Celebrity fashion stars Brooke and Leith Testoni have listed their stunning Mosman mansion for a cool $8.5million.

According to Realestate.com.au on Thursday, the couple spent four years redesigning the five bedroom home.

The stylish pair, who are a fixture in fashion circles, redesigned their abode to make the most of the natural light.

The Heritage home features three bathrooms, as well as formal and informal living and dining areas. It also has a sizeable parent’s retreat.

The home is split across three levels with the fully restored home still featuring some of its original features including the staircase.

The home also retained original arches as well as timber floors. The glamorous marble kitchen includes a butler’s pantry.

Leith is confounder of fashion label, Zanerobe, while Brooke is a fashion influencer and designer in Sydney’s creative circles.

Brooke said she was ‘proud’ of the renovated home in Sydney’s well-heeled lower north shore region.

‘I am most proud of the open-plan living, dining and kitchen area on the ground floor that has a French country vibe, opens to a deck and is an improvement on the original layout where the kitchen was on the first floor,’ she said.

Brooke and Leith no doubt have special memories in the area.

Speaking to Who What Wear previously, Brooke revealed her engagement to her Italian partner was ‘unexpected’.

‘My husband proposed to me at our home in Mosman,’ she revealed.

‘He didn’t want me to suspect anything out of the ordinary.

‘He cooked me a three-course dinner and set the table with beautiful linen, flowers and candles (just how I like it). He popped the question for the 4th course.’

The happy couple wed in a luxurious ceremony at the Hunter Valley in 2015.
