Get rid of your stairs and climb your way up
Nowadays, interior design is all about saving as much space as possible and having your house tidy and clean. There are thousands of tricks people use to maximize the space in their tiny rooms. Stairways certainly do not help you achieve that minimalist look. So you can try this instead.
This idea looks great in theory. You save a lot of space, and it looks aesthetically pleasing. But in practice, it can be a mess. Never mind that anyone with disabilities cannot access your second floor, but also imagine that after a tiring day, you will have to climb your way up.
