The couple, who have lived in a country house for 12 years, have 100 points in their skills, and a 100% usable house. The couple, who previously built a house and lived there for 12 years, considered a ‘100% usable house’ the most when building their second house. The couple wanted a house that would not require much maintenance for the next 10 or 20 years. What kind of skills are hidden in a house that has eliminated useless and flashy things and filled it only with the necessary things based on their experience in housing? The wife, Nam Mi-young, thought that the garage space could be used as an indoor space. What she realized while living in a country house was that visitors came unexpectedly often. For guests who visit briefly, they changed the garage near the front gate into a welcome room, and used it as a space that is not burdensome to both the guests and the owner. Another part of this house that is considerate of guests is that the guest room is separated like an annex and even the bathroom is separate. Also, the structure designed to connect the kitchen – living room – bedroom through the entrance, and the structure that places the bathroom next to the entrance and in front of the main door to separate it from the house are sensible points that take into account everyone’s privacy. This is also an idea born from the know-how of housing experience. “Where and how you spend your money is more important.” The biggest obstacle in building a house is, as expected, the budget issue. Through one experience, the owner couple realized that ‘where and how you spend your money’ is more important than ‘how much money you have.’ Instead of boldly eliminating the second floor and attic space, which are difficult to walk on, they increased the number of bathrooms to four. In addition, instead of the island table that is difficult to keep clean, they completed a kitchen that is appropriately hidden and reduced through a large pantry and kitchen screen. In addition, the husband, Jo Gil-ho, simplified the landscaping of the garden to make it easy to manage with a rock that came out during construction and a pine tree. Instead, they built a large warehouse to store tools necessary for country living, and they are adding satisfaction to the couple’s life through ‘selection and concentration.’ “A house that won’t be touched even after 10 or 20 years” A couple in their 60s who built their last house with the intention of living there for the rest of their lives. While fancy and pretty things are good, they now think that a house without defects and that they can use for a long time is more important. Rather than a house that is flashy, they wanted a simple and sturdy house that blends in with nature, to the point that the roof shape was modeled after the mountain. Based on their many years of experience in housing, we visit the house of a couple who chose to ‘subtract’ rather than ‘show off’, and it is 100% usable. Minimum space, maximum use! A small but strong compact house Kim Jong-hyeok and Kim Na-ri, a couple living in Yongin-si, Gyeonggi-do. While raising two sons, they decided to build a house to be free from noise between floors, but it wasn’t easy to leave the city center because of the educational infrastructure. In a large city housing complex notorious for expensive land prices, the couple who built their house on a narrow lot thought about a house that they could use efficiently. What is the secret to this house’s space utilization that makes even a small house look spacious? “If functionality and aesthetics conflict, let’s choose functionality.” After deciding to build a house, the couple’s principle was to prioritize ‘functionality’ over ‘aesthetics.’ So instead of a house that could be designed in various shapes, the couple built a rectangular house as a passive house. Thanks to this, they can spend warm winters and cool summers. Although rectangular, this house, which looks like a ‘D’ by connecting the second floor of the main building to the rooftop of the annex, has a pergola-shaped parking lot thanks to the connecting bridge. The parking lot with a ceiling is used not only as a parking space, but also as a party space by placing a table, and as a space for the husband’s hobby of woodworking on rainy days. “Since it’s a small house, let’s maximize space efficiency.” Kim Na-ri, the wife, thought about how to utilize the house as much as possible while thinking with her husband. As much thought was put into utilizing the space, all the spaces in this house are designed to be used for various purposes. On the first floor, instead of a sofa, a platform was created using steps to create a space for children to enjoy, and the steps created by creating the platform were used as storage space by putting in storage cabinets. And the stairs with bookshelves on the walls are not just a space for going up and down, but also a study for children to read books. In addition, the room connected to the living room on
