A cost-effective house with moonlight through selection and focus. What kind of house does the owner of the house, who built his first house without asking his parents for help, live in? Lee Sang-hoon and Kim Hye-jin, who live in Yangpyeong-gun, Gyeonggi-do. A family that rented a house in Yangpyeong, where they had no connection, for the education of their two daughters. After that, they lived in an apartment, but the house life kept coming to mind. “When we lived in Yangpyeong, this was really good.” The owner and his wife kept thinking about the house life in Yangpyeong, even though it is a more convenient and comfortable apartment than a house. The apartment they were living in went up in value more than expected, and with the seed money they luckily got, the couple decided to build their first house in Yangpyeong. This place, ‘Hwajopungwol’, uses three exposed concrete techniques to make it feel like an art gallery. The wife, Kim Hye-jin, wanted to create a special house located on the roadside where people passing by would take a second look at it as a house or a cafe. However, despite the eye-catching exterior, the interior only has an ordinary master bedroom and children’s room… Where on earth is the point of this house hidden? Entering the living room, a large, round ceiling catches the eye. And a panoramic window that stretches out like a belt. The wife, Kim Hye-jin, says there is a special reason why she designed such a large ceiling. She says that when they lived in a country house in Yangpyeong, the faces of her family members shining brightly in the moonlight at night when everyone was asleep remained in her memory. Did she share her wife’s special memories? Her husband, Lee Sang-hoon, decided to bring the moon into the house according to his wife’s suggestion. However, building a round ceiling was not as easy as he thought. It is said that the formwork alone took almost a month. In this way, the living room, a special space unique to this house that was created after a long period of effort. It has become the focal point of this house, giving warm sunlight when the day dawns and bright moonlight when the day darkens. The couple’s house is so coveted that even the architect wants to sell it. Here, the couple lives with their two beloved children, greeting nature every day. “This house is like a child to me.” They set the living room as the focal point of the house, and removed design-related finishing elements. The couple who built a house with good cost effectiveness through selection and focus. After moving into this house, the wife, Kim Hye-jin, says she came to respect her husband even more. We visit the house of the couple who are expected to grow like their children and make memories together. Building a three-story house with good cost effectiveness through pre-purchase and post-design. Is there an owner who built his first house in his 30s, a relatively young age? The couple, Kim Geon-hyung and Lim Hye-mi, who live in Yongin-si, Gyeonggi-do. They are experiencing special and precious things earlier than others by building a house at a young age. Not only is the background of the lush forest visible, but the work results are also good cost effectiveness! How did this couple raise the funds to build a special and cost effective first house? “We started with just 3 million won.” The husband, Kim Geon-hyung, started a food truck business with 3 million won he saved from a part-time job during his college years. Since he didn’t have any money, he built his construction skills by touching the electricity himself and exploding, and by participating in the construction of stores to save on construction costs. Then, he was lucky enough to receive business investment, and before he knew it, he was able to rise to the position of CEO, operating four stores. The husband tried something different from others to save money. Instead of purchasing a ready-made product after designing, he designed it to fit the ready-made product. The couple was able to save on interior design costs through a smart architectural plan. The owner couple is happiest when they sit on the sofa that fits perfectly, communicate with their children on the stairs, and look out at the scenery outside. They can enjoy the four seasons up close through the natural forest connected to the living room. “It’s a house that changes according to the children’s life cycle.” Another space that was specially planned to save money awaits in this house. The house was built with the children in mind, considering the growth process they would go through as they grow up, and considering the possibility of easily changing the structure. It is currently used as the wife’s studio, but when the children go to school and want their own rooms, they can remodel this studio into the children’s rooms. By designing the space to be flexible in this way, they were able to reduce remodeling costs in the future. Unlike the 1st and 2nd floors, which are made o
