You'll have noticed in the last photo by now that a cottage has been placed near the tunnel.
It is made of polystyrene plates, on which a layer of tile adhesive is spread. Thereafter the walls were finished with a damp sponge.
The door and window frames were cut from balsa wood. I used sandpaper glued on paper for the roof slates.
The rain gutters and downspouts are made of brass tubes. The brackets are made from paper, like the roof lead.
Some painting followed before the cottage was finished.

As you can see, it isn't that difficult to create you own buildings.
Maybe this topic will give you the inspiration to try it yourself.

Here are a few photos about the creating of the cottage:
