We employed Steve and his colleagues to do a extension above our garage plus extend the back of the house and build an Orangerie. The quality of work was excellent and I certainly have no complaints. It was slightly over schedule but bad weather paid a part in that at the early stages. However, the amount we paid at completion was exactly what we had been quoted at the start. It is a 4 man team and all of them are very polite and helpful and very willing to do anything extra that I asked. What I particularly liked was that there was usually 2 or 3 of them on site at any one time and not a day passed when there wasn't at least one. I know from friends who have had other builders in that this seems to be rare. When planning for our project we were very worried about choosing the builders due to so many horror stories. Steve provided me with 4 references, who I phoned and all of them had nothing but positives to say. As an added bonus of all the quotes we received they were the cheapest!! I would strongly recommend them and already have to my friends.

Extensions- 22 Dec 2025
We contracted JMD for a detached house project to demolish an old 1970s extension & rebuild larger 70sqm extension, an outside terrace patio and remodel some of our internal ground floor setup. Project started in Feb2025 and JMD made super quick progress on the build during the dry spring months. We had to pause JMD due to our timelines which they were fine with and finally completed end-to-end by Oct2025. What makes JMD standout for us was their team of employees – they don’t use too many contractors, most of their team are employed by JMD and are a loyal hardworking professional squad. Liam, Mark, Chip, Ross, Zac and the rest – all top class! We had some additional projects and requirements mid-project, JMD provided good pricing along the way which were all totally fair and priced as incremental add-ons. YES – there are always bits that could be better, but JMD did an excellent job on the whole. Site left clean, tidy, complete and all post project snags dealt with! THANKS JMD!

What experience do you have with similar extensions in Farnham?

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 Farnham extension builder’s ability to deliver a result that meets your expectations.
