I think I got all the details in place to make the houses even more interesting. In the first pic above you see the second framework variation with the door in the middle. And all option layers turned on!
Below you see all the options available independently.

You have alternate windows position, stuff and plants. You can have neither, either or both ... leading to 48 possible combinations. With the 6 color/shade variations and optional dirt layers that gives you thousands of combinations. If I calculated correct more than 100.000 for one framework actually! And we have two :-)
