For more than a decade, Hugh Campbell commuted on the London Underground from a mid-sized terraced house in Islington to the Mayfair office of GP Bullhound, the boutique investment bank he helped co-found.

His house and his journey to work are now profoundly different. His house in Alderley Edge, at the heart of what is known as the Golden Triangle of villages just outside Manchester, spans 6,500 square feet, over three times bigger than where he lived in London. Campbell walks his three kids, nine, seven and five, to school every morning, then drives the 13 miles to work in central Manchester.
