The purpose of this technology project was to research and implement sustainable architectural technologies in a design for a new library in Copenhagen. Working with 3 other students as a side project, the final proposal was for a modular system of levels tapering off to the apex covered by a large ETFE structure that paid homage, in form, to its surrounding context. The concept was inspired by MVRDV's Book Mountain project in The Netherlands. As a new form of library, it focuses on smaller spaces and reading and media rooms as opposed to the traditional open library format. It also has a large emphasis on leisure, such that visitor can spend time in "outdoor" areas to read and enjoy views of the city while still being protected from the weather.
