An eight-bedroom house, a semi-detached and an end-of-terrace house are all sold at auction. Martin Roberts and Lucy Alexander meet the developers all keen to make some money on their investments.

Property renovation series. Martin looks around a tired-looking bungalow in County Durham bought by a couple with three labradors and meets a new property developer who is working on a terraced house in Wales, while Lucy follows the progress of a flat in central London.
