Extensions- 24 Feb 2018
I first met Lee Buchanan when he came to give me a quote for a kitchen extension. He was extremely helpful and honest from the start. Given that I had a budget in mind Lee suggested that my husband and I meet with a QS first to give us a guide about how much the build would cost.(Over 5 years ago when we wanted to extend our building plans were accepted by the local council but then we struggled to get a builder to even give us a quote and when we did it was totally out of our price range) Lee spent time with my husband and I and suggested changes to help keep the build within our budget whilst still having a design we loved! Lee and Owen's (Lee's Dad) squad at OBB were very efficient , professional, helpful and friendly. The lads would go out of there way to explain things and were happy to do the extras in our build. My husband and I made some small changes along the way and each time Owen and Lee were more than happy to accommodate us. I also met with the OBB's office staff, Owen's wife and Lee's partner both of whom were very friendly and welcoming. Our main build has come to an end but we will be getting OBB back to do some extra work as we know we can rely and trust them to do a good and honest job. My husband and I would 100% recommend OBB.
