The second house is named Ober after a cave in Kresevo. Its ceiling is decorated with stalactites to provide the feeling of being in the cave.
"Ober in history has been the mine from which Kresevo miners had extracted cinnabar and melted it to get gold," said Marija.
Her house's door and window is painted red after the colouring of the cinnabar ore.
The other three houses, which should be completed soon, will also be named after local attractions.
For example Bedem, with towers on its corners, is named after the fortress where Bosnia's last queen, Katarina, had stayed while in Kresevo.
Tourists from across the region and other European countries have already started visiting, Marija said.
