The Gensler-designed Sapphire Residences in Colombo, Sri Lanka, will be connected by a sky bridge topped with a swimming pool, and have interiors by Philippe Starck.
US architectural firm Gensler designed the skyscrapers for developer ITC Hotels. The shorter tower will be a 140-metre-tall hotel, while the taller one will reach 224 metres and will be filled with 132 luxury homes.
Between the 19th and 21st floors the parallel towers will be connected by a 54-metre-long sky bridge. A bar and lounge will be located on the lower levels, with sun decks and swimming pools on the upper level.
A helipad will top the taller of the towers for VIP guests and residents to use.
