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 largest Signature plan — four bedrooms with full Nikki Beach branding available
At 360–407 m² indicative gross floor area the Signature 4 Bedroom is the largest Signature plan: four bedrooms, a living room and a separate dining area along full-height glazing, a covered terrace of up to 19 m², uncovered area confirmed per residence. The renders for this type — living room, dining room and master bedroom — show the Ønda version, the marina-facing water collection and the only fully Nikki Beach-branded part of The Arc: free spa facilities, valet, kids club, outdoor fitness and yoga at the resort, 50% off the gym and 20% off food, drink and treatments. The same plan comes in Øria, the air collection: soft greys, white onyx, light branding with 10–25% discounts.
The Arc is one curved building of 132 residences on a man-made island at the eastern headland of The Sustainable City – Yiti, sea on one side and the Hajar mountains on the other, fully serviced with 24-hour concierge and security, residents’ pool, lounge, EV parking and berths with valet.
