Flexible Architecture Example...

Alibaba Headquarters by Hassel architects features a  "flexible, open plan workplace that has been designed to encourage informal and creative meetings throughout the complex. Hubs, internal and external streets, bridges, roof terraces and strategically placed destination points contribute to the collaborative nature of the workplace."

The idea of the campus being arranged around a central open space surrounded by a cluster of buildings or ‘neighbourhoods’ is a concept I think could relate in some way to the parliamentary sytem. Maybe instead of one large building (Parliament House), a series of smaller, more flexibe spaces could be arranged over the central core, and changed to suit the needs of parliament at the time.
