Let's start how we mean to go on, with a little piece of modern architecture history for £225,000. Balfron Tower was designed by Ernö Goldfinger in 1967, and this two-bedroom flat is right on the top floor, with access to a balcony giving views over Canary Wharf. There's a hundred years on the lease, and the £1,300 service charge includes maintenance, hot water, heating and insurance. Which proves you don't need to be a millionaire to live in real style in London.
