Largely made-up of reclaimed land, it is being marketed as a "exclusive oceanfront residential community" and the "only true seafront residential property" in Singapore. The master developer of the site is Sentosa Cove Pte Ltd, a subsidiary of Sentosa Development Corporation. The latter purchased the site from the Singapore Land Authority for a sum of about S$800 million.
