On certain projects, on big public projects, people definitely are interested in making them greener, but on smaller projects with tight budgets it can be harder.

When people condemn me for designing iconic buildings in cities and not having an idea what a city is, they haven't done their homework. I started in urban design and city planning. It's just that when I got out of school there wasn't much of a market for that. There still isn't.

I used to read more when I was a kid than I do now. It was all sort of fuel for the fire to teach you how to think and how to make things and it informed the architecture that I was doing. It's better coming in with that history and that kind of knowledge and depth of understanding of humanity that is very important for building buildings - for understanding people and how they should live and how you could make your lives better and stuff like that.

The whole can be greater than the sum of it's parts, that we all have something to put in the pie to make it better, and that the collaborative interaction works.

The fact is I'm an opportunist. I'll take materials around me, materials on my table, and work with them as I'm searching for an idea that works.

For me, every day is a new thing.

People live and work in uninspiring environments, but look inside those rooms. Look at the painted walls and the decorations. People rebel even in the most controlled office environment in which they're not allowed to do anything. You see the little bulletin board in front of a person's desk with their photos, clippings, cartoons and whatever else.
