A peek into three decades of Leslie Walford's private Double Bay designs

The Princeton, Double Bay penthouse of the late interior design doyen Leslie Walford has been listed for sale with $4.5 million-plus hopes through Christies International agent Ken Jacobs.

It's been listed by Walford's partner, Colin Davies.

The penthouse  with 279-square-metre garden terracing sits atop the 1939 Art Deco building with northerly views across the harbour to Manly.

The interiors showcase the tastes of Walford, who retired just five years ago after an international career spanning five decades. It was built with polished timber floorboards, high vaulted ceilings, ornate cornices, curved bay windows and french doors.
