A genuinely different proposition from Sobha's Dubai projects: Siniya Island is a private natural island off Umm Al Quwain, developed by Sobha in partnership with the Umm Al Quwain government. At roughly 16.1 million sq ft (about 367 acres), it's a large-scale waterfront community built around preserved mangroves and wildlife — the developer's own materials describe gazelles, oryx, flamingos, and rare turtles on site, and the island carries genuine archaeological history as one of the Arabian Gulf's oldest pearl fishing towns. Independent reporting confirms the location and scale; the specific historical claims (an Eastern Christian Monastery and Bishop's Palace once stood here) come from Sobha's own materials and we haven't independently verified them.
The island sits roughly 50 minutes' drive from Dubai and 30 minutes from Sharjah, with a planned boat service to Al Marjan Island — home to the Wynn Al Marjan Island casino resort, due to open in 2027 — reported at around 8-10 minutes. Handover for the development is publicly reported for Q4 2028 — though we've also seen sources citing a range from December 2027 through June 2029 across different sub-projects within the wider master development, which is likely just different phases carrying different dates rather than a contradiction; confirm the specific handover for whichever sub-project you're looking at. A 1.7km bridge is reported to connect the island to the mainland. The wider master development reportedly comprises 14 separate off-plan sub-projects spanning apartments, duplexes, villas, mansions, and resorts, with amenities reported including an 18-hole golf course, a yacht club, an ecological park, a business lounge, and a library lounge. Further distances reported: Al Ittihad Road (E11) 4 minutes, Dreamland Aqua Park 7 minutes, City Mall/Al Salamah 14 minutes, the Umm Al Quwain Museum 27 minutes.

As a real example: a 4-bedroom villa we've seen a direct quotation for (Unit PG-V-154, Type 4AM) has a saleable area of 4,822 sq ft, priced at AED 10,607,498, plus pre-registration fees of AED 424,300 and a AED 1,000 stamping fee.
