My relationship to plants becomes closer and closer. They make me quiet; I like to be in their company.

I work a little bit like a sculptor. When I start, my first idea for a building is with the material. I believe architecture is about that. It's not about paper, it's not about forms. It's about space and material.

Designing is a matter of concentration. You go deep into what you want to do. It's about intensive research, really. The concentration is warm and intimate and like the fire inside the earth - intense but not distorted. You can go to a place, really feel it in your heart. It's actually a beautiful feeling.

The first 10 years of my professional life had only to do with running away from my father. He was a wonderful cabinet-maker, and me being the eldest son, I had to take over his shop, his profession and so on and so on. I tried to escape by going to art school and then going on to industrial design and then interior design.

But if somebody wrote Delphi a big check for these plants, I am sure the company would jump at it.

There is still a real need for good quality architecture, not paper architecture, but the real stuff.
