Extensions- 19 Dec 2017
Richard and Andrew were excellent from beginning to end. The estimates were accurate and they came in on budget and finished on time. The work was done to an excellent standard with great attention to detail and no cutting of corners. They were considerate and helpful and tidied up at the end of each day. They were also friendly and we had many comments from our neighbours about how friendly and pleasant they were. They were also very helpful with last-minute changes that we needed and made suggestions for how things could be done better and more cost effectively. They even looked after our dog during the day, letting her out when we were not home. I would recommend R. Naylor Construction if you need a good job done to a high standard by someone who is friendly, knowledgeable and considerate.

Extensions- 20 Apr 2023
We employed Phil (and Dave) to build a porch extension for us. Phil coverered all aspects of the work, from the initial chat to find out what we were after (there were no plans), to foundation digging, brick-laying, a bit of knocking through with insertion of the required lintels etc, to basic electrical and right through to plastering. All completed to a high standard and desigtned to fall within the remit of permitted development. I wouldn't hesitate to recommend Phil, and would put him top of our list of local builders if we required any further work completing, big or small. He is obviously a very experienced builder.

I cannot recommend AJR Construction highly enough! From beginning to end Adam has been brilliant. The work that he and his team completed was delivered to an excellent standard but on top of the first rate workmanship Adam’s communication with us was great throughout. He helped to guide us through the process and practicalities of doing a big extension with understanding and patience which, for first time renovators, was invaluable. It was a pleasure having Adam and Dion at the house, I’d recommend them in a heartbeat and I wouldn’t hesitate to use them again.

What experience do you have with similar extensions in Buckinghamshire?

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