These two simple high rise buildings were made in blender and it comes with basic materials so you can easily add your preferred textures easily. The model can be used for different things, from simple renderings in blender to complex AAA game. The second house (destroyed house) comes with separated mesh so you can add easily simulate an explosion with it. When used for games, you dont need to add any script to the building to make it scatter, just add some sort of collider to each mesh of the model and a rigid body and watch the most realistic explosion ever.
