It may look like your typical suburban home from the front, but inside a Melbourne abode lies a feature like no other.

The four-bedroom, four-bathroom property at 12 Mary Street in Hawthorn, that sold on June 1 for an undisclosed price, boasts an underground billiards room with an incredible glass wall offering a view of the pool.

Not only is there an underwater games room, the home also surprises with its concrete floors and expansive use of glass, and curved entertaining area towards the rear.

In fact, from aerial view you would easily assume that the parcel of land consists of two homes, with its façade resembling a character home and the rear, an industrial marvel.
