This image is from Google Maps and depicts Maritime Square on Tsing Yi, the island where my grandmother lives. I chose it because I think it is the embodiment of the new millennium Hong Kong urban development.

The entire development is built by the MTR Corporation, a Government-owned publicly traded company that is primarily known for running the Hong Kong metro system of the same name.

The primary attraction of this development is the eponymous Maritime Square Mall, a large five-storey indoor shopping arcade. It is attached to Tsing Yi Station, a metro station on the overground Tung Chung Line and there is a small bus interchange on the ground floor.

The mall has shops including a grocery store, around a dozen restaurants, a Marks & Spencer, bakeries, clothing retailers, electronics stores, a few banks, and some miscellaneous other stores. Notably NOT in the building is a school, otherwise, you might even be able to spend your whole life without leaving it.

There are several towers extending out of the main mall complex which contain hundreds of units of (unaffordable) housing. I think there is a botanical garden on the roof, too. The entrance to these towers is inside the mall, where there's just a lift lobby where you'd expect a shop to be. The lift lobby is closed to the public; a keycard or code is required to enter.

I think it's a similar concept to a 15-minute city, but more like a 15-minute building.
