Architecture inspired by nature, powered by technology
Rising 89 metres in Fuzhou’s Jin’an District, the IGG Tianmeng Tower reimagines the city’s iconic banyan tree as a 50,000-square-metre office building, a living symbol of growth, resilience and innovation.
Merging sustainability and digital culture, the project creates a next-generation workplace where architecture and interiors work in concert: from the organic, cantilevered form that extends Fuzhou’s green canopy skyward, to immersive interior environments that translate game logic into spatial experience.

Architecture: the banyan tree reimagined
Inspired by Fuzhou’s famed banyan tree, the tower’s organic silhouette, vertical atrium and layered terraces embody the spirit of this local icon, rooted in nature, yet reaching towards the future. Located at the crossroads of Fuguang Road and Fuxin Road, the design harmonises with Fuzhou’s cultural identity as the “City of Banyan Trees” whilst catalysing development within a growing digital economic hub. Layered terraces extend the green urban canopy, whilst public plazas and shaded walkways create an interface between the building and its neighbourhood.
The banyan’s anatomy is translated into architectural form: a central structural trunk organises vertical circulation, branch-like cantilevers create flexible office floors, and a spiralling atrium of aerial roots visually and socially connects the interior. Terraces and rooftop gardens offer restorative outdoor spaces, whilst the layered façade filters sunlight and evokes organic textures. From the “Gamers Heart” central hub to sky lounges and event spaces, the tower merges art, technology and nature to cultivate innovation and engagement.
The tower’s environmental strategy integrates passive design, material efficiency and ecological connectivity. Its breathable façade and external shading reduce mechanical cooling loads whilst maximising daylight and views. Natural ventilation, rooftop gardens and porous ground-level landscaping collectively enhance microclimate performance and urban biodiversity. Structurally, a minimised ground footprint and centralised core optimise both stability and airflow, ensuring efficiency in construction and operation. Together, these strategies transform the building into a “living system,” a sustainable prototype aligned with IGG’s corporate responsibility and Fuzhou’s green urban vision.
Interiors: From reality to surreality
Guided by IGG’s ethos “Innovators at Work, Gamers at Heart,” the interior is conceived as a continuously evolving spatial experience that integrates game culture, corporate identity and everyday work. The design translates game logic into spatial experience, resulting in an environment that is imaginative, unexpected and grounded in everyday use. Beyond representing a game company, the interiors embed IGG’s values of innovation, exploration and adventure, supporting creativity across the organisation.
The building becomes the Banyan Castle, an immersive game world where employees and visitors move through spaces that shift between reality and surreality. Natural references from Fujian, including banyan trees, caves and organic growth patterns, ground the narrative in local context, allowing imagination and place to coexist.
The interior is organised around a clear narrative sequence. The Welcome Portal (ground floor) forms the public interface through the sculptural Rabbit Hole, creating a strong sense of arrival through immersive circulation and integrated brand storytelling. The Heart of the Game anchors daily operations and collaboration across typical office floors (Levels 5–14), where structured layouts, soft colours and flexible furniture support focus whilst subtle moments of play reinforce the gaming mindset. The Sky Portal houses multipurpose, training and leisure spaces, whilst the Earth Portal accommodates dining and staff amenities, grounding the workplace in everyday wellbeing.
Layered throughout are immersive public experiences: a Level 2 children’s centre supporting learning through play with child-scale design; a Level 3 dining space reimagined as a Modern Babylon Garden to encourage social interaction; and a Level 4 multimedia centre, conceived as a Digital Temple, combining controlled light and quiet spaces for gaming culture, training and media production. Upper-level wellness and multipurpose spaces integrate fitness, leisure and future-oriented narratives, extending the experience beyond the workplace.
Impact and outcomes
The IGG Tianmeng Tower delivers measurable value across multiple scales. For IGG, it strengthens corporate identity as a global innovator, providing employees with inspiring, wellness-oriented environments that foster creativity and connection. For Fuzhou, the tower’s bold yet contextually grounded form enriches the skyline and exemplifies sustainable, human-centred design. By embedding IGG’s values of exploration, creativity and adventure into both architectural form and interior experience, the project transcends its role as a workplace, standing as a catalyst for Fuzhou’s evolution into a world-class, future-ready metropolis.

“We never saw this as just an office tower. It’s the physical embodiment of IGG’s culture, born from the context of Fuzhou itself. Our goal was to use advanced health and wellness principles to express their core commitment: to their team’s health, to the city’s fabric, and to responsible stewardship of our environment. That’s the real achievement here.”
