I don't look at what people do with their homes in terms of money, but the social and personal value of what they're trying to do and achieve.

Every decently-made object, from a house to a lamp post to a bridge, spoon or egg cup, is not just a piece of 'stuff' but a physical embodiment of human energy, testimony to the magical ability of our species to take raw materials and turn them into things of use, value and beauty.

Building your own house is a primal urge, one of those universal genetic drives like the need to provide for your family.

If you said to me, 'Lie down on that concrete floor and fall asleep,' I could do it. I can sleep anywhere at any time of day on any surface.

Life involves other people and it is a compromise.

Building your own home is about desire, fantasy. But it's achievable; anyone can do it.

I cannot look at modern buildings without thinking of historical ones.
