Preface – Manifesto 

Melbourne is known for its considerable range of different weathers during a single day,  which is why it is locally known as the the “four seasons city”.

The project is a summer pavilion located in Grollo Equiset Garden at the National Gallery of Victoria. The pavilion is a gathering space that plays with the sunlight and shadows through a series of perforations created by hyperboloids oriented at different positions, scales and angles driven by environmental data. Thus, the pavilion is an experience for the visitors to live the space in a range of scenarios throughout a day.
