Designing for legacy

Well, I think the purpose of today is that we've got a lot of architects and designers working on individual projects across the Park. Very few of them have a chance ever to see the whole.

You can see the superstructure really starting to come out of the ground.

What we've tried to do is design a Park with spaces in between the buildings that are as important as the buildings themselves, so you don't end up with a load of trophy buildings in lots of empty space.

It's a great sculptural form, fantastic relationship with the landscape, I think it will become a place that people come to see, just like they used to come to see the Crystal Palace if you like, on a much smaller scale but it's fantastic.

This is the thing that I'm most impressed by. Not because it's just impressive, but because particularly after Beijing it's actually so simple. That for me is what some of the best architecture is about.

The whole project is an amazing celebration of British engineering as well as British architecture. Particularly the Stadium, particularly the Aquatics Centre and particularly the Velodrome.

We've got the interesting challenge we've had right through with the Olympic Park, which is how do you build something which is going to work for the next 50 years, but which is also a spectacular venue at Games time.

The advantage of getting them to get at these kind of forums is really about bringing up their ideas and exchanging ideas so that they take that into the next stage of the design work that we will be following through with.
