Renovation of the Jiakaxia Ancient Courtyard: Preserving Tibetan Heritage in Lhasa

Located in the heart of Lhasa, China, around the vibrant Barkhor Street, the Jiakaxia Ancient Courtyard stands as a unique testament to the fusion of Tibetan culture, urban life, and historical architecture. Designed and executed by hyperSity Architects in 2024, this 1,100 m² project exemplifies the delicate balance between heritage conservation and modern urban adaptation.

Historical and Cultural Significance

The Jiakaxia Courtyard, named after the Tibetan word for "Magpie Pavilion," reflects centuries of Han-Tibetan harmony and social integration. Nestled amidst the bustling commercial and religious fabric of Barkhor Street, the courtyard has historically housed monks, lay officials, shops, and civilian homes. This unique mix created a "temple-market syncretism," a spatial configuration that highlights urban Tibetan heritage.

Originally, the courtyard consisted of traditional Tibetan stone masonry at the front, complemented by a late-1990s modern addition at the rear—a bookstore known as Paradise Time Bookstore. Over time, the building fell into disrepair, requiring thoughtful renovation to preserve its cultural and architectural value.

Renovation Philosophy

The renovation of the Jiakaxia Courtyard, led by Shi Yang, was initiated by a devout Nepalese merchant with a vision to rescue the millennium-old structure. The project adopts a dual approach, restoring the historical front façade while reimagining the rear as a serene, modern Pan-Tibetan-Pan-Chinese courtyard.

By integrating traditional Tibetan construction techniques with modern materials like concrete, light steel, and color steel panels, the architects overcame the spatial constraints of traditional thick-walled, small-windowed buildings. Large-span spaces and floor-to-ceiling windows now enhance natural light, improve functionality, and cater to contemporary urban life.

Architectural Design and Spatial Experience

The renovated courtyard preserves the historic circulation of the prayer path, allowing visitors to experience the architecture as a spiritual journey. Entering from Barkhor Street, one passes through a central exhibition hall leading to an ancient sacred well, historically used by the Sixth Dalai Lama, Tsangyang Gyatso, for tea. An atrium above the well frames the sky, while new structures respectfully bypass this cultural landmark.

Visitors can ascend to the rooftop via inner courtyard stairs, enjoying panoramic views of the Potala Palace, Jokhang Temple, and the lively Barkhor Street below. This rooftop functions as an urban 观景台 (viewing platform), combining physical circulation with visual exploration, making the 1,100 m² space feel labyrinthine and dynamic.

Craftsmanship and Materiality

The renovation avoids extremes: it neither superficially applies Tibetan motifs to modern frameworks nor relies solely on costly traditional techniques incompatible with contemporary needs. Instead, it employs an integrated construction method: concrete frameworks reinforce the historical stone walls, which are thinned for better light and flexibility while maintaining authenticity.

A prime example is the Jiabalé stone-laying technique, traditionally earthquake-resistant, adapted here with 40 cm-thick walls reinforced with steel bars every 50 cm. Wooden doors and windows, crafted by skilled carpenters from Shannan Prefecture, feature Basu eaves and Feizimu motifs, harmoniously embedded within the stone and concrete structure. Exterior walls are finished with historic sheep's milk plaster from Yangbajing, combining white lime with milk, sugar, and honey for durability and texture.

Social and Urban Impact

Today, the Jiakaxia Courtyard serves as a cultural hub, where public life extends into private spaces. The open "pocket courtyard" connects multiple levels and functions, enabling interactions between spiritual seekers, urban wanderers, and local residents. Arched pathways, staircases, and wall details echo the design of the sacred well, enriching the three-dimensional spatial experience.
