The term "family penthouse" may seem a contradiction but a bespoke Clerkenwell home proves top-floor luxury isn't just for bachelor bankers and rock stars.
The 2,884sq ft duplex in Britton Street "has the most wonderful combination of fluid and double-height spaces", says David Salvi of estate agent Hurford Salvi Carr.
A circular, open-plan living and entertaining space has 360-degree views, including of St Paul's Cathedral, while the 1,300sq ft roof terrace is bigger than most new three-bedroom flats.
Tycoons with toddlers might fancy buying, but could face competition from Mad Men types. Advertising agency giant Saatchi & Saatchi is moving from the West End to a new HQ next door. Price £4.25 million.
Stylish: the open-plan penthouse has been stylishly designed
