Extensions- 2 May 2019
I would like to say that Danny and his team did a fantastic job on the single storey extension to our home, they were very efficient and tidy during the whole build and kept us informed at each stage. I was very impressed with the speed in which it was completed, and the building inspector also commented on how much of a good job it was. Danny is very approachable and informative and added some really nice touches to the extension after consulting us which gave it that bit extra! some of his ideas I wouldn’t have thought of, I would not hesitate to recommend Danny, we are very happy and looking forward to appreciating their hard work.

I originally contacted Joe from Orama to fit a new kitchen for me. When he came to give me a quote, I hadn't yet chosen what I wanted. He really took the time to make several recommendations and so I decided to go ahead with him to design my kitchen fully and fit it. The team were so easy to work with and most importantly respectful in my home! Their attention to detail is second to none. He really understood the style I liked in one conversation. The finish is flawless. I highly recommend them!!
