The building I'd happily see knocked down is an abandoned shopping centre near the river in the middle of Chengdu, where I live. I work as a primary school teacher and I pass it every morning on my bike, so I've had plenty of time to dislike it.
It was built in the late nineties, when everyone thought shopping centres were the future. It's a grey concrete block, about eight storeys high, with tiny windows and a car park on the roof. For a while it was quite busy, but then newer malls opened with cinemas and restaurants, and the shops slowly closed one by one. It's been completely empty for about six years now.
These days it looks terrible. Half the windows are broken or boarded up, the signs have faded, and weeds are growing out of cracks in the walls. There's a fence around it with warning notices, but teenagers still climb in at night, which worries me as a teacher.
There are a few reasons why I think it should go. First, it's genuinely unsafe. Pieces of the outer wall have fallen off before, and it's right next to a pavement full of children walking to school. Second, it's a waste of a fantastic location. It's on one of the nicest stretches of the river, and that land could become a park or affordable flats, which our city badly needs. And finally, it just drags the whole area down. The cafés and shops nearby struggle because people don't want to sit next to an eyesore. I'm usually in favour of keeping old buildings, but this one has no history worth saving.
