This is a bedroom above a connected garage in a lake house. I'd like to put up shiplap or beadboard to cozy it up, but not sure which walls to do. I'm thinking of doing all of the slanted walls and the ceiling (and maybe office nook?) but worried it may look to distracting giving the number of walls/angles. What walls would you do and with what pattern (horizontal vs vertical)? Any preference of shiplap vs beadboard? Two twin beds will soon frame the large window (instead of the bed currently in the pic). 2 photos on bottom are a couple inspiration pics. Thanks in advance for the advice!
