Siari, a Ritz-Carlton Reserve Residence

The residences

BrandThe name licensed to this project and carried on the building. A brand is not a company: it holds no title, builds nothing and runs nothing.

Ritz-Carlton Reserve

Brand typeThe business the brand comes from — hotel, fashion, design, automotive, restaurant, club, or a developer’s own name.

Hotel

Master planThe larger planned community, resort or named development this project sits inside. A standalone building sits in none.

Nauká

ResidencesHow many separately titled homes this project sells, counting every kind it sells. Where it sells more than one kind, each is named and its own count given.

34

Residence typesThe kinds of home offered — villas, condos, penthouses, lots — and how they break down. Not how many, and not what interest is sold.

4-bedroom residences and 5-bedroom penthouses

SettingWhether a hotel shares the site, the building is mixed-use, or it is residences only.

Who is behind it

DeveloperThe party that promotes the project and carries it through to delivery. May also hold title to part of it — being one does not make it the other.
