ABSTRACT
If you imagine how they built houses in London in the 18th century you will realise that they dug big basements from street through to mews, they then raised the level of street and mews by dumping rubbish from the basement on them. As a result they were often left with clay for making bricks with. Sometimes the house must have risen directly out of the same hole its bricks came from. One day when we have thought up the right handling systems, we might do it again.
