The stairs in a renovated water-tower residential building in Shanghai. The water tower was transformed into a house in 1980s due to the shortage of houses at that time. Ren Likang and his wife have been living in the place, with a usable area of 39 square meters, for over three decades. The couple renovated their house last year to make it more spacious and bright. But the building has been marked for demolition. (Photo/IC)
