Augmented Reality for BIM objects

I would like to develop an project featuring AR for BIM objects. The idea is to use a similar approach to that of the IKEA Catalog, where the user can set objects - their furniture- in the space where they are standing in. The objects can be manipulated in real time.

Generically-speaking, the goal is to overlay from small BIM objects, to roof/wall solutions to entire buildings in the scene.

I have some experience with Javascript and I'd like to make a webapp by setting a Three.js scene (http://threejs.org/ - the user does not need to download any apps) on top of a camera stream.

Let me know if you have any ideas to make this better! Thanks
