Plans Show Adjacency
A plan is adjacency made visible. Rooms are nodes, walls mark separations, and doors create traversable connections. The drawing puts the relationships among spaces into a form the team can inspect.
One adjacency appears in two views
Six independent rectangular cells occupy a 3 × 2 scaffold. A graph edge represents a shared side, not a door or traversable path. Each edge stores the actual shared boundary length. The abstract node layout is a different projection of those same seven records.
A bedroom cluster with a shared bath and a kitchen open to the living area illustrates how adjacency shapes the layout. A plan may contain every requested room and still arrange circulation or privacy poorly; tracing connections helps make that problem visible.
Adjacency is one lens on a plan. Dimensions, daylight, structure, accessibility, and services also shape whether the arrangement works.
