Hadeel Ibrahim: Chiswick, London

It's good to talk. Or in the case of African telecoms magnate Mo Ibrahim and his 25-year-old daughter, Hadee (pictured), it's even better to spend.

Smashing sales records for Chiswick, west London, Papa bought young Hadeel the home from a minor celebrity for £12.5 million three years ago.

That person had bought the house, which is on Chiswick's most expensive road running along the Thames, for £7m (pictured right). Chiswick Mall is regularly flooded by the Thames and many of the houses have raised front doors and 'sealed' front gardens to ward off the deluges.

After refitting the interior of the 300-year-old house, it's easy to work out that the previous owner made a tidy profit on what is one of the most coveted houses in the capital - although Mo, who has a fortune estimated at £3 billion, is unlikely to upset about that. His foundation gives African leaders who govern their country's effectively a £5 million initial payment and a £200,000 a year stipend.
