When you think about façades you think about buildings (one by one, taken as separate items) ; if you think in terms about bocks, the building façade is in a context, be it planar or not…
The façade is in the context of its plan, but also in that of a corner, or related to others in the same street but on the next block. And it is also in the context of whatever happens on the street, be it cars, cranes, horses, ships, you name it…
The façade is just a face of the reality, as it is often rather mute when it comes to describe how deep the building is, or how it relates to the core of the block.
That’s a cool way to look at a block.
