This project was done by Oneiros (startup company based in Milan) in collaboration with Unity. It had the aim to show the potential of their new HD Render Pipeline (HDRP) in AEC industry through the creation of a virtual walkthrough of the newly opened London office, designed and built by M Moser Associates. (Check out the real life building here)
It is possible to move freely between the various rooms using the mouse and keyboard or a gamepad. The users are able to interact with some aspects, such as switch between a day/night mode, changing floor materials, turning TVs and lamps on/off, and accessing BIM information.

Light turn on/off and BIM infographics
It is important not to forget that one advantage of using Unity in architectural visualization is that you can get different types of output from the same scene. For example, it is possible to make a video in cinematic mode, as well as in virtual reality mode.
