Carbon Wood Structures Embracing Breath Spaces in Urban Ecosystems

Project in-detail

Utilizing carbon wood and integrated breath spaces, the design enhances urban ecosystems while contributing to improved air quality in a densely populated area.
5 key facts about this project
01
Utilizes carbon wood from trees that can no longer sequester carbon.
02
Incorporates breath spaces designed specifically for urban air purification.
03
Promotes a sustainable cycle by replanting young trees where carbon wood is processed.
04
Strategically integrates greenery to enhance the urban microclimate.
05
Connects community use with ecological restoration in densely populated areas.

The project is located in the southern region of Seoul, South Korea, particularly in Gangnam. It tackles key issues related to pollution and carbon emissions that are common in urban areas. The design aims to respond to the environmental challenges posed by the numerous concrete structures in the region. It introduces ideas that focus on sustainability and improving the urban environment, aiming to create a healthier setting for residents.

Conceptual Framework

At the center of the design are two main ideas: 'Carbon Wood' and 'Breath Space.' The 'Carbon Wood' concept involves using trees that can no longer absorb carbon. These trees are converted into timber for construction, reducing reliance on traditional timber sources. This practice not only helps the environment but also allows for the replanting of young trees in the areas where the Carbon Wood is processed. Such a cycle seeks to achieve balance and sustainability within the building process.



Air Quality Enhancement

In addition to 'Carbon Wood,' the 'Breath Space' idea introduces features aimed at improving air quality in dense urban settings. Plants and air purification systems are integrated into the design, actively working to counteract urban pollution. These spaces are designed to serve as havens, capturing harmful air pollutants while contributing positively to the surrounding environment. This focus on air quality is especially important in areas like Gangnam, where population density is high.



Spatial Arrangement and Interaction

The layout promotes accessibility and encourages social connections among people. Careful placement and organization of spaces enhance the effectiveness of both 'Carbon Wood' and 'Breath Space.' This thoughtful design allows for an interaction between the built environment and nature. Breath Spaces are specifically made to filter and improve air quality, offering residents a refreshing experience amidst the concrete surroundings.



Historical Context and Transformation

The project acknowledges the historical changes in Gangnam, which has evolved from a landscape rich in forests and rivers to a congested urban area over the last sixty years. This background influences the design, emphasizing the importance of bringing back ecological elements into city life. The architecture reflects this transition, aiming to shift urban development to focus more on sustainability.



The final design details illustrate a careful mix of built forms and nature. Structures rise from the ground, allowing space for greenery to flourish, making them an integral part of the urban ecosystem.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
