Floor plans should include key dimensions and levels as well as annotations to indicate materials, fittings, appliances and any other relevant information useful to a buyer or renter. They can be drawn for a whole building or even just a singular room, but the more detailed they are the more instructive is the plan for the end user.
All walls should be clearly demarcated as well as rooms, their size and their usage, and any windows, stairs, lifts, doors and even ceiling fixtures, if any.
Everything about the floor plan should make it easy for a person to decide if they deem the property suitable for their purposes and if they wish to view it.
