Small massing models like this help give clients a visual idea of square footage and massing. This  model uses three colors that are all the same temperature to represent street, side and grassy areas and a gray for the building. New massing pieces made in white represent the new  square footage and  are made to fit exactly where the existing building ends. Here are three areas of interest,  an entry, building connection and gymnasiums expansion  were new pieces. It’s easy and effective to have many pieces made ahead of time when communicating to clients.
