@Alb the problem with going for Rohloff specific frames is there's not many around, off the shelf, and the ones that are available tend to be heavy duty, i.e. expedition type frames. By using something like the Monkeybone and the appropriate axle plate you open your choice of frames hugely. You still need to allow for chain stretch/adjustment though so sliding DOs, an EBB or mess around with magic gear calcs and chainring sizes etc.
