Nick finds that inspiration can strike at any time. "I was thinking about the spheres I'd made from train tickets when I was walking down the street one day, and started looking at the estate agent boards on the houses. I had a eureka moment and realised I could use them to make a similar sphere, but much bigger and, ingeniously, it'd make a house. It adds to the statement that runs through my work about the waste and visual clutter in our world. It's also about homelessness, more sustainable methods of building, and property ownership."
