Speaking to The Daily Mail, Neville said: "I used to bring architect's drawings with me. You have two hours on the way home on the plane. You can't sleep. You're wired. I'd make sure no one was sat next to me and I'd get them out. While Teddy and Dwight and that lot were playing cards, I’d be looking at drawings.
"I made loads of mistakes, spent too much money, changed designs all the time. But from rubble, we made it into this house and I was obsessed. I’ve still got three or four. My mum lives in one.
"For 10 to 12 years, I had this almost like a double life. I did it under the radar, purely because I knew that it would be deemed as a distraction. Under Sir Alex, distraction was absolutely illegal, you know that. But I knew that my football career would come to an end, and I knew that I had to plan for it, I knew that I had to do something different and I loved it. The meetings, the thrill of the interior design, the selling part of it, the finding the land, the planning."
