Housing can be split into two tiers: the 'support,' a permanent structure (foundations, shared infrastructure, bearing frame) held in common, and 'detachable units,' the interior fittings and dividers each dweller controls and can change. This separation assigns the collective what must be stable and the individual what should remain changeable.
Centrally planned mass housing treats dwellings as finished products delivered to passive occupants, which removes the act of shaping one's own dwelling. Because the dweller no longer decides or alters anything, the natural relationship between people and their living space is broken rather than merely constrained.
A dwelling is better understood as the ongoing activity of inhabiting and adapting space than as a fixed physical object handed over complete. Viewing it this way makes the capacity to intervene, not the finished quality of the unit, the measure of good housing.
Allocate each design decision to the level that matches its lifespan and shared scope: slow-changing, collectively used elements belong to the support, while fast-changing, personal elements belong to the individual. Matching decision authority to rate of change lets the stable and the variable coexist without one blocking the other.
A healthy settlement behaves like an organic process in which countless individual acts of building and altering continually reshape the whole over time. The town is produced by many hands acting at different levels, not imposed as a single finished plan.
The monotony of mass housing stems not from any aesthetic failure of designers but from the structural removal of the dweller's decisions. Restoring variety therefore requires returning control to inhabitants rather than imposing designed diversity from above.
