A great company to deal with, prompt, reliable and very professional. We live in an old Victorian house with hardly a straight angle anywhere. So Anunas had a tricky job to do. The job was done perfectly and to agreed cost. I would recommend this builder to you. If I could could give give 6 stars I would. Great job well done.

M&M Construction did a fantastic job and gave us exactly what we had wanted. From the start, they were easy to work with and understood our needs completely. Even with a few changes along the way, the job remained on schedule and on budget. Their advice was really helpful and the standard of finish was very high indeed. We had access to running water and a working oven throughout the entire process which was very much appreciated and the site was tidied at the end every day. Would highly recommend them.

BTR were awful. They delayed, double charged, installed the wrong items, left footprints on doors, and told me they had done the works when they hadn't. I was desperate for the works to be done properly as I was selling a house. They haven't paid me back the money I paid them to complete. I had to get someone else in because the standard was so low.
