The building boasts of “world-class” facilities for residents who can opt for independent living or assisted-living care.

An advanced “memory care neighbourhood” within the building also offers a “loving environment” for dementia patients.

The Watermark’s carers are known as Nayas – a Sanskrit word meaning “a guide or person of wisdom” – who are tasked with cultivating “a sense of well-being and connection” among residents.

Another is Inspir Carnegie Hill, a purpose-built residence for “modern senior living” that opened last spring in Manhattan’s Upper East Side.

The building aims to offer “urban senior living on a luxury level”, with an interactive programme of events and menus featuring “locally sourced and flavourful superfoods”.

Meanwhile The Landing, which is opening in the suburbs of Washington DC in 2022, will offer residents with discerning palates three “world-class” restaurants, as well as amenities including an outdoor sculpture garden, a 
spa and a state-of-the-art fitness centre.

David Freshwater, the chairman of the company behind The Landing and a number of other senior living communities, said the current crop of seniors have begun to demand more than three meals and basic living needs, as many nursing homes did for the World War Two generation.

“Boomers question things,” he told the New York Times. “They don’t want to be entertained so much as engaged.”
