Every time I've flown an aircraft, or visited a steelworks, or watched a panel-beater at work, I've learned something new that can be applied to buildings.
I was born in 1935, and as far back as I can remember, I was sketching designs. My first subject was an aircraft, which I imagined myself piloting.
I love flying; I love aircraft, and you could say I've had a love affair with flight since I was a child. I travel a huge amount. I use airports, and as a pilot, I've flown in and out of airports thousands of times, so really, I have a fairly broad perspective.
The only honourable work my parents knew was blue-collar. But while my father Robert ran a pawnbroker's shop, and my mother was a waitress, I moved into a middle-class world with a level of security they never knew.
In Britain, the idea one could go from blue-collar beginnings to the university was so far out, it was quite unthinkable. I took a variety of jobs to pay for tuition - from ice-cream salesman to night-club bouncer. Whatever earned the most money in the least time.
I hope that any expansion of London will learn from the planning examples of some of its most desirable areas such as Chelsea, Notting Hill, Belgravia and Mayfair. All are characterised by high density and a generosity of green spaces. They are all pedestrian-friendly with shops, entertainment, restaurants and pubs within easy walking distance.

Since Stonehenge, architects have always been at the cutting edge of technology. And you can't separate technology from the humanistic and spiritual content of a building.
We now think it hilarious that medieval streets were used as open sewers. Equally, our descendants will say: 'You won't believe this, but people were once allowed to hurl a couple of tons of dangerous metal around smashing into each other.'
Surveys often show people would prefer a detached house with a lawn and driveway to an apartment. I understand this. It's not my place to presume to tell people where they can live. But perhaps that dream will simply not be possible in the future.
The most amazing lesson in aerodynamics I ever had was the day I climbed a thermal in a glider at the same time as an eagle. I witnessed, close up, effortlessness and lightness combined with strength, precision and determination.
I think cars encapsulate the history of innovation and style - it's the other side of the coin of the car being public enemy No.1.
There's a snobbery at work in architecture. The subject is too often treated as a fine art, delicately wrapped in mumbo-jumbo. In reality, it's an all-embracing discipline taking in science, art, maths, engineering, climate, nature, politics, economics.
Anything that reduces fuel consumption and cuts down on greenhouse gasses is good news.
When the Great Fire of London destroyed most of the medieval city in 1666, Christopher Wren was invited to design a new one. Within days, he had drawn up an elegant grid of broad boulevards leading to majestic squares, but it came to nothing - the existing landowners wanted things as they had been.
I describe the design process as like the tip of the iceberg. What you don't see is the long haul: all the endless auditing and things like that.
A life-threatening illness or two certainly gives you an awareness of your own mortality. It heightens your sense of gratitude for things that previously, if you've not taken them for granted, you perhaps never appreciated how precious they were. That's almost a platitude, but one has to state the obvious.
The Italians have long known what makes a livable town or city.
I would never wear anything with a logo. That I really find difficult. It's a frustration that I'll find a nice shirt or something and it's got 50 prints of the logo on it - why do they do this?
Joseph Bazalgette created a sewer system which he originally sized for London's needs of the time - he then doubled it to anticipate the future beyond. These are the qualities that I admire.
