A building is hard to judge. It takes many years to find out whether it works. It's not as simple as asking the people in the office whether they like it.

You don't know what the Chinese expect in the way of beauty. The presentation is just a farce. You come into a room filled with 50 people and they don't talk to you. There's very little interaction.

You'd never think of taking a cab if you had to walk a mile down Chicago's Michigan Avenue. But in a bad city you take a cab just to go around the corner.

For me, though, the fun is over when I get the job.

Most architects say: I want to use this type of glass, even if it's too reflective or doesn't let enough light in. However, the use of a certain type of glass might change the comfort level.

In Europe, architects consider themselves artists. They think they're special when they win a competition.

The American attitude towards efficiency and execution should always underlie architecture.

We want our buildings to work like a machine that will create a pleasurable environment.

America has always imported history.

When I think of some of my earlier work, it really seems a fortunate coincidence that I succeeded.

I've never looked at a suburban building as being a minor building and an urban building as being a major building.

I strive for an architecture from which nothing can be taken away.

In Europe, they're more demanding, the ones that rent the build ings.

A building is hard to judge. It takes many years to find out whether it works. It's not as simple as asking the people in the office whether they like it.

Sometimes I have to accept a job I don't really want. Hardly anybody comes up to you with a commission; it's all competitions these days.

Every building is a prototype. No two are alike.

Higher ceilings allow the use indirect lighting, which is much healthier and reduces glare.

Creativity has more to do with the elimination of the inessential than with inventing something new.

We are creating a unique experience. It's starts with how you see the building from a distance.

A city building, you experience when you walk; a suburban building, you experience when you drive.

Critics are entitled to have an opinion, but how can they judge how comfortable a building is? No critic is smart enough to judge how a building will perform over time.

We prefer synthetic rather than natural materials. Natural products are almost too valuable. Wood is much harder to produce than metal. And metal is recyclable, while wood isn't.

I think the younger generation, the people poised to dominate the workforce, are more socially conscious. They are more demanding in terms of environment and how that environment contributes to their life.

German and English firms operate internationally, while French firms do not. The only place where they all have work is in China. Anybody can sell himself in China!

Transparency is not the same as looking straight through a building: it's not just a physical idea, it's also an intellectual one.

A good engineer thinks in reverse and asks himself about the stylistic consequences of the components and systems he proposes.

It's my goal to make a building as immaterial as possible. Architecture is a very material thing. It takes a lot of resources, so why not eliminate what you don't need as long as you're able to achieve the same result?

When I came to America in the '60s, it was the place to be. I wonder if I'd come here today.

The architecture profession has lost a lot of its integrity, especially in the USA. The general architect here has no scruples, no ambitions.

Chinese buildings are like American buildings, with big footprints. People don't care about daylight or fresh air.

I wanted to improve the suburban office building; to create a great urban space in a suburban environment with all that implies about interaction, collaboration and creativity.

For me, drawing generates thinking and vice versa.

I find if my body feels well and I exercise regularly, I think better, work better and feel better.

I think there will be a 200-story skyscraper someday. However, it will require a developer who will not think in conventional terms and for whom economic restraints won't apply.

IBM has a very solid business image.

Success on one project does not necessarily mean success in the next project. You've got to be prepared in everything you do.

When I work, I work very hard. When I don't work, I have to do something where my endeavor can totally take me off what I do professionally, like sailing. It takes all your attention.

Working is actually a pleasure. It's just very time-consuming. It's a way of life. I find that I can work when I travel and work when I run. There is nothing like, on a rainy day, to work.

A building is hard to judge. It takes many years to find out whether it works. Its not as simple as asking the people in the office whether they like it.

We must support initiatives that provide clear, concrete measures and milestones that our troops need for defeating the insurgency, building up Iraqi security forces, and handing over Iraq to the Iraqi people.

In other words, I have no truck for anyone who goes out and does an eclectic building.

We believe that peace is not just signed papers, but rather a contract between generations for the building of a more promising and less threatening future.

Belief in oneself is one of the most important bricks in building any successful venture.

Living at risk is jumping off the cliff and building your wings on the way down.

When I say artist I mean the man who is building things - creating molding the earth - whether it be the plains of the west - or the iron ore of Penn. It's all a big game of construction - some with a brush - some with a shovel - some choose a pen.

Nature is my manifestation of God. I go to nature every day for inspiration in the day's work. I follow in building the principles which nature has used in its domain.

So I rang up a local building firm, I said 'I want a skip outside my house.' He said 'I'm not stopping you.'

We have a group of friends of the museum who try to raise, if they can, periodically something to help us. Of course, the main thing about a building like this is its upkeep. It needs central heating and it needs central air conditioning.

Rather, it is through conciliation and compromise that we are building a fair Iraq, a just state for all its peoples.
