Paying $3.99 for the pro give you nothing extra I can find except it wont delete your project. There are no wood doors. Glass only. There is no way to ad a 2nd floor There is no way to ad a loft. There is no way to do exterior ground/deck There is no wall height choice There is no interior wall material There is no way to raise or lower the floor a step. There is no wall material to choose from. Brick wood etc. Its a kids toy at best. How do I get a refund??? All this app does is allow you to decorate a room with furniture you will never own.
