Classroom Structure Robert Davis 2014-08-08T12:39:51+00:00. Building a sturdy structure, such as a house, requires careful consideration of many factors. First there is the foundation which will support the weight of the house. The walls and bearing wall will support the roof and defend against winds, violent rains, or most things Mother Nature throws against it.

The floor must be flat.The furniture will include moveable chairs and tables. For large classrooms, a tiered floor is the norm.he average screen height is 8 ft for a flat floor classroom.
