Limitless, the property development arm of the Dubai World group of companies, has unveiled plans to build a $350-million health resort on the tropical island of Siberia - part of The World Islands project 14 km off the coast of Dubai, said a report.

The luxury retreat, which is the 10th project for Limitless, will be developed, owned and operated by the firm, The National reported.

The resort will include 53 villas and water homes, of which 23 privately owned villas ranging from 650 to 820 sq m that will be offered for sale by invitation.

"The resort will focus on health and wellness, as every villa will have its own spa treatment room," said a spokesman for Limitless.

Each villa will have a beachfront location or sea frontage with a private jetty, summerhouse and mooring facilities, and will come with its own swimming pool, rooftop garden with outdoor kitchen, landscaped ground-level garden overlooking the sea and an internal lift. The villas will be serviced by the hotel and can be leased back to the resort when they are not being used by their owners, the report said.

The company said the resort would include a 2,000-sq-m spa, an amenity building with speciality restaurants, art galleries, auction rooms, conference facilities and libraries, and luxurious accommodation in 30 villas or water homes. At its heart will be a lagoon with water features and a social clubhouse. There will also be a reception suite on the Dubai mainland, where residents will be ferried to the island by private boat.

Construction of the project will begin towards the end of this year, with completion expected in about two years. The project's design will be showcased at Cityscape Dubai next month., it said.
