Once boasting WA's most ostentatious and famous house, Rose Porteous' Prix D'Amour, a carved-up parcel of Mosman Park land is set to reclaim the title as Perth's most exclusive address, with the centrepiece a sprawling mansion that could be worth up to $30 million.
The palatial home, being built by low-profile investor John Clinton and his wife Lilian on two combined lots, will almost certainly be one of Perth's priciest properties.
Prix D'Amour was bulldozed in 2006 and subdivided into 10 lots. Four houses are under construction, one has been completed and another two landowners are seeking planning or building approval.
Those with a slice of the subdivision, bordered by Wellington, Owston and Saunders streets, include several investors, a retired stockbroker, builders and property developers. Many are long-time Mosman Park locals.
But there will still be a couple of famous faces in residence - Ms Porteous and her real estate agent husband Willie have kept three of the blocks and plan to build on one of them within the next six months if they can reach a deal with Mosman Park Town Council.
Mr Porteous told _The West Australian _ this week that their mini-Prix D'Amour project had gone back to the drawing board because the proposed house was 1.5m higher than the council's 8.5m restriction.
"The architect who designed it didn't listen to the council," he said. "They designed a house we can't build. We had a nice roof feature and they won't even allow the roof to go on, it has to be a flat deck roof."
Mr Porteous said their house would be nothing like Prix D'Amour. "No, we're over all that," he said.
For a start, the Palladian-style house with a modern twist will only have three bedrooms. But one of the blocks, more than 800sqm, will be dedicated to Ms Porteous' rose garden. "We just want big spaces. We want something that's practical, easy to live in and it's not going to take an army of people to maintain," Mr Porteous said.
Mr Porteous and his wife finished building a new home in Nedlands recently. They spend most of their time in Perth though they also own a house in the swanky Melbourne suburb of Toorak. Mr Porteous said the land at the old Prix D'Amour was too special to sell it all. "The whole area is probably just some of the best land in Perth," he said.
Selling agent Peter Burns, from Mack Hall and Associates, said sales of the blocks, some which had been resold since 2006, ranged from $3.6 million to the most recent deal of $6.5 million.
If the market kept moving up, it wouldn't be long before the superblock mansion would be valued at close to $30 million, making it one of Perth's most expensive homes. Last year, Mr Burns sold another property in Wellington Street for $20 million to a couple who knocked down the existing house and plan to rebuild. He said every house in the Prix D'Amour subdivision, which should be full within the next two years, would be worth at least $10 million.
