I am convinced that a good building must be capable of absorbing the traces of human life and taking on a specific richness... I think of the patina of age on materials, of innumerable small scratches on surfaces, of varnish that has grown dull and brittle, and of edges polished by use.

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 think space, architectural space, is my thing. It's not about facade, elevation, making image, making money. My passion is creating space.

When I concentrate on a specific site or place for which I am going to design a building, I try to plumb its depths, its form, its history and its sensuous qualities.

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.

My buildings should have an emotional core - a space which, in itself, has an emotional nice feeling.

Architecture has its place in the concrete world. This is where it exists. This is where it makes its statement.

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.

If you're lucky, and a building succeeds, the real product has many more dimensions than you can ever imagine. You have the sun, the light, the rain, the birds, the feel.

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.

Architecture is exposed to life. If its body is sensitive enough, it can assume a quality that bears witness to past life.

Normally, architects render a service. They implement what other people want. This is not what I do. I like to develop the use of the building together with the client, in a process, so that as we go along we become more intelligent.

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.

If you look at the Earth without architecture, it's sometimes a little bit unpleasant. So there is this basic human need to do shelter in the broadest sense of the word, whether it's a movie theater or a simple log cabin in the mountains. This is the core of architecture: To provide a space for human beings.

Architecture to me is whole. I cannot say I only care about this 25% and the other 75% I let go... it's just I want to work the way I want to work. In my shop, you can order certain things and other things you cannot. They are not available.
