Beijing Siheyuan

Beijing Siheyuan

Among the numerous alleys of varying sizes in Beijing, there are many courtyard-style residences enclosed by houses on the east, south, west, and north sides — these are siheyuan.

The main gate of a siheyuan is typically situated at the southeast or northwest corner. The northern house in the courtyard is the principal room, built on a brick-and-stone platform foundation, making it larger than the other dwellings and serving as the residence of the household head. On either side of the courtyard are the eastern and western wing rooms, which are where the younger generations live. Corridors are built between the principal room and the wing rooms for walking and resting. The enclosing walls of the siheyuan and the street-facing buildings generally do not have windows facing outward, making the courtyard environment enclosed and tranquil.

Beijing has siheyuan of various sizes, but regardless of their scale, they all consist of courtyards enclosed by buildings on all four sides. The simplest siheyuan has just one courtyard, while more complex ones may have two or three. The large, luxurious mansions inhabited by wealthy families are usually composed of several siheyuan arranged in parallel, often separated by an interior wall.

A Beijing siheyuan is a type of courtyard architecture. The term “courtyard” refers to a central open space surrounded by buildings on all four sides — hence the name “courtyard.” Each household occupies one residence, which may consist of multiple courtyards. The courtyard is organized along a central axis, with the northern house as the principal room, the eastern and western houses as wing rooms, and the southern house with its door opening to the north, hence called the “inverted seat.” When a family becomes wealthier or has more members, they can build a compound consisting of two connected courtyard sets.

Wealthy families who wish to display their affluence may construct three or four connected courtyards. Within the courtyards, flowers, fruits, and trees are planted for ornamental purposes. Smaller courtyards may have 13 rooms, while larger ones may have 30 rooms in a single courtyard. Courtyards with two compounds may range from 25 to 40 rooms, all on a single level. The back wall of the wing rooms serves as part of the courtyard wall, with additional brick walls constructed at the corners. Large siheyuan are enclosed by high exterior walls without windows, giving them a defensive appearance. The entire family lives comfortably within the courtyard; at night, the gates are closed, ensuring tranquility ideal for family-centered gatherings. During the day, the courtyard’s plants and trees create a beautiful scene, with fragrant flowers and fresh air in the evening. Family members sit together in the yard to enjoy the cool, relax, chat, and drink tea, fostering familial harmony. What happens in the courtyard remains unseen by outsiders, aligning with Chinese customs. The living spaces within the siheyuan are divided: the elderly reside in the northern room (the main room), the central area serves as a large living room (the central hall), the eldest son stays in the eastern wing, the second son in the western wing, servants in the inverted seat, daughters and young ladies in the rear courtyard — each area maintains its own privacy.

The design and construction of Beijing siheyuan are relatively simple, using uncomplicated materials — no steel or concrete, just grey bricks, grey tiles, and a combination of brick and wood structures. Of course, the primary structural standard is wooden, which is lightweight. In the event of an earthquake, they are rarely toppled, indicating that siheyuan are earthquake-resistant. The overall architectural color scheme is grey and subdued, giving a very simple impression yet ensuring a comfortable living environment. Courtyards in other regions are fundamentally similar to those in Beijing, though they vary in size, height, and materials, with only slight differences in style. These courtyards represent an important architectural heritage of the Chinese people.

The differences between Beijing siheyuan and those in other regions are as follows: In the Beijing area and surrounding regions, siheyuan are built with a central axis of symmetry. The main gate is located southeast of due south, and it does not face the principal room — that is, the gate is positioned at the southeast of the courtyard. This arrangement follows the Bagua (Eight Trigrams) directions: the principal room faces north, considered a "Kan" residence. For a Kan residence, the gate must be placed in the "Xun" direction, which is southeast. Opening the gate in the southeast ensures unending wealth and smooth financial flow, hence the preference for a “Kan residence with Xun gate.” Therefore, the main gate of a Beijing siheyuan is situated in the southeast. This placement is determined by feng shui principles and is unique to the Beijing area; other regions do not follow this practice.

Yuan Dynasty

Established in 1271, the Yuan Dynasty made Beijing its capital, transforming the city into the unified national capital of China. Both historical relics and written records indicate that Beijing underwent epoch-making changes in urban development. Dadu (the capital of the Yuan Dynasty) was a world-renowned metropolis at the time, and its construction included large-scale residential areas, with hutongs and siheyuan becoming fundamental features of Dadu.

Residential buildings within Dadu were distributed along small streets or hutongs. In 1965 and 1972, archaeological excavations were conducted at the site of a Yuan Dynasty residential area inside Xizhi Gate in Beijing, located east of Yushunfang and approximately at the eighth hutong north of Heyimen — a siheyuan residence covering eight mu of land. According to Yuan regulations, “eight mu equaled one unit,” which largely matches this case. The overall layout of the site fully reflects the architectural style transitioning from the Song-Yuan period to the Ming-Qing period.

Judging from the site plan, the excavation likely covered the northern part of the main buildings of this siheyuan (Figure 1). Its northern section might have been a backyard garden or similar feature. From the southern gate to the backyard garden, the distance corresponds to that of two hutongs in Dadu, which was about 70 meters.

Ming Dynasty

After the establishment of the Ming Dynasty, the socio-economic situation developed rapidly. The Ming capital was moved from Nanjing to Beijing, and tens of thousands of wealthy households were relocated from regions such as Zhejiang and Shanxi, significantly boosting Beijing’s economy. During the Ming period, brick-making technology reached unprecedented levels, further promoting the development of construction and residential building. Books such as the "Lu Ban Jing" and "San Cai Tu Hui" emerged during this era, indicating that not only was residential construction practice highly active, but there was also theoretical guidance. To maintain feudal order, the Ming Dynasty imposed strict regulations on the architecture of residences for different social classes, covering aspects such as system, scale, and color. Illustrations in texts like the "San Cai Tu Hui" and "Lu Ban Jing" show that Ming residences still followed the siheyuan form of the Yuan Dynasty.

