The OWO Residences by Raffles

Operating

The residences

The 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.
Raffles
The business the brand comes from — hotel, fashion, design, automotive, restaurant, club, or a developer’s own name.
Hotel
How 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.
85
The kinds of home offered — villas, condos, penthouses, lots — and how they break down. Not how many, and not what interest is sold.
studio to five-bedroom residences including two turret residences, with kitchens by Smallbone
The interest a buyer takes: whole ownership, a share of one residence, or a right to use it.
Whole ownership
Whether a hotel shares the site, the building is mixed-use, or it is residences only.
Hotel on site
The published asking range or entry price.
GBP from 4M
When the project was first made public.
No opened page states when the residences were first made public. The building database records the building acquired by the Hinduja Group in 2014, which is a transaction date rather than an announcement.
When its residences were first released for sale.
No opened page states when the residences were first released for sale; the marketing agent's development page lists residences without a release date.
When ground was broken on the site.
No opened page states when construction began on the conversion. The building database names Ardmore as main contractor without a start date.
When the residences were handed over to buyers.
