Our home refurbishment and extension are now complete and we are unbelievably happy with the final result. A1 realised our dream. We would recommend them without reservation. Having previously wasted hours and spent too much money with architects and potential builders, we were recommended to consider A1. From the very start, Steve Mills and Rikki-Lee understood our ideas and skilfully suggested possible additions to our project. A1 took control of everything from drawings, planning permission and build, allowing us to feel involved and reassured about our home development. The building team were

We recently used A1 for our rear extension and are extremely happy with the results. The builders and project managers were all very hard working and pleasant to work with. Any small problems that we had were very quickly resolved with no issue whatsoever. This is the second time that we have used A1 as their standard of work and efficiency was so good on our loft extension 7 years ago we were very keen to have them back again. Their original quotes for both extensions weren't the cheapest that we had but the quality and speed with which the work was done was well worth the money. I highly recommend

We engaged A1 to build a loft for us. The team they provided has been top notch. Darryl as team lead with his main man Peter makes a very good team. They were able to complete the entire project in under 7 weeks. This has been really impressive. Darryl was really good with communicating the various stages and very detail oriented. There were the usual challenges of coordination, but it was very effectively managed. I would also make a special note of how courteous the entire team has been. All in all very happy to recommend A1 and Darryl's team to anyone looking for building a loft.

I was dreading starting the loft but our A1 Project Manager was absolutely brilliant. They were courteous, helpful with ideas and hoovered up every night! They were so efficient it was hard to keep up with them at times. Even now almost 12 months on they come back if anything crops up that needs attention. I would strongly recommend using A1 to anyone who asks.

A1 have produced a beautiful loft for us. The work of the build team was excellent and overall we are very happy with the build. This would have been a five star review had it not been for a couple of shortcomings. Firstly we had asked for design involvement in the stairs. This didn't happen and I feel A1 as the project management team take responsibility for that. Secondly there were issues with the scaffolding that was left in place for too long. However having said that the build was done beautifully and we are extremely happy with the results overall. I am happy to recommend them. The team
