Alpha construction did a 2 storey side and roof extension, loft conversion, complete renovation, drive and patio for us. In short they took a dated 3 bedroom house and converted it into a modern 5 bedroom house. We invited over 10 builders to bid and Alpha supplied the most detailed quote and were the only one to meet each deadline. They were also always quick to answer questions. That level of customer service and professionalism was reflected in all latter dealings with them. They started on time, they finished on time. They updated us on a regular basis and found innovative solutions to unexpected issues e.g. inaccurate architectural drawings. They kept to budget and were transparent with costs. My husband particularly appreciated that they recommended value options or found lower cost solutions to our ideas. We also got access to a wealth of subcontractors. Ross put together a high quality team from the expected plumbers, electricians etc. To the unexpected such as window vendors / kitchen suppliers. All of which gave great value and high quality services compared to alternatives we found ourselves. Everyone at the house was polite and conscientious, in fact neighbours have been asking for quotes since. Since moving in we've had a lot of people comment on the great finish of the work they did. The house looks lovely and I would be happy to show others thinking of using them. I have recommended them to my friends and that's about the best compliment I can give.

Electrical- 26 Jul 2026
Genuinely one of the worst builders we have come across. David rewired the flat and Stefan plastered the hallway. David is NOT qualified as an electrician and cut corners wherever he could. David leveraged us for money mid job and in the end left the job without finishing and without providing a certificate. David ran cables behind door frames (awful idea), got the cheapest material, forgot where holes were for spotlights and switches among many issues which meant we had to constantly ask our builders to fill the holes and make good. Stefan did the hallway plastering without putting on mesh. The plaster cracked within 2 weeks and the paint keeps cracking and will be a constant problem. When asked to come back and fix the issue - he point blank refused. They were the cheapest quote but we really hope we had gone to someone else

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.
