Eternal-AX06: A 120-Storey Skyscraper That Breathes, Filters, and Regenerates the City

What if a skyscraper could inhale polluted air at its base, filter it through bio-chambers and green walls, and exhale clean air from its crown? Eternal-AX06 takes that question literally, proposing a 120-storey tower whose kinetic façade expands and contracts in response to heat and wind, whose structure doubles as an atmospheric purification system, and whose energy needs are met by the very forces acting on its skin. It is less a building than an urban organism, one designed to participate in the ecological health of its city rather than simply occupy space within it.

Designed by Gourab Das, the project was entered in the Alter competition as a People's Choice Award entry. Sited on an urban coastline, the tower rises from a base of reflective water surfaces and tidal pools, integrating wind, water, and solar energy systems into both its structural frame and its shifting façade. The result is a design that treats sustainability not as a constraint to satisfy but as a generative principle that shapes every architectural decision.

A Façade That Moves with the Weather

The defining feature of Eternal-AX06 is its kinetic façade system: a high-performance, solar-responsive shell embedded with mechanical and environmental sensors. The panels expand and contract according to shifting heat and wind conditions, optimizing natural ventilation and daylight penetration in real time. The tower never looks the same twice. Its geometry is in constant flux, giving the structure a living quality that distinguishes it from the static curtain walls of conventional supertalls.

The sectional collage drawing reveals how this system works in tandem with the tower's cooling infrastructure. Energy-harvesting panels double as wind turbines and solar receptors, meaning every façade movement contributes to renewable energy generation. The annotated diagram also introduces a striking layer of cultural narrative: mythological figures appear alongside engineering annotations, a deliberate fusion of spiritual symbolism with technical ambition that positions the project as both a pragmatic proposal and an artistic statement.

The Tower as Urban Lung

The vertical filtration system is where Eternal-AX06 makes its boldest claim. Vacuum suction at the base draws polluted city air into the structure, where it passes through multiple layers of bio-filtration chambers, green walls, and water pools. Dust and toxins are captured and filtered naturally before purified air is released from the top. The skyscraper becomes, in effect, a vertical lung for its district, processing the atmosphere at an architectural scale.

The exploded axonometric diagram clarifies the tower's programmatic organization. Residential blocks and a commercial podium are separated and stacked, connected through public plazas and kinetic canopies that extend outward like architectural roots. These canopy zones house retail and social spaces, blurring the boundary between tower and ground plane. The red and white color coding makes the functional hierarchy legible at a glance: living above, commerce and community below, with the filtration infrastructure threaded through the entire section.

A Twisted Diagrid Against the Skyline

Seen from street level and across the surrounding cityscape, the tower's perforated, twisted diagrid façade asserts itself against the orthogonal grid of neighboring high-rises. Under stormy evening skies, the perforations catch shifting light in a way that reinforces the building's kinetic identity. From below, with rain falling and a figure holding an umbrella in the foreground, the scale becomes visceral. The twist of the structural skin is legible even at close range, giving pedestrians a sense of the tower's rotational energy.

These street-level views also hint at the microclimate strategy at the base. Pools and reflective water surfaces moderate temperatures around the tower's entry zones, cooling the air drawn into the purification system and creating a sensory connection to the nearby ocean. A helipad crowns the tower, serving as both a transportation hub and an observation platform, completing the vertical journey from tidal pool to sky.

Slender Form, Coastal Presence

At dusk, the tower's slender profile and twisted diagrid façade read as a single, luminous gesture against the waterfront skyline. The proportions are remarkably delicate for a 120-storey structure, suggesting that the kinetic façade and structural system work together to distribute loads efficiently while maintaining visual lightness. The coastal siting is not incidental: proximity to water informs the tower's energy and cooling strategies, and its silhouette becomes a landmark that mediates between the density of the city and the openness of the harbor.

Why This Project Matters

Eternal-AX06 operates in a register that many supertall proposals avoid: it asks the skyscraper to give something back. The idea of a building that actively filters urban air, generates its own energy through façade movement, and moderates its microclimate through water systems at its base is not merely aspirational. It reframes the tall building as a piece of environmental infrastructure, not an isolated monument. The cultural layer, with its mythological imagery woven into the technical drawings, adds a dimension of meaning that pure engineering proposals often lack.

Gourab Das has proposed what he calls regenerative architecture: a system that restores ecological balance through interaction rather than simply reducing harm. Whether or not every technical claim survives scrutiny at a detailed engineering level, the ambition here is instructive. It suggests that the next generation of supertall design should be measured not only by height, structural innovation, or commercial viability, but by its capacity to participate in the health of the city it inhabits.
