Influential Australian architect Stan Symonds sure has a way with design. One of his architectural works is on sale in Sydney and it is the whole package.

The house has been getting giggles from interested buyers due to the phallic shape of the floor plan. The beautiful curvature of the penis-shaped home has remained the same since it was built in 1958.

The property is described as a "unique and very private, architecturally designed residence set on 1,204 square meters (3,950 square feet) with a tranquil bushland backdrop." Yet, it isn't until you see the layout that you realise just how "unique" it is.

Agent Phil Vanstone from LJ Hooker Mona Vale is selling the modernist property, called Sherwin House, and says he believes it was an intentional decision by Symonds. "He is a very bright fellow, so I imagine he probably does know it is shaped as the way it is," Vanstone told Mashable. "[The current owners] think it is a bit tongue in cheek."

To grab the Church Point property you will need to cough up in excess of $1.1 million, be a fan of modernist architecture and have a sense of humour.

"I had one couple come through and the husband was having a bit of a chuckle about it, and his wife was telling him to stop being a child," Vanstone said.

Vanstone laughed when questioned about the main selling point of the property, before saying the design really is the main feature of the home but not for the reasons it would appear.

"To have a house that the kitchen has a view of the swimming pool and for the outdoor and indoor entertaining areas to flow off the kitchen is a premium thing to have in a property," Vanstone said. "This house has been designed with that in mind.

"It is a very liveable floor plan, although a bit odd, and the fact it has all the original carpentry shows it is a very liveable design, as people haven't gone messing with it," he added.
