1 - 4: Episode 4

John from the country office has a £3.6million Arts and Crafts-style south coast seaside mansion to sell, Polina is listing a new central London penthouse worth £4.5million - so new that it is not even on the market yet - and company owner Guy is in Barbados to view a $40million beachside property where the rich and famous have stayed. Amber is keen to win one of London's most expensive properties, a £75million Knightsbridge home that once belonged to prima ballerina Margot Fonteyn.
