Layer 1 — Residential
Cottage-style housing of four to six children, private and semi-private bedrooms, grouped by age band (within about three years), regulation profile, and personality compatibility — and never by diagnosis, IQ, or ability.
Siblings are never separated. Each cottage keeps the same two or three primary caregivers on a fixed rota, because for a child whose defining wound is that adults leave, the fact that our adults stay is part of the treatment.
Night-support needs shape a cottage’s composition — no more than two children requiring intensive night care share one home — but they never define its identity.
One deliberate exception proves the rule: children with Prader-Willi syndrome live in a purpose-built food-secure cottage, because the evidence is unambiguous that the environment itself is the treatment. That is an architectural protection, not a social separation — they share school, chapel, guilds, and fellowship with everyone.