Qing Dynasty

After establishing its capital in Beijing, the Qing Dynasty extensively absorbed Han culture and fully inherited the architectural style of Ming-era Beijing, including its residential buildings — particularly the siheyuan. In the early Qing period, a policy of separating Manchu and Han residents was implemented, relocating all Han people to the outer city while reserving the inner city for Manchus. This measure objectively promoted the development of the outer city and allowed for further refinement of the inner-city residences. The most representative residential architecture of the Qing Dynasty was the palace-style mansion — large and medium-sized siheyuan inhabited by bureaucrats, landlords, and wealthy merchants. The Qing Dynasty marked the golden age of Beijing siheyuan development. However, from the late Qing period onward, as China gradually became a semi-feudal and semi-colonial society, the development of siheyuan began to decline.

Under the influence of foreign invasions and the infiltration of Western culture, traditional Beijing residential architecture was also affected to some extent. Some siheyuan built during this period incorporated Western architectural decorative elements to varying degrees, the most typical being the appearance of Yuanmingyuan-style wall gates. Those deeply influenced by the “Western Learning Spreading to the East” movement, eager to showcase themselves as representatives of the “new school,” also built “Western-style houses” within their compounds, though such cases were rare. Overall, during this period, traditional Beijing residences largely retained their Ming-Qing architectural styles.

War of Resistance Period

The invasion of Japanese imperialism brought significant changes to Chinese society. Due to inflation and rising prices, the economic conditions of citizens deteriorated. Many residents who once lived in single-family siheyuan could no longer afford to maintain their properties and had to rent out extra rooms to supplement their income. As a result, housing per resident decreased, while the number of tenants in the courtyards increased. Single-family siheyuan gradually transformed into multi-family shared compounds, altering the original residential nature of the siheyuan.

After 1949, the use of traditional Beijing siheyuan underwent fundamental changes. Due to shifts in ownership systems, many mansions and residences left over from the Qing Dynasty, once privately owned, became public property. They were no longer occupied by the former aristocracy but instead repurposed as housing for government agencies, schools, hospitals, factories, kindergartens, clubs, and other public uses. The change in functional use created irresolvable conflicts between the buildings and the needs of their new occupants. Ultimately, rather than people adapting to the buildings, the buildings were modified to suit human needs. Those still used as residences were no longer single-family homes but transformed into multi-family shared “courtyard compounds.” These changes made it increasingly difficult for siheyuan to retain their former depth, serenity, elegance, and warmth. The division, alteration, and fragmentation of siheyuan became widespread.

Cultural Revolution Period

The devastation of the Cultural Revolution was the most severe period for Beijing siheyuan. In the late 1960s, the campaign to “eliminate the Four Olds” led to the destruction of exquisite brick carvings, wood carvings, stone engravings, and painted decorations in siheyuan. Countless invaluable artworks were smashed to pieces or covered in plaster, with only a few surviving. This was soon followed by the nationwide “bomb shelter” digging movement for “war preparedness,” which further damaged the original layout and drainage systems of siheyuan, resulting in serious consequences. The 1976 Tangshan earthquake exacerbated the situation. To protect against seismic disasters, “earthquake shelters” were crammed into already crowded courtyards. As the population grew, these shelters were later converted into permanent structures, completely altering the appearance of the siheyuan.

Reform and Opening-Up Period

After the Cultural Revolution, Beijing’s urban development master plan established policies for the protection of siheyuan, curbing the aforementioned deterioration to some extent. However, this was soon followed by large-scale urban redevelopment, creating sharp conflicts with siheyuan preservation. Constructive destruction occurred frequently, and resolving the tension between redevelopment and conservation remains a topic requiring serious study.

In the over ten years since the early 1980s, a new phenomenon has emerged in Beijing’s siheyuan districts: some overseas Chinese who relocated to Beijing and individuals who became wealthy during the reform and opening-up period, driven by nostalgia and a strong pursuit of traditional culture, purchased old siheyuan in concentrated areas and renovated them into new ones. Some long-term foreign residents in China also acquired land to build homes, moving into traditional Chinese dwellings. These new siheyuan mostly retain the traditional exterior appearance and colors, while the interiors are equipped with modern amenities such as heating, plumbing, bathrooms, air conditioning, and high-end furnishings. The renovated siheyuan have transformed from multi-family shared compounds back into single-family private residences, featuring spacious courtyards, lush gardens, elegant scenery, and tranquil atmospheres — as if the siheyuan have returned to their heyday. This trend continues to grow vigorously. Whether this represents the revival of the siheyuan or the evolution of traditional residential architecture under new historical conditions is a topic not yet studied or defined. However, as a significant historical phenomenon, it has added a new chapter to the history of Beijing siheyuan development.

Places of Renown

The fame of Beijing siheyuan also stems from their unique structure, which is typical and representative within traditional Chinese residential architecture. Most Chinese residences are inner-courtyard style. In southern regions, the courtyards are small, with surrounding houses forming a single unit known as a “yixingyin” (literally “one seal”). This type of dwelling suits the southern climate, offering excellent ventilation and lighting. In contrast, Beijing siheyuan feature spacious and airy courtyards, with each of the four houses standing independently yet connected by corridors for convenient access, making daily life pleasant and the courtyard ideal for activities.
