Shearing Layers: Time Is The Essence


Time is the essence of a real design problem – Francis Duffy. 

I found this reading extremely useful; it’s simplicity of content and potential implications on future planning, particularly in relation to resource scarcity, embodied energy and sustainable retrofitting, gave a practical design methodology that one can apply immediately to any design project – old or new.

One aspect I found myself questioning was the statement that ‘Site’ was eternal. First of all, I believe this requires a definition of what exactly site includes; is it purely land, is it ecosystems, is it social fabrics, is it town planning zones, property boundaries, waterways etc.? I would argue that regardless of which of these you include, site is never ‘eternal’, at least not in a static sense. Site is ever-changing, however, most often on a time scale which far exceeds that of the building structure and other components discussed in this reading.

Examples of significant site changes include:

Natural: Slow onset flooding, with the potential to turn 'site' into a lake/waterway for months/years. Erosion of sea side 'sites'. Sea level rises in future are also a real threat to long term changes in 'site'. 

Human Made: The Highline in NY showed how new development, improved ammenity and town planning codes can create a significant change in site. When you consider the change in what a designer might initially note in site analysis these 'uneternal' aspects of site can play a huge impact in the type of development proposals clients and designers would consider.
