Double story, side and rear extension. Made the entire process a lot less stressful than it could have been. Excellent workmanship, completed the job on time, to budget and was both personable and professional. Great communication, and able to accommodate changes we made as we went. Highly recommended and have had back for further work since completion of the extension.

Extensions- 1 Feb 2023
We are in the last week or so of the extensive remodelling of the kitchen, utility room beyond plus bedroom upstairs. Mark Lomas and his team have been truly amazing, not just in exercising real building skills to blend the extension harmoniously with the existing Edwardian home but also in some imaginative problem solving as well. Costs have been spot on budget, save where I have caused additional work and fitting out, other than some unusual costs arising from some specialist joinery work which enabled the timber windows and doors to be exact replicas for others built 120 years ago. Honestly, I could not speak higher of the care and attention we have been given. I could get cross about the driving rain and the gruesome frosts and miserable cold, but that's a British Winter for you; Mark and his team certainly did not grizzle, and have stayed professional throughout. Circa £100k budget, so a reasonably size job and quite a risk for the builder - for my next project, I shall certainly use again in a heartbeat.

Joinery & Cabinet Making- 2 Mar 2018
Neil did an excellent job! We needed 5 oak veneer doors hung throughout the house including two bathrooms with the locks. He hung all 5 doors in one morning and then came back with a couple of willing assistants to fit the latches etc. a couple of days later. He cleaned up after the work very well and left the property very clean and no sawdust left. We are very pleased with the fitting and the doors all look lovely and can definitely recommend this firm.

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

An extension builder in Chesham 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?

What experience do you have with similar extensions in Chesham?

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