Cross-Laminated Timber Structure Integrating Air Purification and Vertical Gardens

Project in-detail

Combining cross-laminated timber and titanium, this towering structure not only enhances urban landscapes with its verdant vertical gardens but also serves as a community-centric hub focused on air purification and collective well-being.
5 key facts about this project
01
Utilizes titanium dioxide in the facade for enhanced air pollutant neutralization.
02
Incorporates vertical gardens to promote biodiversity and improve air quality.
03
Features a unique cross-laminated timber construction that reduces carbon footprint.
04
Design emphasizes community-oriented spaces, facilitating social engagement.
05
Integrates green roofs that provide recreational areas while enhancing insulation.
The Smog Free Tower is an innovative architectural project located along the Han River in Seoul, South Korea. This design embodies a thoughtful response to the pressing issue of air pollution, particularly the fine dust that significantly affects urban populations. The structure stands 103 meters tall and 54 meters wide, representing a blend of functionality and an enhanced public realm, aimed at improving the community’s quality of life.

Central to the project is its dual function as both a smog filtration system and a social hub. The architectural design features two intertwining elliptical forms that are carefully crafted to symbolize interconnectedness and harmony with the surrounding environment. This organic shape not only distinguishes the tower from more traditional structures but also enhances its visual appeal against the urban skyline. The design is deliberate, with a focus on fostering community engagement through accessible spaces that promote interaction among residents and visitors.

The internal layout is meticulously organized across forty floors, integrating various public amenities that cater to both work and leisure. The first three levels of the tower are designed as communal spaces, encouraging social activities and a sense of belonging. As one ascends through the building, spaces transition to offices and serviced apartments, demonstrating an efficient use of vertical space while ensuring that residents enjoy enhanced views of the river and cityscape.

Materiality plays a crucial role in the design of the Smog Free Tower. A significant component of the exterior is titanium dioxide, a material that aids in the neutralization of airborne pollutants. This innovative element reacts with ultraviolet light to transform harmful substances into less toxic components, emphasizing the building's role in air purification. The use of this material not only enhances the tower's environmental credentials but also minimizes maintenance needs, given its self-cleaning properties.

Another key material is cross-laminated timber, which contributes to the tower's structural integrity while being lightweight and environmentally sustainable. This choice aligns with contemporary architectural trends prioritizing eco-friendly practices. Cross-laminated timber provides excellent thermal insulation and reduces the overall carbon footprint of the structure, highlighting the commitment to sustainability inherent in the project. Compress laminating process further bolsters structural performance while maintaining these ecological principles.

Unique design approaches in this project include an emphasis on creating an urban ecosystem. The integration of green roofs and vertical gardens promotes biodiversity and provides essential green spaces within the metropolitan environment. These features not only enhance the aesthetic qualities of the tower but also contribute positively to the well-being of its occupants, offering areas for leisure and relaxation in an otherwise bustling urban landscape.

The Smog Free Tower reflects a vision that goes beyond mere architecture; it represents a commitment to addressing the significant challenges faced by cities plagued by pollution. By combining advanced building technologies with community-focused design, the tower serves as a vital asset in enhancing urban life while promoting environmental stewardship.

For those interested in delving deeper into the details of this project, exploring the architectural plans, sections, designs, and ideas will offer valuable insights into the intricacies and thoughtful considerations underpinning the Smog Free Tower. This exploration will reveal the full scope of how architectural innovation can play a pivotal role in urban sustainability.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
