About this 3D model

needed a scale model of a house so what would be better to make one of your own. This is the house i grew up in and my parents still live there. I looked up the original drawings (which by the way are about than 100 years old) from the house i grew up in, scanned them and used them to sketch the house in CAD. I tried to keep the model simple enough but still keep a certain level of detail. The model is at 1:87 scale (same as some model trains).
