As part of an interior design project for a young couple, Vietnamese firm Minimal Design, created a unique staircase that provides plenty of storage, as well as space for a bathroom.
As the house is small but very tall (4 floors), the designers decided to make the space underneath the stairs functional, and as a result, they created a small powder room hidden behind a door at the highest point.
Not only is there a bathroom, but there are also three cabinets hidden within the white wall, creating spaces to store shoes and other small items.
