LONDON: Dubai’s property developer Nakheel has called for ground preparation proposals for PALM360, a two-tower luxury hotel and residential project that is set to be the tallest building on the Palm Jumeirah. The 260-meter development will include Raffles The Palm Dubai Hotel and Raffles Residences PALM360, and is due to be completed in 2021, according to a statement from Nakheel. It will feature a sky pool, said to be the world’s largest, which will connect the two towers. The hotel will have 125 rooms, and there will be 331 Raffles-branded residences on offer. There are 16 penthouses planned which will come with their own infinity pool, gym, home theater and 360-degree view of Dubai. A tender for the construction of the development is to be released later this year. Nakheel has been behind many of Dubai’s landmark developments, including the Palm Jumeirah itself and The World project, which features 300 man-made islands just off the coast of Dubai, shaped to represent the continents. The developer works across retail, hospitality and residential projects in Dubai. It has around 25,000 residential units under construction or in the pipeline, according a company statement.
