The skyscraper is perhaps the most recognisable icon of the modern urban landscape. Providing offices, homes, restaurants and shopping to thousands of inhabitants, modern skyscrapers function as small cities. 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. Ascher's work is a triumphant ode to modern civilisation.
