If you’re willing to put in the effort, you might be able to make it into more of a Italian villa by raising the roof and making it to some points. However, if you want to leave it as it is, you could make a wonderful kitchen and living room downstairs/workshop downstairs. As for the second story, you could cut out a portion of the room and make a landing pad for some flyers. The rest could be a living space with a bathroom and maybe a few bedrooms. However, the opportunities of the space are endless.
