$10million James Bond mansion in Hawthorn, Melbourne boasts underwater games room and unique design

From the outside, passers-by would never guess that a quaint single-story home with leafy native gardens hides a modern mansion with a James Bond-esque garage and underwater playroom.

The Grade II listed cottage, with its contemporary extension, is located in the leafy suburb of Hawthorn in central Melbourne, just east of the city centre.

At the front, the family home exudes historic charm with original windows and a classic facade, while the rear is a sleek and sophisticated architectural space that fuses indoors with outdoors.

In the basement is a teen retreat with a full-sized billiards table, TV area, darts board and foosball table – but its most striking feature is the floor-to-ceiling window that overlooks a swimming pool.

Also in the underground level is a five car garage with a James Bond style car turntable to easily maneuver any vehicle out of the driveway.

A dividing wall with an integrated bookcase stops briefly to merge the den and casual living room, and a feathered concrete ledge runs between the rooms.

The home’s historic charm is not lost in its modern design, as original wood sash windows, a mottled glass front door, and rich hardwood floors remain intact.

On the other side of the living room is an intriguing circular wall of glass that runs all the way through the house past the stairs and kitchen to the family room.
