It's an interesting twist ... I mean, imagine just a mattress, with but three or four ft. clearence at the highest point, sloping to nothing at the margins of the mattress. Your only access is with a ladder, down to the main roob below - you're sleeping just above that room's ceiling.
If the loft was served by stairs, and had clearance for any manner of furniture, without a doubt it would be a habitable room. As such, the other codes would institute egress requirements.
Then again, where is it written that a home must have a 'bedroom?' Has this designer found a loophole?
