Well, here it is – a lavish, sprawling riverfront mansion in Dalkeith that literally defies belief.

From diamante-encrusted cupboard handles in the dressing room to a 10,000 bottle underground cellar, 21-seat private theatre and a marble-floored ballroom with capacity for 400 guests, this manor is akin to a luxury hotel.

High profile agent Willie Porteous is managing the sale, seeking expressions of interest from $50 million.

And if it attracts that price tag, the six-bedroom, 14-bathroom mansion could earn itself the title of one of the most expensive homes in Australia.

Western Australia’s most expensive home is currently a $57.5 million property in Saunders Street, Mosman Park bought by mining magnate Chris Ellison in 2009.

Built over six blocks on 6406sqm, the mansion offers more than 2900sqm of living space over four levels overlooking Perth’s stunning Swan River in a creation that almost certainly “ticks all the boxes”.

Originally designed by renowned Perth architect Geoffrey Summerhayes and updated by Andrew Boughton, the house captures 240-degree river views.

There is a resort-style swimming pool with a 12-seat swim-up pool bar, a sauna, indoor squash court, floodlit tennis court, billiard room, gymnasium and children’s playroom.

In addition, the garage can accommodate 12 cars and there is a boatshed, private mooring and lift inside the home.

There are three kitchens, a walk-in cool room, a separate pizza, teppanyaki and barbecue house and the temperature controlled walk-in wine cellar has its own dining facilities.

Summerhayes, an architect for more than five decades, is known for several impressive works including The Coombe, a clifftop home in Mosman Park, and the Wallace House in Peppermint Grove, which melds Parisian and Tuscan design elements.
