“Lots of people build Lego. When I played with Lego when I was a child, it was ‘I have a whole load of Lego, what can I build out of it?’
“But Lego has increasingly become instruction-based, and you can make some incredible things. What I enjoy doing and seem, for some reason, to have an eye for, is recreating in Lego what people see in the street.”
The 55-year-old, who posts images of his creations on his social media pages alongside the real places that inspired them, says he mostly chooses not to reveal his identity because he wants the focus to be on the work.
But, in an interview with BBC Wales, he admitted he liked the nickname “Lego Banksy”, coined by one of the few friends who knows what he does.
“It’s not for any great mystery bit. I’m just me, I’m nothing for anybody to get excited about,” he said.
“But hopefully what I’m building does make people excited.”
