Gift project: a potential site?

Plan diagrams l-r: building heights, current routes, main circulation through (retaining wall in yellow)

A typical example of city meeting landscape, Hongjie is not dissimilar to many neighbourhoods in Seoul. As mentioned in the post when I first visited area, as one emerges from the tube station to street level, a bustling shopping street is revealed with mountains lurking on the horizon behind.

I am interested primarily in the long retaining wall which now acts as a barrier between neighbourhoods just off the main street. Currently, retaining walls guide us around the city but are there alternative ways of moving around them? This returns to the idea of ‘one-sidedness’. At Hongjie the retaining wall divides an older low/mid-rise residential area from a new Apatu development which cuts off the mountain from the city.

How is the wall traversed? How have circulation routes changed since its construction? How does city meet landscape?
