Diamond Developers – the SEE Holding company behind The Sustainable City, from Dubai to Yiti
Diamond Developers is the development company of SEE Holding, the Dubai group whose businesses also include The Sustainable City brand, the waste company Tadweer and City Solar. Its model was proved at The Sustainable City in Dubai Land, the first operating sustainable community in the Middle East, handed over in 2016 on 5 million sq ft: solar roofs, car-free residential clusters, biodomes and farms, all wastewater reused for irrigation and no service charges for owners. The same blueprint now runs in Sharjah and on Yas Island in Abu Dhabi.
In Oman the company develops The Sustainable City – Yiti with OMRAN Group, the national tourism developer, through their joint-venture vehicle, the Sustainable Development and Investment Company: 86 hectares on the bay of Yiti, 30 km from central Muscat, with 300-plus villas, 1,000-plus apartments at The Plaza and the 132 Nikki Beach residences of The Arc, planned to reach net-zero emissions by 2040. Yiti is an Integrated Tourism Complex, so buyers of any nationality take freehold title and can apply for an Omani residence visa; Shari'ah-compliant financing is available through Bank Nizwa.
Six hundred square metres on one level — the largest residence below the penthouse
Sky Terrace Type 3 is where The Arc stops being an apartment and becomes a single-floor house over the marina: 601–602 m² of interior and a covered terrace of up to 278 m². It is the top of the Sky Terrace line — nearly fifty per cent more floor area than Type 2 at its largest — and only the four-bedroom Penthouse above it is bigger. Four bedrooms on this footprint mean a full-size principal suite, generous secondary bedrooms and living and dining zones that can be kept apart.
The type is produced in the Øria collection only: soft greys, white onyx, full-height glazing with the sea in front and the Hajar mountains behind, a smart-home system and a privacy-planned layout; owners furnish as they choose. Light Nikki Beach branding gives 10–25% discounts at Nikki Beach Resort & Spa Muscat, and the building is fully serviced — concierge and security around the clock, residents’ lounge and pool, EV parking, marina berths with valet. Price and handover date on request.

Muscat's new coastal district, 25 minutes from the capital

Yiti’s developments are Integrated Tourism Complexes: owners of any nationality hold freehold title and can apply for an Omani residence visa.
