Eye-spy play ground
Keeping an eye on the capital is easy from atop Century House, the former MI6 building on Westminster Bridge Road. The £4m penthouse has 2,500sq m to play in, gadgets everywhere and bespoke furniture. Privalight glass lets you see out, but stops others seeing in. Perfect for a game of I-Spy.
