I admire anyone that follows the road less travelled.

I am a big fan of long drop, composting toilets - I like the cycle of using waste. When you have experienced one and seen what comes out of the bottom, it is amazing stuff. It's the most beautiful, driest, sweet-smelling compost.

The thing that I champion is sustainability. My terror is that suddenly we see it as a luxury, not an essential. That's a danger.

I'm really quite conscious of clothes and the way they fit and don't regret wearing anything. Not even the five-inch stack heels I wore with three-button high-waisters at comprehensive school. Regret is for wimps.

I was never a hugely successful theatre designer. I painted a lot of scenery and did the lighting, and my lighting business grew out of that.
