Joining rooms (Triplex)

[LoganBarnett]

Maybe this is less prevalent with magnetics - I'm using triplex/clips.

How do you folks join rooms together?

I noticed that doorways and even walls are one-sided with the triplex clips. So if I assemble a room with a door that leads to another room, I haven't been able to figure out how to join those rooms together without some convoluted array of columns, walls, and eventually a doorway that just touches. This makes me think I'm doing something wrong. Maybe the reality of it isn't so bad, but I was curious what others out there are doing to get their rooms joined together nice and snug-like.

Thanks for putting together such an awesome series of tiles!
