The sanatorium is made up of three main parts.
There is the main hospital building which has a concavely shaped southern front. Behind it and connected over a passage is the service and office building. The third part is the living house of the medical director combined with a private sanatorium for ten patients.
Research let me find out that it was highly unusual at the time to have the senior physician operate a private sanatorium and live on the premises, but the investors finally gave in and even financed the whole thing because Dr. K. had planned to pay for this part of the sanatorium himself, and nobody wanted to going to have to buy it from him when he retired. So they came up with the money and built the small sanatorium.
This is actually a 2-in-1 sanatorium!
Here are a couple of inside shots from the main building.
