Extensions- 3 Jun 2025
From start to finish, Connor, Andrew and their team at Biggin Renovations Group Ltd provided exceptional service. We had a double storey side extension and garage connection to the house that included 2 new bedrooms and an en-suite completed. The team confirmed a 12 week timescale, and a week by week expectation of work to be completed, along with the payment plan which was all confirmed via contract. They stuck to their time schedules and completed on time. The price was within our budget. Along with Connor and Andrew, their team of subcontractors were very kind, helpful, polite and professional in the way they presented themselves. Very happy with the work that was completed, we will call them for our planned single storey extension in the near future. Highly recommend them.

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

An extension builder in Barnsbury 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 Barnsbury 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 Barnsbury?

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 Barnsbury 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.
