Landscaping- 10 Sep 2026
Louis made a difficult job very easy by sorting all the logistical problems of removing and disposing of an old patio and getting all the new stone and aggregate delivered where there was no easy access to the back garden. He worked continuous days until the job was done and finished in good time and on the budget we agreed, which was very reasonable. Louis did the job to the spec we wanted, including cutting mitre corners on narrow concrete edging, and was very clear when offering us different options, such as how to join the patio to the side passage. Everything was cleared up at the end, and the finished patio looks exactly as we had hoped it would. Louis was always polite and is a hard worker who takes an obvious pride in doing the job properly.

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

An extension builder in Greenwich 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 Greenwich 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 Greenwich?

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 Greenwich 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 Greenwich 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.
