This time around, for the apartment blocking for the animatic I looked up some standard measurements for floor to ceiling height and door height.
Room height should be between 2.4m to 2.75m which I found here:
Height and size regulations for rooms: http://theconstructor.org/building/building-bye-laws/height-size-regulations-for-rooms/5116/
Information on doors: http://www.build.com.au/standard-door-sizes
Habitable room and ceiling height: http://www.abis.com.au/habitable-room-and-legal-ceiling-heights
When I was creating the measurements of the last apartment that I blocked I made the ceilings taller than this but I suppose measurements can change depending on the architectural style, like high Georgian ceilings.
