In Portal, the pavilion's form sought to echo the geometries of both sacred architecture and the natural world. It was considered to be a cross between a cathedral and a piece of coral. An architectural fragment that carried the suggestion of vault, chamber, arch and façade. These subtexts were superimposed with the idea of the structure as a public meeting place.

In this context, the structure was designed to act simultaneously as sculpture, shelter and amphitheatre. A point of destination that responded to the passage of the sun through the day and which would be atmospherically illuminated at night.
