Architecture- 17 Sep 2025
Overall we are happy with the work that has been done, however the whole experience has been soured by the fact that I am still chasing to have the new hot water cylinder properly commissioned almost 2 years after installation meaning I cannot have it serviced and won't be able to claim on the warranty if things go wrong. My home insurance will also not pay out on any damage that may be caused. The other issue is that the two consumer units that were installed have not been labelled so I have no idea which breaker does what, this is a safety concern. My many attempts to contact Mandeep about this have been fruitless, I'm just being ignored.

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!!

Extensions- 24 Mar 2021
Rhys and his team have good skills and quality on all the extension works including big/long steel beam installation, extension connecting to the existing structure, complex loft conversion and architectural curve hung ceiling. For the internal decorating, they completed a beautiful bathroom for us. The staff were polite and friendly and also provided technical suggestions to optimise the design time to time. I would recommend RJB for similar size extension construction projects and decoration work.
