03
Constructed with a unique bent A-frame design.
04
Integrates biodegradable materials into the facade.
05
Employs graphene for enhanced structural and filtration performance.
The Breathing Tower is an innovative architectural project designed to combat urban air pollution, specifically in regions like China that are significantly affected by deteriorating air quality. The project combines residential, commercial, and ecological functions within a single structure, centered around the principle of environmental sustainability. The design integrates advanced technologies aimed at air purification while providing necessary living and working spaces.

This architectural design features a sleek, organic form that tapers toward the top, resembling natural plant structures. It is constructed using a variety of materials that enhance its functionality and sustainability, including photocatalytic titanium dioxide to purify air, graphene for strength and filtration, and concrete for structural integrity. The incorporation of biodegradable materials in the facade and the use of water filtration systems underscore the project's commitment to reducing environmental burden.

Unique Design Approaches

The Breathing Tower distinguishes itself from conventional skyscrapers through its integrative approach to architecture and ecology. Unlike typical urban buildings that primarily focus on maximizing usable space, this project emphasizes its role as a living entity that interacts with its urban environment. The air purification system utilizes photocatalytic reactions to convert pollutants into harmless compounds, engaging in a sophisticated process that serves to improve overall air quality. It is estimated that the tower can process approximately 3.8 million cubic meters of air daily, significantly aiding in urban sustainability efforts.

Inside, the Breathing Tower includes dedicated spaces for urban gardening and hydroponics, promoting biodiversity and sustainable food production. The ecosystem that the tower supports benefits both residents and the environment, creating a harmonious relationship between architecture and nature.

Integration of Environmental Technologies

Water management within the Breathing Tower is optimized for sustainability. A comprehensive rainwater collection and filtration system reduces reliance on municipal water supplies while serving the building's internal agricultural systems. The combination of algae and plant life within the structure further enhances its ability to recycle carbon and generate oxygen, illustrating a commitment to creating a self-sustaining habitat.

The architectural design fosters a biophilic environment, encouraging interaction with nature and supporting human health and well-being. This thoughtful integration of sustainable practices within an urban context invites a reevaluation of what modern architecture can achieve.

For further insights into the detailed architectural plans, sections, and designs of the Breathing Tower, we encourage you to explore the project presentation. Understanding these architectural ideas can provide deeper knowledge of how this project innovatively addresses pressing urban issues while setting a precedent for future developments in architectural design.

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.
