The Arc – Duplex 3 Bedroom in The Sustainable City – Yiti, Muscat
About the Ønda three-bedroom duplex at The Arc
The Arc – Duplex 3 Bedroom is a two-level residence of 410–413 m² with three bedrooms in The Arc, the Nikki Beach-branded building of The Sustainable City – Yiti in Muscat. It belongs exclusively to the Ønda collection — the marina-facing, fully Nikki Beach-branded part of the building — so its owner receives the complete resort privilege package rather than the light-branding discounts. Sold by the developer; price on request.

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 only duplex in Ønda — full Nikki Beach branding on two floors over the marina
The Duplex 3 Bedroom is the two-level residence of the Ønda collection: 410–413 m² split across a lower living floor and an upper bedroom floor, joined by an open staircase around a planted, lit void. Ønda is the only fully Nikki Beach-branded collection at The Arc and sits on the marina side of the curve, so the glazing on both levels looks over the berths and the water, with the Hajar mountains at the back.
Full branding brings the widest set of privileges at Nikki Beach Resort & Spa Muscat: free use of the spa facilities, valet, kids club, outdoor fitness and group yoga, 50% off the gym and 20% off dining and spa treatments. The residence is delivered with a smart-home system and privacy-planned layout; owners furnish it as they choose. The building is fully serviced with 24-hour concierge and security, a residents’ lounge and pool, EV parking and marina berths with valet. No covered terrace is recorded for this type; 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.
