The site sits at Tunney’s Pasture, and the proposal is called River’s View. The parti is a single relationship: how public ground meets private ground, and how that meeting can be made to connect the site north to south and east to west at the same time rather than choosing one axis.

The proposal is built as four layers, each drawn on the same plan. The parti sets the relationship, land use assigns it, the parks layer tests whether the public ground actually adds up to something, and circulation is where it all gets checked. A parti that only works on paper falls apart as soon as you draw the routes people would take across it, so the block pattern was redrawn more than once to keep both axes working.

What holds the long central route together is the oval path and the canopy structures along it. A green strip that length is otherwise just a gap between buildings, and people cut across it rather than walk it. The canopies give the route a rhythm and a reason, and the pavilion, the water basin and the community building are placed along it as things to walk toward.
