An incredibly private situation, less than a minute’s walk from the open expanses of Blackheath, presents a rare and wonderful opportunity for restoration. This exquisite mid-century modern home was designed in 1964 by the architect Paul Tvrtković for his own family and remains in remarkably original form, like a capsule of time from its conception. It rests atop a south-facing hill on a plot of around an eighth of an acre and extends some 2,300 sq ft inside.
