Strategies:
Try to have the short dimension of your rooms be along the window wall.
Smaller apartments will only have one side facing windows
There are only so many corners in a building for multiple sides of windows.
There is only so much perimeter of your buildings, so try to keep any space that doesn’t require natural light to be away from the window.
Try to create a module that is consistent (maybe it is a certain depth) and then the width becomes longer as you add bedrooms.
