Very professional and easy to work with. I would highly recommend John McCay and his company, his attention to detail was excellent.Read More

I'm about a year in with John and we have our planning submitted and all, we are due to hear back in the next few weeks as too the decision. John has designed a couple of houses for my family and all have a good word for him. very professional and respond usually within minutes of any query. This is my first and hopefully only house i'll be building. John has kept me and my wife on the right course so far. We have chopped and changed here and there but nothing has been troublesome for John, we have also stressed this could be a long term project as appose to the usual 1-2 year turnaround most try to achieve, again all was good and totally relaxed approach. I look forward to getting the build underway and feel like I have made the first important call by appointing John as my architect.Read More
