Laser scanning is also for home projects. It is not just for big, commercial developments. Doing a 3D scan of your patio and backyard, for example, will let you design (to the millimetre) home improvements such as putting a deck, awning and even a play house!
Since it's also on 3D and point cloud, you can have a "walk through" of your design in virtual reality (VR) and make changes until you are happy with your future patio and backyard.
All these are done pre-construction and pre-fabrication, so errors are minimised and you are sure to stay within your budget!
