Yachtie Matt Allen's Darling Point trophy officially listed

The Darling Point home of retired investment banker and yachtie Matt Allen has officially hit the market, some eight months after it was being shopped around privately.

The Lindsay Avenue mansion cost Allen $32 million in 2013, well down from its $50 million hopes when listed two years earlier.

He bought it from the late industrialist William Tyree, who commissioned architect Bruce Robertston to design the home which took four years to build.

Following his purchase, Allen quickly submitted $722,000 plans to extend the floor plate, reconfigure internal walls and replace the smaller windows with bigger ones to open the home office up to the water views.

Recently renovated, the five bedroom, four bathroom residence wrapped in limestone terraces has a home gym, office, study and wine cellar.

On the waters edge of the near 2,400 sqm parcel is an infinity swimming pool and spa which adjoin the boat house, complete with two jetties.

There's also a self-contained one bedroom guest house in the grounds.

Ray White Double Bay agent Elliott Placks is marketing the property, now in conjunction with Richardson & Wrench agent Michael Dunn. It was reported in March Placks was quietly showing prospective buyers through the home with a $70 million guide whispered.

The home is just one of four homes on the exclusive Lindsay Avenue on the tip of Darling Point.

Retired car dealer Laurie Sutton paid $18 million for his five bedroom home, while Caroline Howard, widow of Stan Howard, the late brother former Prime Minister John Howard, is another owner.

It's been Allen's highest profile neighbour, media tycoon Kerry Stokes, that has been the most publicised over recent years.

Stokes, who is completely rebuilding his Dalkeith mansion, has been seeking to extend Glanworth, which he's owned since paying $9.5 million in 1998.

Allen has protested over the years and submitted a number of objections that the extension would "cause unreasonable loss of views of the Sydney Harbour Bridge."

In August Stokes got approval for the $544,000, Heather Buttrose Associates-designed extension.
