While I am taking pictures for the instructions I started to play around with the combination of the larger house and the L-shaped extensions.
Here are a couple of pics of what I put together!
The title pic is: mirrored L-shape on the short side
Then we have same L-shape on the short side

Next same L-shape on the long side

And finally mirrored L-shape on the long side

In addition to these you could make combinations of the regular large house, small house and last sets lean-to.
Now I need to get back to get the release ready! :-)
