CAA architects

West Mountain Innovation Valley | Beijing Collaborative Innovation Park is a large-scale office complex nestled at the foot of Beijing’s Western Hills. The project covers approximately 12 hectares with a total floor area of around 288,000 square meters. Liu Haowei and his team CAA architects have been responsible for the project’s master planning and architectural design since 2020. Located adjacent to Beijing’s historic Three Hills and Five Gardens and positioned within the northern expansion zone of Zhongguancun in Beijing, the project has been recognized as one of Beijing’s 100 Key Science and Technology Innovation Projects.

Rooted in Liu Haowei’s concept of Oriental Futurism, CAA uses Shanshui Valley (valley of mountains and waters) as a design axis, assigning distinct identities to the three plots: West·Mountain, North·Yard, and East·Creek.

North·Yard, the largest plot and the first phase of Beijing Collaborative Innovation Park, covering a total construction area of approximately 111,000 sqm. CAA combines traditional courtyard layouts with natural landscape imagery, balancing the concept of an enclosed courtyard and the overlapping mountain ranges. This culminates in the design concept of the ‘Mountain Courtyard.’

Mountain-shaped towers rise from the ground, while the surrounding podium forms a cloud-like ring around them—light, dynamic, and fluid. Together, they create a courtyard-inspired horizontal spatial interface. The architectural cluster engages in a dialogue with the Western Hills. Based on the harmonious concept of oriental philosophy, it integrates traditional imagery with futuristic technology and creates a vision of oriental romanticism with mountains, river valleys, and courtyards.

CAA has established a comprehensive green sustainability system for North·Yard, which incorporates a series of sustainable strategies and technologies, including natural ventilation, utilization of the chimney effect, mitigation of the heat island effect, noise control, rainwater collection, and water-soil conservation. Together, these measures enable the project certificated by China Green Building Council (CGBC) with the highest three-star qualification.

Interwoven multi-level natural landscapes create a vertical city garden in North·Yard, achieving an actual greening rate of 40%. It maintains an ongoing dialogue with the natural and cultural landscapes of the Western Hills and Fragrant Hills. From the mid-slope, Central Park and the site’s internal landscape merge seamlessly, resembling water flowing through rocks and generating ripples layer by layer. This dynamic oriental spirit surrounds the mountain-shaped towers.

North·Yard was completed in June 2025.
