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.
