Huzhou is the core city of the economic circle around Taihu Lake and the birthplace of the "Two Mountains Concept." China Energy Conservation · Taihu First Tower is located in Huzhou Science and Technology New City, adjacent to the high-speed railway station, becoming the "first sight" of Huzhou for visitors. The site's external context, formed by Xisai Mountain to the west and Kang Mountain and Xifengyang Park to the south, not only provides excellent landscape conditions but also aligns with the "Two Mountains Concept," inspiring the design concept of "flowing landscape."
To match its prime location and urban image, the project is positioned as a "new city landmark with a strong sense of technology." Limited by site capacity and height, the key design challenge was to create this technological feel while integrating with nature and the city. Starting from balancing and connecting the multifaceted relationships between the building, site, city, and nature, and leveraging gad's expertise in structural design, abstract concepts were translated into concrete spatial forms.
Resolving Building Volume, Optimizing "Seeing and Being Seen"
To achieve "views for every unit and flexible sales," the design decomposes the massive building into a complex of multiple individual volumes. "Y" and "V" shaped floor plans along the landscape side extend view interfaces. Compressing the building depth optimizes internal daylighting and ventilation, reduces the visual "oppression" a large volume might impose on the city, and creates a rich, varied mountain-ridge form.
Transitioning Nature and the City, the Communalization of Park Gardens
The project addresses dual boundaries facing nature and the city. By opening towards the city on the north and west sides, creating internal green corridors, and employing elevated ground floors, an open and coherent circulation route is formed. City dwellers can traverse the complex directly to the lakeside, facilitating two-way penetration between nature and the city.
Furthermore, the "Y" and "V" shaped buildings enclose several courtyards facing Xifengyang Park, with roof gardens arranged at different levels. The complex becomes a transitional space where natural landscape permeates the city and a public garden for the city.
Modern Materials "Sculpt" the Building Form, Technology Skillfully Integrated into Nature
The building massing, conceived as "flowing landscape," simulates natural mountain forms unfolding towards the water, creating an embracing landscape pattern with Xifengyang Park. It also forms layered setbacks at the top to optimize spatial layout. Parts of the façade feature a "striated" texture mimicking mountain rock.
Modern materials "sculpt the mountain" and optimize space usage. Silver horizontal metal eaves mimic mountain silhouettes, create public shaded spaces, and provide effective sunshading. The glass-and-metal curtain wall balances solid and void. The silver metal material not only conveys a technological aesthetic but also reflects the natural environment onto the building, achieving another form of symbiosis between nature and technology.
Ultra-Long Seamless Structural Challenges, Concerted Futuristic Shaping
The building form is complex and irregular, with the main building's single plane reaching up to 190m in length. The sky corridor, housing the hotel's sky lobby and restaurant, is positioned high, connecting main towers that differ in layout, number of stories, form, and dynamic characteristics, posing extreme structural design challenges.
Using a traditional "weak connection" approach (with structural joints at one end of the corridor to allow movement during earthquakes or high winds) would require corresponding expansion joints in the curtain wall. Given the corridor's high position, these joints would be wide and disrupt the façade's aesthetics. Therefore, a "strong connection" approach was adopted, using an ultra-long seamless structure to rigidly connect the corridor to the main towers, minimizing the impact of structural joints on the building's plan and elevation.
To reduce mutual influence between the two towers, ensure the corridor's visual transparency, and achieve the intended futuristic, floating sensation, a "high strength, low stiffness" structural design strategy was employed. This means high structural strength meets the corridor's load-bearing requirements without increasing its stiffness, avoiding full-story trusses and eliminating vertical members between floors. The floating cloud restaurant and the "mountain-shaped" towers together, in their contrast of "light" and "heavy," evoke the意境 of "floating clouds emerging from mountain peaks."
Three years have passed since the structural topping-out. China Energy Conservation · Taihu First Tower has become a new urban landmark in Huzhou with its distinctive form.
