A handmade craft, this craft is a craft to make a small wooden house which is commonly called a mockup, to make this craft we need the previous equipment such as scissors, cater, or glue.
Other materials, such as wooden cardboard and cork for the grass, use fake grass, usually they are sold in craft shops, now it's probably easy to get, I tried to take pictures of some parts from the front side and back. This is a house on stilts with stairs, on the side.
