I'm sort of new to scenery design, so I hope someone will be able to help me with such issues! I've attached a 3D rendering of a scene from my production, and in this scene, I've designed 6 - 8 flats (on wheels) to be set around the stage. These flats are about 10m tall and 1.5m wide. Is this dimension absurb? I've got a friend who told me that it's not feasible as the flat will sure topple regardless of the weight of the base. I'm not sure how true it is, so need some advice from you people!
