Several times I have been met by the question about clasroms.

I will dare to say:
NO – Not necessary

In the self help secondary school, first established by Patric v Rensbüreg, the same room(s) were used for sleeping, dining and teaching.
In the given situation anything more is unnecessary luxury and prestige.

In the project I try to propose, the “classes / number of pupiols” will be very small – may be less than 10 pupils.
In this way the “unqualified teacher” will have better contact.
Everything can be done on the veranda of the “family houses”.
