高速度和高密度已成了地处亚热地带的南中国城市深圳的代名词。这座沿着珠江口出海口东侧滨海带状规划的超级城市中的人口和建筑密度依然与日俱增，超高层建筑中的居住和工作已成为这座城市的日常。城市里的休闲、甚至教育都被带进高空之中。

High speed and high density have become synonymous with Shenzhen, the southern Chinese city in the sub-tropical coast area. The population and urban density of this hyper-city along the eastern side of the Pearl River Estuary is still booming, even after 40 years of rapid development. Living and working in super high-rises has become the daily life of the city. Leisure and even education have also been brought into the sky.

红岭实验小学及其周边城市的所在地原本是福田区西北部的一座名为安托山的小山。这座小山在城市中广为人知是因为它供给了大量用于城市填海扩张的花岗岩土石方，以至于山体被基本削平，仅剩在小学西侧的一座孤独的小山包。其余场地在采石行动逐步退出后被平整为城市开发用地。红岭实验小学的建设用地约 100 米见方，原规划 24 班小学，后因学位缺口巨大而增容至 36 班。现建筑面积约为原规划的两倍，建筑容积率超过 3.0。加上用地东南角基础对地铁线路的避让、道路退缩以及规范上对日照间距（虽然这在亚热带气候的南方常被质疑，但到目前为止仍是强制性的要求）的规定，使得建筑设计面临诸多空间上的挑战。
