With new technologies, we can easily capture 360 photographs and video footage. These recordings are then taken, modified and placed into a VR application. These applications are lightweight and can thus be ran on cheaper hardware than architectural visualizations or full fledged 3D simulations.
If needed, an online database can be created where photos and videos can be stored so that the collection grows over time. Keep in mind this might add some extra cost, depending on the scale of the project.
