Elderly retired architect Otto Laird lives a peaceful, if slightly bemused, existence in Switzerland with his second wife, Anika. Once renowned for his radical and controversial designs, he now spends his days communing with nature and writing eccentric (and un-posted) letters to old friends. But Otto's comfortable life is rudely interrupted when he learns that his most significant and revolutionary building, Marlowe House, a 1960s local authority tower block in south London is to be demolished. Otto is outraged . Determined to do everything in his power to save the building, he reluctantly agrees to take part in a television documentary, which will mean returning to London for the first time in 25 years to live for a week in Marlowe House.
