A IDR15trn (US$1.3bn, €937m, £768m) project in the business district of Jakarta, Indonesia, – described by developers as a "megasuperblock of buildings" – is to feature a range of leisure and spa facilities.

The 15-acre Ciputra World Jakarta project, owned by the Indonesian property developer, Ciputra Group, will features 15 towers in three separate Ciputra World Jakarta clusters, which are currently under construction.

The first cluster consists of an office tower, a 180-bedroom Raffles Hotel Jakarta and a 11,840 sq ft (1,100sq m) Raffles Spa, with both expected to open in 2017. There will also be retail space, an art museum, a 1,200-seat auditorium, Ascott serviced residences and a tower for apartments.

Construction on the Ciputra World Jakarta 2 began in 2012 and is expected to be complete by 2016. It will feature four towers used for office space, the W Hotel Jakarta – expected to include a spa – The Orchard Condominium and The Residences & Fraser Suites Serviced Apartments.

Ciputra World Jakarta 3 is the next development, expected to provide meeting space, office and apartment towers but it is not yet known when this will be completed.
