A popular studio for educational activities: assembling Lego constructors, robotics, school preparation, engineering, etc. At the age of 5, we were approached only by the circle of Young technicians - Lego construction. My son liked it, he runs to classes with joy. Among the disadvantages, I can note poor ventilation in the hall, where the parents are waiting, it is very stuffy, the air is stale. I haven't evaluated the inside of the study rooms yet, but I would recommend that the owners contact specialists in exhaust systems.
