The Sustainable City - Yiti, Muscat
The CollectionsThe Arc is a single curve on the edge of the region's first net zero city, standing on an island made for it. One hundred and thirty two fully serviced residences, drawn for a coastline that has to outlast us.
The building is a single arc, set on an island made for it. The curve is not decoration. It is what gives every residence its own angle on the water.
Øria, for air. Ønda, for the wave. Øpal, for the stone that carries water inside it. Three collections drawn for three ways of living, all three carrying Nikki Beach branded ownership privileges.
Ø: O for Oman, struck through for net zero. In Danish it is also the word for island
Air. Soft greys, white onyx and rare stone, and the daylight that moves across them through the day.
The wave. The only fully branded Nikki Beach collection at The Arc, turned toward the marina and the light coming off it.
Stone that holds water. Ivory travertine, oak and linen, and the widest range of homes at The Arc.












From a 163 sqm duplex to a 698 sqm penthouse with a 392 sqm terrace. Fourteen typologies across one hundred and thirty two residences. Every plan is drawn for its own position on the curve, so no two look out on quite the same thing.
The building is one arc, divided into three. Øria takes the first three cores, Ønda the middle three, Øpal the last three.
The arc opens into elevation. Every residence in the building, on its own level, drawn from the approved layouts.
One colour for each. Choose a type to see where it sits and what it looks like.

Every residence at The Arc is fully serviced. The building carries the work so that the home does not.
The city makes up to all of its own power, returns its water to the landscape, and grows food a walk from the door. The Arc is the part of it that meets the water first.
Ownership at The Arc includes everything around it. All of this sits inside The Sustainable City - Yiti, minutes from the door.
Every residence at The Arc carries Nikki Beach branded ownership privileges. Ønda is fully branded. Øria and Øpal carry the light tier. Both are included as standard with ownership.

As per Exhibit D of the Branded Residences Services and License Agreement. Discounts apply to published or best available rates. Subject to terms and conditions, which prevail in the event of any discrepancy.
Most branded residences ask you to live by the operator's rules. The Arc does not. You own your residence outright, you furnish it as you choose, and there is no hotel running through the building for your service charge to carry. The brand, the service and the privileges are yours. The constraints are not.
Ownership, title and service terms are set out in the Sales and Purchase Agreement.
Visit the Sales Centre or arrange a virtual appointment. You can also walk the residences yourself, in full, at virtual.thearc.om.
Areas are taken from the approved unit layout drawings and are indicative. Uncovered terrace and sky garden area is additional and is confirmed per residence. Final specifications are subject to the Sales and Purchase Agreement.
