The private room on the second floor is an attic like a hiding place. Its small indoor space has advantages such as "construction cost is low," "easy to clean", and "utility cost is low."

"Large terrace"
About 26 square meters of large terrace, which is half of indoor space, has a continuous relationship and a discontinuous relationship with the indoor space at the same time. Continuity contributes to make the small house look spacious, and discontinuity contributes to make indoor space thermal environmentally small. In addition, the role of the terrace changes greatly depending on the season.

In winter, it is covered with a transparent film, and the room becomes a greenhouse. It will help to make your life comfortable in winter.
