Bit (sunlight), Sol (pine tree), and Maru (in-between space between room and room) are three elements from traditional Korean housing, Han-ok, that can be reproduced in a modern house. By reproducing the structure of a well-lit house at the scale of a Han-ok, a small courtyard settled in a square mass. The material and finishes from the pine tree bring warmth and softness to the houses. The Maru replaced a living room as the central space of the house. The living room of Bit-Sol-Maru house do not have a TV and a sofa. The scenery from the Maru that constantly changes 24/7.
