As already mentioned, Malavilla is a fortified farm building; therefore, it was built according to two key concepts: defense and self-sufficiency. On the ground floor, the fortified house has a stable to house the animals necessary for the food needs of its inhabitants.
It should not be thought that animals such as sheep or cows were permanently locked inside the fortified house: they were taken to pasture to feed and to the nearby Rio Fabiola to drink, but once they returned, they could be sheltered safely, protected by the wooden door locked from the inside with sturdy oak posts.
Furthermore, once the internal staircase was retracted to the upper floor, it ensured that even if someone managed to enter the lower level, they would never be able to reach the living quarters.
On the ground floor, there are some details of great interest that testify to the clarity of Malavilla's construction design. On the opposite side of the entrance, a slit was created to protect the house and provide a little light to the room.
On the sides, there are niches for candles or oil lamps, some of which are made of sandstone slabs forming a sort of mitre arch.
Finally, on the right-hand side, a charcoal drawing was found depicting a soldier in profile wearing a Prussian helmet.
