As a society, we spend 90% of out time indoors and only 10% outdoors. Yet much of the focus for healthy cities is on outdoor space and external environments. Whilst it is important to consider all aspects of a healthy city, at present there is a disproportionately low concern for healthy architecture. The public health paradigm is moving away from a medical model towards an anthropological model; an holistic approach to unite healthy lifestyles and healthy environments. This is more than just the reduction of pollutants or hazardous materials, but towards ‘health plus’ - the design, planning, construction and inhabitation of architecture that facilitates healthy living. Design is used as a research method for integrating public health into architecture.
