Uncovering a Brisbane property of this extraordinary calibre is a revelation, as its only visible element from the lower street level is a Batman-like tunnel.

Reminiscent of a Hollywood film set, the 50m concrete enclosed tunnel is one of two entrances to this most secretive Ascot site.

The astounding tunnel extends upwards to an underground bunker-like garage capable of accommodating eight to ten cars.

Open your vehicle's door and walk directly into an internal lift which transports you to any level of the residence.

The tunnel, lift system and house is a complex feat of engineering which simply has to be seen to be believed.

Edged into Bartley's Hill and overlooking Queensland's capital city, the home's elevated position is extremely private yet manages to capture a remarkable 180 degree vista of Moreton Bay through to Mt Coot-tha.

A contemporary aesthetic, with clean lines and generous voids, frames a city skyline visible from every room of the 1409sq m total living area.

Bi-folding walls blur the divide between the internal and external zones to extend an already lavish entertaining space centred by a Gaggenau and marble kitchen, with scullery and bar.

A total of seven large bedrooms and bathrooms includes the third floor master retreat with its own terrace.

Secluded from this private sanctuary, on a lower floor, are self-contained sleeping quarters ideally suited to an au pair or guests.

The extensive list of luxuries attached to this property also features a theatre, study, billiard room, wine cellar, enormous storage space, two swimming pools, a gymnasium spanning half a level, a zen room, outdoor kitchen and two laundries.

Imposing scale and vast indulgences aside, this family estate has been created for entertaining in a wonderful and extravagant manner.

Brisbane's Ascot is a well-established community, steeped in tradition with grand historic homes on large parcels of land.

Distance to international and domestic airport terminals is less than 10km, while the CBD is only 15 minutes by car.
