Extensions- 4 Jul 2026
We posted our building project on MyBuilder for the construction of a new outbuilding. We received a number of responses and quotes and selected EDSS Ltd. My elderly mother had used EDSS Ltd previously to do a number of renovations to her house and we found EDSS Ltd’s quote competitive and fully broken down. The work completed to date has been high quality with a high level of attention to detail. Stefan and his team managed the project from start to finish. This has included liaising with building control and other parties. We did not have to worry about any detail and Stefan always goes the extra mile to reduce any inconvenience. Stefan and his team were reliable, hardworking, approachable and always willing to discuss any questions we had during the build. The work was completed to a very high standard and we were kept informed throughout the project. We have no reservations in recommending EDSS Ltd and are happy for customers to see the work.

What to ask a Sydenham extension builder before hiring?

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

An extension builder in Sydenham 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 Sydenham 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 Sydenham?

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 Sydenham 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 Sydenham 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.
