W Hotels will debut in Melbourne with a new 294-room property set to open in 2020.

The new development will be located at 447 Collins Street.

Part of the AUD$1 billion mixed-use luxury development Collins Arch, W Melbourne will be the second W Hotel coming to Australia, following W Brisbane which is scheduled to open its doors in 2018.

With 294 rooms, including 40 suites and an Extreme Wow Suite, W Melbourne will be designed by SHoP Architects from New York, global design practice Woods Bagot and interior design specialists Hachem.

The hotel will also feature a bar and restaurant, a spa, workout facilities, and an indoor heated swimming pool.

Marriott International says W Hotels is on track to reach 75 hotels by 2020.
