The main source of my income is through the commissions of the large-scale works and big sculptures, the projects.

When it does get below freezing and there is - it's cold enough for ice to form, then that changes the whole landscape, and it makes the landscape a different landscape to the one that I worked with previously. And I want to understand that. But the big tension of the ice works is that they're often made when it's cold enough to freeze one piece of ice to another.

When I make a work, I often take it to the very edge of its collapse, and that's a very beautiful balance.

Design implies a sense of mapping something out and then you follow the plan.

I have worked with this red all over the world - in Japan, California, France, Britain, Australia - a vein running round the earth. It has taught me about the flow, energy and life that connects one place with another.

When I was at art school, a lot of art education is about art being a means of self-expression, and as an 18-year-old I didn't know if I had a huge amount I wanted to express. It was a big moment when I decided I wanted to shift the emphasis or the intention of my art from something I disgorged myself upon and something that actually fed me or made me see the world or understand the world.

The British climate, although it is very wet, it is quite mild in winter. We don't get these severe - generally don't get severe winters.
