Four shapes, recognisable on sight.

• The Country Estate A grand house with grounds. Often Georgian or Victorian. Often forty minutes from a city. Communal dining. Walks. A library. Twelve-step or integrative model. Higher cost. The aesthetic does some of the work; for some people that aesthetic is exactly the thing, and for others it is a distraction from the thing. Bedrooms range from comfortable to small. Wi-fi is often controlled or absent. The reader walks in expecting a hotel. The reader walks out understanding it was not.
• The City Clinic A converted townhouse or wing of a private hospital. Inside a city. Smaller cohort. Same programme, different feel. More clinical, less pastoral. Easier for family visits. Less sense of separation from the outside world, which is sometimes useful and sometimes not. The reader walks in thinking proximity to the city will help. Whether it does is the question the four weeks answers.
• The Medicalised Unit A psychiatric hospital wing or NHS-adjacent inpatient unit. More staff. More monitoring. More medical, less programme. Often appropriate for complex presentations, dual-diagnosis, or higher-risk detoxes. Less group time. More one-to-one. The reader walks in expecting a clinic. It is. It is also a hospital, and behaves like one. This shape also covers most NHS Tier 4 / charity-funded residential placements — the route a reader without insurance will most often arrive on — and many regional substance-misuse services. The funding is different. The interior is not, very.
• The Boutique Smaller cohort, often four to eight patients, sometimes one-to-one. High cost. Bespoke programme. Very individual. Excellent for the right person; the right person is not everyone. The risk is that the cohort dynamic that does much of the work in a larger group is simply missing, and the bespoke attention does not replace it. The reader walks in expecting privacy. They get it. They also get fewer of the meal-table moments that change people in a bigger room.

These are not categories with hard edges. Many real clinics are hybrids. The point of describing the shapes is to give a reader who has only seen brochures a way to ask the right questions. Is this an estate or a clinic? What is the cohort size? What is the model? How much is one-to-one and how much is group? How separated from the outside world will I be? The SI (super intelligence) guide will go deeper. The procurement detail — cost, regulator, contract, refunds, who owns the company — is a separate enquiry, and it is not answered on this site.
