The skyscraper is perhaps the most recognisable icon of the modern urban landscape, but what does it really take to sustain human life at such enormous heights? Exploring the interconnected systems that make life liveable in the sky is the task of Kate Ascher's stunningly illustrated The Heights. Ascher examines skyscrapers from around the world to learn how these incredible structures operate. No detail is too small, no difficulty too big to escape Ascher's encyclopaedic eye. Filled with vivid illustrations and anecdotes, The Heights is the ultimate guide to life on high.
