I used to think I wanted a house full of light. Clean, white and light. But after seeing this London townhouse I think I've changed my mind. I want a house that's green - green outside and green inside - a rich, bottle green, a dark, sumptuous green, all the better for pairing wood and gold with. I want bookshelves and bookshelves, comfy chairs, low tables and even more books. Green for plants, for vegetables, for jade and formica, green for the covers of Penguin crime classics. Looks good, doesn't it?
