I'm not here to say I don't eat vegetables - I do, a lot of them - but, from a soil perspective, they're actually more costly than a cow grazing on grass.

Vegetables deplete soil. They're extractive. If soil has a bank account, vegetables make the largest withdrawals.

It's a fallen world. We eat and sacrifice in the process.

You can eat a lot more vegetables than you can cotton candy. Bring on the veggies. Stay away from the fluffy carbs.

Conventional agriculture has never succeeded in feeding the world, and it's never produced anything good to eat. For the future, we need to look toward alternatives.

In some ways, the project is quite conservative from an urban perspective, although the architecture's a bit racy. London is basically made of houses. Seventy percent of buildings in London are houses. Houses are what create the public space in the city - streets, squares etc. So when I started, I thought: We're not designing a housing scheme, we're designing a piece of the city, and that should be the starting point for many housing schemes.
