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.
Three bedrooms and a sky terrace of up to 92 m² — the one 3-bedroom in the stone collection
Among the Øpal types the Sky Terrace 3 Bedroom is the step from two bedrooms to three: 319–350 m² of indicative gross floor area, roughly one and a half times the Signature 2 Bedroom, with a covered sky terrace of up to 92 m² running along the facade. A sky terrace is the open deck of The Arc, as opposed to the planted sky garden of the Sky Garden types; uncovered terrace area is confirmed per residence. The Øpal palette of ivory travertine, oak and linen runs behind full-height glazing with views of the sea or the Hajar mountains. Light Nikki Beach branding brings 10–25% discounts at Nikki Beach Resort & Spa Muscat.
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 resident marina inside its curve and the beach beyond. The building is fully serviced — 24-hour concierge and security, residents’ pool and deck, lounge, parking with EV charging, berths with valet. Price and handover date on request.
