I’m stalking the Holy Grail of modernist design. Thurlow House, in the Sydney suburb of Blakehurst, is part of an important collection of early houses by one of Australia’s great architects, Harry Seidler. This untouched gem from 1952 has my mid century heart fluttering. A very sympathetic renovation (the carpet on the stairs must go), fill it full of classic furniture and live your mid century dream. For sale via Modern House.
