The sago stone wall is high enough to almost touch the eaves, and there is a narrow and long gap between the eaves line and the fence to allow ventilation and light. A glass block is inserted between the accident stones to relieve the pressure caused by the high fence. The boundary is made clear with thick thought stones, but the inside and outside are connected slowly and vaguely through glass blocks. During the day, the light comes into the niche yard of Andaecheong, and at night, the light leaks out in a grid pattern.

​

However, except for this gap between the Daecheong and the northern wall, the exterior space remaining between the U-shaped plane and the site boundary is being used without any gaps. The toilet was long and narrow in the back of the main room, and a front window was opened to the niche yard behind Andaecheong. This window is made of special glass that allows you to see the outside from the bathroom but not the inside. And behind the opposite room, a staircase leading down to the new basement was placed under the cross room and the Daecheong. It is decorated as a music room, and it is the music listening room that the owner cherishes the most. It's a narrow underground space, but it's not stuffy because you go up the stairs looking at the niche.

​

The space in the back of the kitchen is a multi-purpose room, with a toilet on the south side of the lower room and an interior space on the outer yard of the doorway, with a storage cabinet and desk and a toilet on the other side. A shoe rack was installed on one side of the doorway. As such, the outline of the courtyard is maintained intact, but the space between the U-shaped hanok and the site is utilized as a practical space. Even when viewed from the inside, the space such as storage space and toilet is completed outside the pillar line, keeping the outline of the interior space of the hanok intact.

​

In addition, the windows are reconfigured in various practical ways, such as glass doors, insect-proof doors, and paper-wrapped doors, so that they can be opened and closed in an appropriate combination according to the season. From the inside, the window frame is thicker inside the column line, but the wires are also inserted between them, so the outline of the interior space is neatly finished.

​

It was thanks to Min Seo-Hong, the eldest son of this house, who was working at the architectural culture and architects office at the time, that he was able to find the leftover space in every corner of the house and use it one hundred and twenty percent. While directly in charge of designing and supervising Seo Ha-jae, he found niche spaces according to the needs and tastes of each family member and restored them to custom spaces.
