This project is an ideal model of "home + office". The setback becomes the best view point of the whole house, but also an "ambiguous" space that is compatible with various functions. The designer has positioned it as a space for "useless use", which is obviously a high level of resting body and mind and even philosophical sublimation for the setback outside the space itself. The design hopes to provide a sense of isolation from the city dwelling. where the interior and exterior environments blend together to form an order that extends from the near to the far side of oneself.
