Groundwork & Foundations- 22 May 2026
John did a fantastic job with the groundworks for our new 150sqm block driveway. He priced keenly, started quickly and was on-site consistently every day for the week. Really skilled with the digger, good at dealing with the neighbours and always fun to talk to. Some aspects of the job changed based on what the dig uncovered, but he was pragmatic and ultimately left me feeling that he just really wanted to do a good job as if it was his own. Highly recommended - 10/10.

Extension Builder in Barnsbury
We renovate, decorate and repurpose buildings to make sure they fully meet your needs. By regularly working with homeowners and landlords, we ensure your property renovation is completed to the high standards you’d expect and is exactly what you need it to be. Having worked in renovations for many years, we understand that it’s not about the amount of work you require. It’s about taking ownership of the space, making it yours and building it up around your requirements and expectations, so you can do exactly what you want with the building. We can redevelop and remodel a space so you can start afresh, or provide a more cosmetic refurb to give your property a new look. Our flexible approach allows us to take on refurbishment projects of all sizes and do every building justice. Regards

Very happy with the extension. Eddie and his team were best priced which was the reason we went with them, and he brought in a crack team of brickies, roofers and notable mention to the tilers.

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 Barnsbury extension builder before hiring?

Before hiring an extension builder in Barnsbury or extension building company in Barnsbury, 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 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.

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 Barnsbury 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.
