Korea is one of the most densely urbanized societies in the world, and the physical form of that urbanization is overwhelmingly the apartment. Roughly sixty percent of Korean households live in apartments — not the low-rise or mid-rise residential buildings common in parts of Europe, but high-rise concrete towers arranged in large managed complexes called danji. This is not simply a housing preference. It is the outcome of specific historical, economic, and policy conditions that shaped how Korean cities were built during the country's rapid industrialization, and it has produced a residential design culture with its own consistent internal logic.
Korean apartments look similar to each other because they are, in important ways, designed according to shared conventions. The floor plan of a three-bedroom Korean apartment built in Busan in 1995 and one built in Seoul in 2015 will differ in finish and scale, but a person familiar with one will navigate the other without difficulty. The living room will be adjacent to the kitchen. The bedrooms will be separated from the living areas. The veranda will run along the exterior. The entrance will have a defined threshold. These conventions are not accidents or stylistic preferences. They reflect accumulated decisions about how domestic space should function, informed by the specific conditions of Korean urban life.

The Standard Floor Plan and Why It Exists
Korean apartment floor plans are typically described in terms of the number of rooms — bangsu — which in Korean residential terminology refers specifically to the number of enclosed rooms excluding the living room, kitchen, and bathrooms. A three-room apartment (sambang) has three separate enclosed rooms, typically used as bedrooms, plus the common living and kitchen areas. This counting system reflects a functional understanding of the apartment as a collection of private spaces arranged around shared ones.

The standard floor plan that dominates Korean apartment construction places the living room at the center of the unit with the kitchen adjacent or open to it, bedrooms arranged along the opposite side of the plan, and the veranda running along the exterior wall behind the living room. This configuration is so consistent across Korean apartment construction that it functions almost as a template, varied in proportion and finish but recognizable in structure across decades of building.
The logic behind it is practical. Placing the living room along the exterior wall — typically the south-facing wall in Korean construction, which maximizes solar exposure — gives the most-used communal space the best natural light. The bedrooms, which are used primarily at night, are positioned away from the main facade. The kitchen connects directly to the living and dining area to support the flow of meal preparation and shared eating. The veranda behind the living room serves as a buffer between the heated interior and the exterior, and functions as the utility zone that absorbs the domestic overflow the main rooms cannot accommodate.
This arrangement has been reproduced at enormous scale across Korean cities. The consistency is partly the result of construction efficiency — building similar units across similar floor plates reduces design and construction cost — and partly the result of the arrangement genuinely working well for the way Korean households use domestic space. Conventions persist when they solve problems reliably.
The Public Zone and the Private Zone
One of the most consistent organizing principles of Korean apartment design is the separation between what might be called the public zone and the private zone of the home. The living room, dining area, and kitchen form a connected sequence of spaces intended for shared use — by household members together and by guests. The bedrooms are separated from this sequence, accessed through a corridor that creates a spatial and acoustic buffer between the two zones.

This separation is more deliberate and more structurally enforced in Korean apartments than in many Western residential designs of comparable size. In a typical Korean three-bedroom apartment, a guest sitting in the living room has no sightline into the bedroom corridor. The bedroom doors, when closed, are acoustically and visually isolated from the main living area. The transition from communal to private space requires a physical movement through the plan rather than a simple turn of the head.
The reasons for this are partly cultural and partly practical. Korean domestic culture places significant emphasis on the distinction between spaces that are appropriate to share with guests and spaces that are not. The bedroom is unambiguously private — not a space guests enter, not a space whose contents or condition should be visible from the living area. The living room is the face of the home, maintained and presented accordingly. The floor plan reinforces this distinction by making it architectural rather than merely social.
The practical dimension is acoustic. Korean apartments are built at high density, and the walls between units, while structurally solid, transmit sound. Within the unit, the separation of bedroom zone from living zone reduces the degree to which activity in the living room — television, conversation, cooking sounds — penetrates the sleeping spaces. In a household with children, or with members who keep different hours, this matters.
Room Size and the Hierarchy of Space
Korean apartments allocate space according to a clear hierarchy that reflects how rooms are actually used rather than treating all rooms as equivalent. The living room is typically the largest single space in the unit. The master bedroom is the second largest. Secondary bedrooms are smaller — often substantially so by Western standards — and are understood as sleeping and storage spaces rather than multipurpose rooms.
This hierarchy can surprise visitors from countries where the bedroom is culturally central as a personal space — a room for studying, entertainment, socializing privately, and sleeping. In Korea, and particularly in the urban apartment culture that shapes most Korean domestic life, the bedroom's primary function is sleeping and dressing. The living room is where household life takes place. The bedroom is where you go to sleep.
The result is that living rooms in Korean apartments tend to be proportionally generous relative to the overall unit size, while bedrooms tend to be proportionally compact. A sixty-square-meter apartment will typically have a living room that feels comfortable and spacious, and bedrooms that feel efficient rather than generous. This is not a design failure or a cost-cutting measure — it is a deliberate allocation that reflects the actual distribution of time and activity within Korean domestic life.
Kitchen Design and the Logic of Compactness
Korean apartment kitchens are compact. In a standard three-bedroom unit, the kitchen occupies a relatively small footprint, organized around a linear or L-shaped counter arrangement with overhead and under-counter cabinetry running its full length. There is rarely a kitchen island or a breakfast bar. The kitchen is a workspace, not a social space.
This compactness has a functional basis. Korean cooking is intensive — it typically involves multiple burners running simultaneously, significant preparation work, and the management of numerous ingredients and condiments. A kitchen designed for this kind of cooking needs well-organized storage, efficient counter space, and good ventilation more than it needs floor area. The built-in cabinetry that runs the full height and length of the kitchen wall provides the storage capacity; the counter space is compact but uninterrupted; the range hood handles the ventilation demands of high-heat cooking.
The kitchen's relationship to the living and dining area has shifted over time. Older Korean apartments maintained a more separated kitchen, with a wall or partial partition between the cooking space and the dining area. Contemporary Korean apartment design has moved toward the open-plan kitchen that is now standard in new construction — the counter faces the dining area, and the kitchen is visually connected to the living space. This shift reflects both changing cooking habits and a desire for the light and spatial openness that a fully enclosed kitchen cannot provide in a compact unit.
The Danji as Urban Unit
Korean apartments are rarely designed as standalone buildings. They are built as danji — large residential complexes that group multiple towers on a shared site with shared infrastructure: underground parking, landscaped grounds, community facilities, management offices, and controlled perimeter access. The danji functions as an urban unit in its own right, a self-contained neighborhood within the city.
This model of residential development has implications that extend beyond the individual apartment. The danji provides amenities that a single building cannot: children's playgrounds, outdoor exercise equipment, walking paths, community halls, sometimes convenience stores or small retail. The managed perimeter and the shared maintenance system produce a level of environmental quality and security that individually owned and managed buildings rarely achieve.
For Korean apartment residents, the danji is the immediate residential environment. The quality of the complex's management, the condition of its shared spaces, and the social composition of its resident community matter significantly to how the apartment inside it is experienced. The apartment unit and the complex it belongs to are understood as a package rather than as separate considerations, which is why Korean real estate discourse discusses danji reputation and management quality alongside unit size and price.
The design of Korean homes, in the end, cannot be separated from the design of the urban systems they inhabit. The apartment is efficient because the complex manages what the apartment cannot. The floor plan is optimized because the building type is standardized. The spatial logic of the unit reflects the spatial logic of the city that produced it — dense, organized, and built around the practical realities of a lot of people living well in limited space.
