Changing Perspective Between Maps

I'm thinking about how maps are set up, and I wondered if it would be a good or bad idea to change the player character's direction and/or the cardinal directions when transferring them to a new map. I know that having buildings face south is good feng shui, but having every building in the world face south gets old after a while. Is changing things up between maps too confusing for players, or can it work?

As long as you make the entrances to the places obvious, then it should be fine (that's just my opinion though).

And be sure to make it so that the event that transfers them isn't in a bad spot, make it so that they still have to walk into the door space to get in and not in front of it, otherwise that will be frustrating to some players ( like me, if that even makes sense to you). 

I want to do this with so many items too, and enhance the perspectives a little,`+- but that's gonna take forever.

If you put a clear path so that the player knows where the door is, then there is no reason why they can't enter a building from the side or the top. It is better, imo, to put the transfer into a conditional branch "Player is facing [direction]" for the sake of consistency. All the towns in my current project have houses like this. The other thing to remember is to try and turn everything round inside, not just the doorway. This means hunting up sideways cupboards, sinks and fireplaces. I never found a fireplace for the bottom wall, so had to make my own.

Sure. But one of the reasons I might have for changing perspective between maps is so that I don't have to find alternate tiles for areas whose focal point isn't to the north.

Trouble is, that simply changing perspective so that you enter a building from e.g. the left side, but once you are in the building you are at the bottom, looks tacky, imo.  Sideways maps don't have to be complicated.  Here are a couple of simpler ones from my current project.

In the first one I have suggested a sideways fireplace by the shape of the walls and have edited an evented lighting effect.  In the screen shot the light from the fire looks a little high - but that's an effect of the mapshot and in game it's better.

The second one does use a sideways fireplace

The other thing is having cupboards against the bottom wall.  Just take the top of any cupboard and position it on your tile sheet.
