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.
Two floors in one residence — the most compact way into The Arc
The Duplex 2 Bedroom is the smallest typology in The Arc and the only two-bedroom that splits its rooms over two levels: an internal staircase links the living floor with the bedrooms above, and the developer’s render shows a double-height living space behind the full-height glazing of the curved facade. Indicative gross floor area is 163–199 m² depending on the core and the level; no covered terrace is recorded for this type, and uncovered areas are confirmed per residence. The duplex belongs to Øpal, the stone collection: ivory travertine, oak and linen with light Nikki Beach branding.
The Arc is a single curved building of 132 residences on a man-made island at the eastern headland of The Sustainable City – Yiti, the marina inside the curve and the beach beyond, sea on one side and the Hajar mountains on the other. The building is fully serviced — concierge and security around the clock, residents’ lounge, pool and deck, parking with EV charging, berths with valet — and owners furnish as they wish. Price and handover date on request.
