Olly Hayden
I got Lee and the team to help build a new internal room in our house. I have to say that the job was both excellent and the communication was great. I didn't have any issues and would both go with them again and recommend for others.
Lorraine Hackett
Lee and Designroom did a single storey extension for us last year. I cannot recommend her highly enough. Throughout the process, my expectations were exceeded. Communication was excellent throughout and the quality of work was second to none. The entire team were delightful to work with and we are extremely happy with the result.
Rach Kane
Recently got a kitchen extension from Lee. Absolutely top class service throughout the whole project. Lee always kept me up to date on construction and any questions I had were answered efficiently. I couldn't recommend Lee & the team enough.
