半地下室 | Semi-basement
In addition to the typical hutong courtyard, some of the houses in Xicheng District of Beijing are apartment buildings built in the 1980s. Although these buildings are not as old as hutong houses, there are still many inconveniences for people's life today, which need to be renovated to improve the quality of the space.
▼居民楼外立面 Facade of residential building
The renovation project is a house near Deshengmen in Beijing. The biggest "feature" of this house is that it is a semi-basement. The house has a total of 65 square meters and has 2 bedrooms, and the apartment is permeable from north to south as a whole, but due to the special topography of the whole unit building, the owner's house has become a semi-basement, and the south side of the room is a normal first floor house, which can be lighted normally, while the north side of the room is half below the ground, so only two very small high windows are used for daylighting, which makes the indoor light dim and humid.
▼原始户型及现状 The original plan layout and site photo
This 65-square-meter semi-underground house accommodates the life of the owner's family of five. Residents include couples, two children, and elderly grandma. Since only the south side has normal lighting, the activities of the family are basically concentrated in the master bedroom on the south side. Originally, there was only a room of 65 square meters, and the space on the north side was almost unused, reducing the interior use space. Moreover, the dampness, darkness, and poor air quality caused by the housing pattern are not conducive to the physical and mental health of the elderly and children. Too many problems need to be solved urgently. How to let the sunlight shine back into the room and make use of the space on the north side of the room is a major difficulty in this transformation.
引入光线 | Natural lighting
We set the renovation goal of this renovation as a livable home with four rooms and three halls, solve the three major problems of ventilation, lighting and humidity at one time, and create a multi-functional space to meet the needs of a family of five people to study, work and play Multiple living conditions.
▼半地下室外立面 Semi-basement facade
The first thing to be solved is the physical problem of the house-daylighting. The area of the window outside the south master bedroom is expanded to increase the lighting surface, and the previous balcony space is also been used. Since the owner ’s house is located on the first floor and there is a small yard on the south side, we have also organized this yard so that the owner can enjoy the view of the yard from the inside, and also provide an activity space for the elderly and children. The windows on the north side of the house have also been expanded within a reasonable range. The daylighting surfaces of the outside windows are all increased.
▼室内光线穿透细节 Indoor light penetration details
In order to increase the indoor light, we designed a corridor in the interior that allows light to pass directly, so that the light from the north and south can spread indoors without obstruction. In order to ensure that the light is not blocked, glass sliding doors and sliding doors are used at the partitions of the space to make this corridor of light completely transparent.
折叠空间 | Folding space
If you want to accommodate a family of five in a space of 65 square meters, if you want to achieve four rooms and three living rooms, if you only consider the plane layout, it is difficult to achieve. After all, a skillful wife cannot make meals without rice, there is no area, and there is no place to put the function. So we introduced the " Folding space ", so that the function of the space can be changed, so as to increase the utilization rate of the space, but also create more space experience.

The original master bedroom is located on the southernmost side of the room with better lighting, so the main areas of the family's activities are concentrated in the master bedroom. In this transformation, we still maintain the original position of the master bedroom. Since this is the best place for the whole family to daylight, we also set the location of the living room here and performed a compound superposition of functions. During the day, the folding bed in the master bedroom can be folded away, and the entire space becomes a space for family activities. The elderly can sit on the sofa or prunes flowers and plants in the yard. Children can play, bathe in the sun, play the piano and learn. At night, when resting, the folding bed is put down and the glass sliding door on the outside is closed. This becomes an independent and private bedroom.

▼餐厅与客厅 Dining room & living room
The previous house did not have enough space to accommodate the dining room, and the family just put a table in the aisle for dinner. During the renovation, we set up a multifunctional space where the dining room and living room are combined beside the kitchen. The dining table can be folded and stored, and can also be expanded to adjust to different sizes of desktops. The largest table can accommodate 10 people to eat, not only to meet the family's daily meals, but also invite friends to dinner. When the dining table is fully folded, the sofa can also be expanded into a sofa bed, which serves as a temporary bedroom for guests.
▼厨房与餐厅之间的孔洞 The hole between the kitchen and the dining room
▼开放式厨房 Open kitchen
The kitchen before the renovation is next to the master bedroom on the south side, but because there are walls around it, if you don't turn on the light, you can't reach your fingers. The kitchen has an open layout, spacious and bright. In the renovation, we removed the original closet in the kitchen, forming a hole connecting the kitchen and the dining room, which can introduce the sunlight from the south into the kitchen. In terms of function, it also facilitates the delivery of dishes and creates an interesting interactive atmosphere between the kitchen and the restaurant. Parents can also observe their children at any time while cooking to avoid danger.
▼干湿分离卫生间 Wet and dry separation toilet
The original bathroom area is less than two square meters, and the five people in the family use it together. The experience is extremely poor. During the renovation, the original toilet was moved one meter to the west to expand the area of the toilet and an additional toilet was added to allow five people to use the toilet comfortably, and the wet and dry separation was done so that users would not interfere with each other.

Because the north side is a semi-basement, the original north bedroom has almost no lighting. The wet walls all over the year have been covered with mildew spots, and the items are placed in a mess. It has become a "debris room" in the home. During the renovation, the room was designed as a tatami room, and the table was raised. It can be used as a small living room. Family or friends can drink tea and chat together here. The outside of the space is partitioned with transparent sliding doors to ensure privacy while not affecting the lighting of the entrance hall. Putting down the tabletop can turn it into an activity space for two children to play. After closing the door at night, you can transform into a bedroom. This bedroom considers that the owner's son needs to be divided into rooms when he grows up, and then he can be used as his bedroom.
The entrance hall is a huge hug for the returning family. In this project, the entrance is very small and directly faces a long corridor. In the transformation, the wall opposite the entrance is divided into two, a photo wall on the top, a locker on the bottom, and a shoe cabinet on the side near the entrance. The overall use of black and white and wood color gives a warm and soft feeling. Part of the wall is covered with blackboard stickers, so that children can write and write on the wall at any time, retaining their nature.
