Additions are optional add-ons that correspond to a specific master plan that a buyer has the option to choose from for their new home. For example, adding an extra bedroom, media room, garage, bathroom, etc. to the approved floor plan. Not all plans will have approved additions, however, if they do the XO will affect the approved square footage ranges as it applies to the plan for the particular addition, and pricing.
When an extra bedroom, bathroom, or garage space is included as addition, the maximum value for the range of that floor plan will increase as well. For example, if the plan starts with 3 bedrooms, and an Addition for an extra bedroom is added to that plan the maximum bedroom amount will be increased to 4 bedrooms.
