There are a few basic steps to creating a floor plan:
Choose an area. Determine the area to be drawn. If the building already exists, decide how much (a room, a floor, or the entire building) of it to draw. If the building does not yet exist, brainstorm designs based on the size and shape of the location on which to build.
Take measurements. If the building exists, measure the walls, doors, and pertinent furniture so that the floor plan will be accurate. If the layout is being created for an entirely new area, be sure that the total area will fit where it is to be built. It is advisable to examine buildings built in similar areas to use as an estimate for this floor plan. Learn more about how to measure and draw your floor plan to scale.
Draw walls. Add walls for each room of the building, taking care to draw them to scale.
Add architectural features. Begin adding features to the space by including the unchangeable things, like the doors and windows, as well as the refrigerator, dishwasher, dryer, and other important appliances that must be placed in a specific location.
Add furniture. Add furniture if the floor plan calls for it.
