Mounted Bookshelf positioning/collision issue

[Jandor]

You can float the bookshelfs in the same way you float troupe stages.

I'm not at home at the minute to take a proper clear picture, but essentially you can rest them on the little ledge that runs along the walls then rotate them flat. This way there is no camera clipping and as a bonus they reach up to the ceiling, I then use half partitions to cover the base.

Best pictures I've got already uploaded.
