimes we thought it would not finish or look how we wanted it. But Harpreet came through in the end and we are pleased with the work that was done to complete our single storey extension.

What to ask a Barbican extension builder before hiring?

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

An extension builder in Barbican 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 Barbican 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 Barbican?

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 Barbican 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 Barbican 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.
