    Hi. I'm in the process of moving into a new house, and the cinema room has a hole in the wall to an adjacent storage space. This hole is 75x84 cm and should be perfect for an IB. The downside is that the hole isn't centered on the front wall, it's off to the right a fair bit (1/3 of the wall...
