With dash of Vivienne Westwood wallpaper, designer Tina De Salis lists Castlecrag mid-century home as past meets present

Interior designer Tina De Salis has listed the Castlecrag home that she's modernised since she purchased it for $2.59 million in 2009.

The 1960s home has five bedrooms. It sits on a 696-square-metre mostly level block on The Redoubt.

Mark O'Brien of Richardson & Wrench Castlecrag & Northbridge has the listing for September 12 auction with $3 million-plus hopes.

Property Observer has contrasting then (below left) and now (below right) images from the two sales campaigns.

Edward de Salis and Tina de Salis, who is a partner in Tina & Louise Interiors, has just had it photographed for Belle and Vogue Interiors, no doubt attracted by the decorative wallpapers by Vivienne Westwood for Cole & Son.

It was designed and built by architect Ervin Mahrer in 1966 with its solid brick and reinforced concrete, extensive use of Californian redwood, mudgee slate stone walls, and polished brushbox flooring.

Mahrer sold in 2009  through Mark O'Brien, but went back at the weekend inspection to take a quiet look at his former home of 43 years.

Positioned highside in one of the Crag's sought-after cul-de-sac's, it has a  north to rear aspect.

Orhan Ayyüce, the senior editor for Archinect, recently noted Ervin Mahrer was a Hungarian immigrant and a great modernist architect in Sydney.

"He is still active and designing buildings in his 80s," Ayyüce blogged.

The property at 2 to 4 Notts Avenue, Bondi Beach, is an Ervin Mahrer design.

Ayyüce described its as a beautiful apartment building overlooking Bondi Beach.

"Great capture of the sculptural aspect of the building as it beautifully takes the curve of the street and the slope," he observed.

Title Tattle recalls the 30-unit block – most recently updated by Stanic Harding – was built by Bill Shipton in 1981, with the venture capital provided by tycoon Kerry Packer.
