4. Mass treatment
Modern commercial developments tend to have larger massings and volumes than buildings from historic periods. However, it is possible to manipulate the massing of new large buildings to achieve designs that sit comfortably within their historic settings. For example, façade treatments can make a large volume look slimmer, shorter or smaller than it actually is. A good way to do this is splitting façades vertically and working with rhythms.
Cities, streets and façades have a natural rhythm given by the repetition of their parts and their position in space. For example, equal windows with equal separation will have a monotone rhythm; but if the central windows are different in size these can act as an accent. Façades have a vertical and a horizontal rhythm. If the top floors have smaller windows than the lower floors, a variation is created in the vertical rhythm of the building.
Design Criteria
4.1 The rhythm of the surrounding environment has informed the façade proposals.
4.2 The proposed façades help make the mass treatment legible by adding hierarchical variation.
4.3 The proposed façades respond to their immediate environment in scale, form and rhythm. This means each aspect of the building is treated according to its setting.
4.4 Bottom, middle and top floors will be differentiated following the trend of the setting.
