Speaking of detail:
I've decided thats it's best to get you floor plan done before addong desks, tables, and other furniture.
Go slow, one floor/room at a time.
Align your textures right when you finish a rooms walls, floor, and ceiling. It seems easier then waiting till your map is done to realign your textures.
Off Topic: What's up with these posted pictures? They all come up with an "X" for me, save one. MuzzleFlash's fourth pic is the only one that I can see in this thread.
