Thank you, @TDahl !
To answer your question, I’ll make a presentation of how I worked for doing that model, but because I use Google Translate to write in english, I will use more pictures for examples and fewer words. I hope it’s ok.
I drew the contour of the base of the house on a sheet of paper. I used small pebbles for the base, which I glued together with adhesive.
For the beams I used balsa wood, and for the floor I used some wooden slats. The “beaten earth” of the porch (prispa), I created it using gypsum/plaster and than painted it.
The walls were made of chopsticks for skewers, glued at the corners with wood glue. After that, I put on them with gauze, and then dressed everything with gypsum.
For both, the wood in the corners and the wood used for beams, doors or windows, to give them the old patina, I used a soldering gun, or matches, and two substance: Patina Varnish and Picture Cracking Varnish.
The roof structure is made of the same wood, and the shingle also made of balsa wood.
I used the same materials and the same technique for making the outside kitchen, fountain and fence.
Have a nice day!
