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.

Architecture is not about form

You feel a certain way in a glass or concrete or limestone building. It has an effect on your skin - the same with plywood or veneer, or solid timber. Wood doesn't steal energy from your body the way glass and concrete steal heat. When it's hot, a wood house feels cooler than a concrete one, and when it's cold, the other way around.

I think the chance of finding beauty is higher if you don't work on it directly. Beauty in architecture is driven by practicality. This is what you learn from studying the old townscapes of the Swiss farmers.

Every time I imagine a garden in an architectural setting, it turns into a magical place. I think of gardens I have seen, that I believe I have seen, that I long to see, surrounded by simple walls, columns, arcades or the facades of buildings - sheltered places of great intimacy where I want to stay for a long time.

I've said goodbye to the overworked notion that architecture has to save the world.

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.
