Translucent stairs

On one side of the wall, there is
the wooden board that can be folded.
It is convenient for old people or
students to carry heavy objects
upstairs

I design a lot of light belts on the
wall. The sides of the stairs are
made of glass. The sunlight can illuminate the staircase through the
glass during the day, and the light
of the light belts can illuminate the
staircase through the glass at night.
