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.
The mid-size Sky Terrace — up to 516 m² inside and a 217 m² covered terrace
Sky Terrace Type 2 is the step up from Type 1 in every dimension: 459–516 m² of interior, the widest size spread of any four-bedroom at The Arc, and a covered terrace of up to 217 m² that wraps the glazed facade and takes a full outdoor living and dining set-up with the marina and the Gulf of Oman in view. The kitchen, with a long stone island, opens to the living room, and the bedrooms are planned away from the entertaining space.
The residence is available in Øria (soft greys, white onyx) and Øpal (ivory travertine, oak, linen); both are light-branded, which gives owners 10–25% discounts at Nikki Beach Resort & Spa Muscat below the building. A smart-home system and full-height glazing to the sea and the Hajar mountains are standard; owners furnish as they choose. Services include a 24-hour concierge and security, residents’ lounge and pool, EV parking and marina berths with valet. The exact uncovered terrace area is confirmed per residence; price and handover on request.

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