The problem BUILDO solves

Currently, we have websites like 99acres.com, etc. they offer flats, hotels, buildings listings but they don’t offer any real tour of that building/flat. And if someone wants to see the inside of that building/flat then they must visit that place or they can only see some simple camera clicked pictures which doesn’t give that website visitor much idea about the building/flat. So that’s what our idea is: IMPROVING USER EXPERIENCE i.e.
Users can view building 3d model so that they can experience the whole building exterior, user can view the particular 360 views of any floor of that building, user can view that building model into AR also just by scanning their floor from the mobile AR system will detect the floor and place the 3d model inside it then the user can also interact with the 3d model.

Challenges we ran into

Building 3D models are not easily available on the internet. So for now we just took a sample 3d model from the internet.
