The five-bedroom and seven-bathroom property in West Pennant Hills has an open-plan layout spread over three floors and is accessible via a lift.

It resembles the lobby area of the fictional CEO Logan Roy's New York flat in the popular streaming series Inheritance.

It has a range of luxurious features including stone tile floors and six-metre high ceilings in the living areas.

From a gourmet kitchen to a theatre room and even basement parking for 10 cars, the sellers spared no expense in building the property.

Sotheby's brokers Reuben Kee and Sarah Khazma are managing the listing of the luxury-built mansion, which is similar to another hidden gem listed at Bella Vista Waters last month.

The six-bedroom property in south-west Sydney is reminiscent of a French provincial home and is built for entertaining and family life.

Mr Kee said the properties in West Pennant Hills and Bella Vista Waters had received interest from international buyers from around the world.

"These properties are such unique buildings that we have received enquiries from overseas and out-of-state buyers.

"This is a seamlessly integrated three-storey home which has been designed and built to incorporate an earthy finish."

"Both properties are located in prestigious areas and offer exceptional features that make them truly unique."

There is no published price guide for the property.

A review of comparable homes in the area suggests that the property could reach one of the highest prices ever paid in the area.

According to PropTrack, West Penn Hills' suburban performance has increased by 149.2% over the last decade.

Buyers of the property can enjoy a range of outdoor lifestyle features including an open wood fireplace, air conditioning, electric blinds, a barbecue area with built-in speakers, a wood-fired pizza oven and a barbecue gas tray.

Security is also a feature of the mansion, with a full security alarm system and CCTV with infra-red monitoring throughout the property.

"The property at West Penn Hills is a modern masterpiece that blends quality and sophistication with well-designed features that offer a level of functionality that is second to none."

"Both it and the Bella Vista property are available by appointment and by invitation."
