Floor plans are useful to help design furniture layout, wiring systems, and much more. They're also a valuable tool for real estate agents and leasing companies in helping sell or rent out a space.
While you can change your floor plan in the future, remember you can't change the location. With this in mind, don't make the mistake of falling in love with a floor plan and forgetting about the property and surroundings of your home. If you fall in love with the layout of a master bedroom in floor plan, but don't like how it looks out over the street in the model home – chances are your home in your location will have a totally different aesthetic, view and therefore feel different. Remember when choosing a floor plan; ensure the interiors will fit with your location.
