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 top of The Arc — 680–698 m² and a 392 m² terrace above the marina
The Penthouse 4 Bedroom sits on the uppermost of the building’s seven levels: 680–698 m² of interior and a covered terrace of up to 392 m² — a complete outdoor floor with a pergola-shaded lounge and dining area, planting and space for a private pool deck, looking down on the marina inside the curve and out to the open sea. Four bedrooms on this scale give a principal suite with its own glazed bathroom and a kitchen with a long island set apart from the formal dining room.
Two light-branded collections are available: Øria in soft greys and white onyx, Øpal in ivory travertine, oak and linen; both bring 10–25% discounts at Nikki Beach Resort & Spa Muscat. Full-height glazing, a smart-home system and a privacy-planned layout are standard, and owners furnish the penthouse as they choose. Residents have a 24-hour concierge and security, a lounge and pool along the curve, EV parking and marina berths with valet. The 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.
