HIDDEN WINDOWS. Need I say more??? - "Located in what is known as the Godzilla House by Chae-Pereira Architects in Seoul, Korea, these suspended stairs float along a curved wall and are lit by the hidden windows above."
I like the color but would swap out the hot pink accents with blue/soft teal and grey undertones as my secondary accent color with the cheery lime. 1 cheerful color is enough for me in an office space.
