The Brisbane mansion worthy of Batman

Is it any coincidence that Brett Walker, who has the same initials as Bruce Wayne, built a secret tunnel leading to his Ascot mansion reminiscent of the Batcave at Wayne Manor?

“It wasn’t on purpose, that’s not really my go,” Mr Walker laughs. “The tunnel has always been a massive wow factor and it makes my mates laugh, but the whole Batman thing, it’s not really my style.”

Coincidence it may be but there’s no denying the tunnel at 128 Crosby Rd, Ascot, is possibly one of the coolest pieces of residential engineering Brisbane has seen.

Reminiscent of a Hollywood film set, the 50-metre concrete enclosed tunnel, one of two entrances to this secretive Ascot site, extends upwards to an underground bunker-like garage capable of accommodating eight to ten cars.

It was no easy build — Walker took a whopping 30 months to build the house, with 12 months of that spent just on excavation and retaining — and the tunnel, internal lift system and house is a complex feat of engineering which has to be seen to be believed.

The tunnel is the only thing visible from the street, which is why the house itself often takes visitors by surprise, Mr Walker says.

“Apart from the tunnel, it’s the view that always shocks people,” he says. “The view blows them away.”

Edged into Bartley’s Hill and taking in 180-degree views of Brisbane, Mr Walker’s house is set over six incredible levels comprising 1409 square metres of total living area.

With six bedrooms, six bathrooms and multiple lavish entertaining areas, it’s a showcase in contemporary yet very liveable design.

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.

The property is being marketed jointly by Stephen Weber and Tyson Clarke of Queensland Sotheby’s International Realty.

Mr Clarke says imposing scale and vast indulgences aside, the home has been built as a family estate and offers much versatility in this regard.

“Although the home offers the opportunity to entertain in a wonderful and extravagant manner, the sheer size of it is perfect for a family to grow in,” Mr Clarke says.

Mr Weber says the home’s location in Ascot, a well-established community with schools, shops and cafes all close by, makes it “the ideal family home”.
