According to 2PM Architects, "Virtual Reality VR is great for architectural projects. It is not always easy for clients to visualise the design from drawings on paper, but Google Cardboard VR with BIM changes all that." The UK-based firm took a look at what other VR solutions are available on the market for architects, and found that "ArchiCAD BIMx with Google Cardboard VR is the best, and most simple, workflow from BIM to VR architectural walkthroughs. Google Cardboard also has the advantage of being £15 and uses the VR on a smart phone. Other VR headsets such as the Oculus Rift and HTC Vive cost over £500 and so are less accessible."
