I... admit that's not a house I'd consider attractive, no.
Some of the housing types can be crafted by individuals, others (especially the newer ones) require using an FC company workshop to craft. That said, if the issue is the roof (my issue with it would be the roof, anyway), you
can swap out the roof on that for something like the
Oasis Composite Roof or
Oasis Stone Roof relatively quickly.
In general, once you're into housing, I
highly recommend using FF14Housing to look up the things you want. (For furnishings, the preview mode also lets you pick literally any furnishing in the game and try temporarily placing it to see how it looks.)
