Algae-Infused Timber Structure Enhancing Urban Air Quality

Project in-detail

Incorporating a dynamic algae filtration system within a timber structure, this design aims to significantly improve urban air quality while providing a self-sufficient environment for its occupants.
5 key facts about this project
01
Algae systems integrated into the facade actively filter polluted air.
02
Timber used in construction serves as both structural support and carbon storage.
03
Vertical farming spaces allow for local food production within the building.
04
Designed to adapt as emergency shelters during air quality crises.
05
Trees incorporated serve as both carbon sequesters and future building materials.

Algaescape is located in Delhi, addressing the serious issue of air pollution in one of the most polluted urban areas in the world. The design focuses on creating a multifunctional and self-sufficient structure that promotes sustainability and enhances air quality for its users. Central to the concept is the integration of natural systems, particularly algae, which work in partnership with the building to improve living conditions and support the local environment.

Natural Filtration Systems

A key feature of Algaescape is the use of algae as a natural filtration system embedded in the building's facade. This innovative approach captures carbon dioxide from the polluted air. Fans draw in the surrounding air, which then moves through hidden tubes where the algae are located. Here, the algae can effectively use carbon dioxide in a process that produces oxygen. This design is an effective response to the challenges posed by air quality, providing a healthier environment for those who inhabit the building.

Sustainable Materials

In addition to algae, timber is used in the construction as a secondary means of capturing carbon. This material not only supports the structure but also locks away carbon for the long term. The design includes various trees that absorb carbon during their lifecycle. When these trees reach the end of their lives, they can be sustainably harvested and used as building materials for future projects. This idea promotes a circular economy, incorporating recycling directly into the building's framework.

Self-Sufficiency and Adaptability

Algaescape is designed to be self-sufficient, with the goal of providing clean air, food, water, and energy for its occupants. This reduces the building's need for outside resources. The structure is also adaptable; different spaces can be repurposed to offer shelter during emergencies, such as smoke outbreaks or hazardous smog. Such flexibility ensures the design can effectively respond to environmental challenges in a city that frequently faces air quality issues.

The incorporation of vertical farming enhances the building's function by enabling food production close to urban residents. This relationship with nature supports sustainable food sourcing while also improving air quality through added plant life. Overall, the design represents a meaningful connection between built environments and natural ecosystems.

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.
