This week on The Real Estate Diplomat, we are joined by Catherine Tinker of Chicago based Columbian Model and Exhibit Works. The company builds scale models of buildings, mainly for the real estate development market. They have created many of the scale models of buildings that have been built within the last 30 years in Chicago and many throughout the United States. In this episode, Cathy shares her journey, from starting as a lawyer for the space industry dealing with the Space Shuttle Challenger accident, to creating scaled models of buildings. We discuss why physical representations are an important part of selling the invisible, in addition to digital representations. We also discuss her scale model of the Obama Presidential Library being discussed by former President Barack Obama on 60 Minutes.
