Australia's best beach house?

Arguably Australia's best and most expensive beach house goes on the market next month, as owners Scott and Rachel Perrin make the move from beach front to the countryside.

It is likely to set a new record for Queensland residential property, with almost twice the land and twice the house size of another home located on the same street at 1 Albatross Avenue, spanning 1,395sqm which sold for $18m during the GFC.

Situated at 45-51 Albatross Avenue in Mermaid Beach and known as "Tidemark", this 30-plus room home with separate caretaker residence is coming onto the market for the first time since its construction.

“Everyone walking the Surfers to Mermaid Beach stretch is left with an indelible impression of the property with its vast beach frontage and elegant symmetry,” said selling agent Michael Willems.

“It's a property that is understated somewhat, but once you walk through the front gate it simply overdelivers.”

At almost double the size of the second largest beach front holding in either Hedges Avenue or Albatross Avenue it is the only property that has the feeling of an estate, he said.

Just 20mins from the Gold Coast airport, Tidemark has six ensuite bedrooms - the main has a steam room and sauna, two kitchens plus teppanyaki pavilion, fully retractable glass and copper roof, underground basement for 11 cars and separate office accommodation for up to the six staff.

Dan White of White Partners who is partnering in the marketing of the property said Tidemark sets a new benchmark for Australian beach front property.

"Tidemark is a one off. An amalgamation of land unlikely ever to be replicated and built to the very highest of disciplines."

The home is for sale by tender, which will close on 26 May 2015 at 4pm.

Tidemark sits on 2,833sqm and was originally three separate land parcels.
