This is a house I made in SketchUp I followed the instructions to make the house then we did extra features like the window in the top and the doorknob. After we did our house we colored it I did a light pink tint for the windows and for the color I used was for a section for roofs. People use this program to design things they are gonna make in real life like building a house like this one or a specific model they want with the measurements they want.
