In modern cities, miles of unused flat rooftops await a new function. In Rotterdam alone we have over 18 square kilometers of unused flat roof. That must change, and the rooftops can provide the space to realize the housing challenge, energy transition, climate change and inclusiveness in cities. As a starting point for the realization of this, MVRDV was commissioned by the Municipality of Rotterdam to make the Rooftop Catalogue. The Rotterdamse Dakendagen publishes the book as an addition to all its activities to advocate the use of roofs as a meaningful space for the city.

In Rotterdam alone, there are over 18.5 square kilometers of unused flat rooftops. The initiators of the catalogue believe that this should be addressed. Therefore, MVRDV wrote this book on behalf of the Municipality of Rotterdam and Rotterdamse Dakendagen is publishing the book. This Rooftop Catalogue aims to inspire people, not only in Rotterdam, but all over the world. It shows over a 130 examples of rooftop usage, categorised by types of rooftops, building typologies, urban challenges and UN Sustainable development goals.
