Extensions- 4 Jun 2022
Danny designed and built us a garden room to fit a challenging space at the bottom of our garden. His communication from start to finish was excellent, and he did an brilliant job on the room, inside and out. I would recommend Danny for any job, big or small.

Extensions- 1 Sep 2021
I have nothing but praise for Michael and his team. The project was managed exceptionally well and Michael kept us apprised of progress, emerging issues (which were dealt with quickly and with some innovative thinking) and he was honest and candid with our choice of kitchen tile (I think his words were do you want to rethink that colour!). Michael quoted in Nov and started work in the Spring (late Mar) and held his price despite a national increase in the price of materials and reduced availability which he managed admirably. Obviously a man with a good eye; his suggestions for additional works were inspired and they have resulted in a high quality finish. Finally, it is worth mentioning the team who did the grafting! Very industrious, skilled, polite and helpful. Highly recommend Wooburn PM to anyone considering building work. :-)

What to ask a North London extension builder before hiring?

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

An extension builder in North London 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 North London 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 North London?

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 North London 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 North London 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.
