Architecture firm Moon Hoon has designed a modern concrete home in Jeju-si, South Korea, and included in the design, is a custom-built bookshelf that follows the line of the stairs.
Connecting the various levels of the home, the staircase was created as an eye-catching element in the interior, with the wood shelving lining the walls.
The shelving, which has been built into the wall, is lined with wood that matches the stair treads.
The lower shelves of the built-ins also include hidden lighting, which allows the stair treads to be easily seen.
Above the stairs and the bookcase is a skylight with lighting that shows off the geometric lines where the walls meet the ceiling.
