Soft Infrastructure
Community-built resilient erosion control
Soft Infrastructure explores how common reed can be used as a sustainable material for erosion control. Conventional methods rely on synthetic materials that disrupt ecosystems and cultural landscapes. This project repurposes reed grown in eutrophic waters into grids that stabilise soil, by protecting it from rain and wind while allowing native plants to recover as the reed decomposes. Community engagement is central, reflecting the Finnish talkoot tradition—collective labor for the common good.

As weather conditions become more extreme, soil erosion accelerates due to prolonged droughts and increasingly intense rainfall. Agricultural practices leave soil exposed and vulnerable, intensifying this problem. Rainwater also washes nutrients from fields into nearby water bodies, causing overgrowth of species like the common reed.
Soft Infrastructure explores how invasive species in aquatic ecosystems can be repurposed as raw material for erosion management structures. Conventional erosion management methods usually rely on synthetic materials, which are harmful for the environment. Our proposal offers an alternative using communal and ecological knowledge to create a local sustainable solution.
Our project draws inspiration from traditional methods using natural materials like brushwood to construct large-scale structures. One notable example is the fascine mattress, developed in the Netherlands to protect riverbeds. We are inspired by how these abundant, inexpensive materials can be transformed into resilient structures that withstand natural forces.
Soft Infrastructure focuses on the common reed (Phragmites australis), which thrives in entrophic waters such as the Baltic Sea, as its root systems filters efficiently nutrients. If left unharvested, the reed decays and releases trapped nutrients back into the water, continuing the harmful cycle.
We aim to assemble reed bundles near shorelines and transport them to erosion-prone hillsides, where they are arranged into a grid structure to protect the ground. This temporary solution allows local flora to recover, eventually taking over the role of stabilising the ground.
The assembly requires manual labor, and we envision engaging local communities. The Finnish term “talkoot” represents community gatherings for the common good, central to our approach. This project also draws inspiration from traditional crafts like weaving and basketry, which we aim to adapt in a new context.

Soft Infrastructure explores how the common reed (Phragmites australis), an abundant and often invasive species, can be repurposed as a sustainable material for erosion management. Conventional methods often rely on synthetic, non-biodegradable materials that disrupt ecosystems and cultural landscapes. This project proposes an alternative, combining ecological and communal knowledge to create a locally sourced solution.
Inspired by traditional techniques like the Dutch fascine mattress, the project reimagines historical practices of using natural materials for large-scale surface erosion prevention. The common reed, thriving in eutrophic environments such as the Baltic Sea, serves a dual purpose: mitigating eutrophication by removing excess nutrients and providing material for erosion control.
Reed grids act as temporary barriers, protecting soil from heavy rain and wind while enabling local vegetation to recover. This method aligns with broader trends in landscape architecture and ecological design, which emphasise adaptive, nature-based solutions over rigid, industrial approaches. By working with organic materials that decompose over time, the project supports a regenerative model where infrastructure facilitates ecological restoration rather than imposing a permanent, disruptive presence.
The concept emphasises community engagement, reflecting Finland’s tradition of talkoot—collective labor for the common good—and applies traditional craft processes to modern infrastructure. Beyond its environmental benefits, the project fosters a participatory approach to climate adaptation, empowering local communities to take an active role in restoring and maintaining their surroundings.

Currently, Soft Infrastructure is being developed as an installation for the 2025 Venice Architecture Biennale. The next step of this process, is to construct a full-scale prototype within the next year, to test the and measure the impact of the concept.
The project has been developed in collaboration with Arcada University of Applied Sciences and the John Nurminen Foundation, an organization specializing in Baltic Sea conservation. Their involvement has been valuable in providing insights into the material, its sourcing, and potential future directions for the project.
The engagement of different stakeholders at local, regional, and national levels is crucial to the project’s success. We envision that local municipalities can play a key role in organising harvests and community workshops, while national environmental agencies can help integrate the method into broader conservation strategies. By involving institutions across multiple levels, the project ensures that its impact extends beyond a single intervention.

The project combines expertise from multiple disciplines. As an architect and a designer, our backgrounds bridge sustainability, DIY methods, and community-driven processes. Our collaboration has been crucial in shaping the project’s spatial, material, and participatory elements. We are both interested in craftmaship, which has been guiding point the project.
With the guidance of the John Nurminen Foundation and Arcada University, we have incorporated knowledge from biology and material science, refining the method from both ecological and technical perspectives. Additionally, we have applied craft-based approaches at a larger scale, to a textile-like architectural structure.

Soft Infrastructure empowers communities by offering a direct, tangible way to care for their local environment. The project encourages people to organise themselves around a shared goal, drawing on historical forms of collective labor like talkoot. Traditionally, talkoot involved people coming together to help with harvests, construction, or other labor-intensive tasks for the common good. Today, this communal ethic can be applied to environmental restoration.
In practice, the project envisions local groups forming to harvest reed and assemble erosion control structures. This not only strengthens community ties but also provides a sense of empowerment—especially in times of ecological uncertainty—by allowing people to take meaningful action in their immediate surroundings.
By involving local citizens, municipalities, and environmental organisations, the project ensures that knowledge is transferred across different levels of society. Rather than relying on external experts to implement solutions, Soft Infrastructure enables people to take charge of their landscapes, fostering long-term stewardship.

Currently we are developing the structure as a installation for the 2025 Archintectural Biennal in Venice. Hoewever, we are planing on making a full scale prototype for testing the concept further. We are collaborating with John Nurminen Foundation, who is a specialist when it comes to the baltic sea. They have shown an interest to support us in further development of the concept.

Conventional erosion control relies on synthetic geotextiles, plastic netting, and heavy infrastructure that often disrupts ecosystems. Soft Infrastructure takes a different approach by utilising an abundant, natural material and employing a craft-based assembly method.
This project rethinks what infrastructure can be and who can produce it. Instead of relying on industrial manufacturing, it introduces a decentralised, hands-on process where communities play an active role in construction. This challenges the conventional notion that environmental restoration must be a top-down, expert driven projects. We see the specialists as guides/facilitors of the restoration.
We believe that our advantage lies in our creativity and diverse backgrounds, coming from architecture and design. This different perspective helps us come up with new types of solutions in an engineering-heavy field.

Soft Infrastructure was developed with the principle of working with what is already available. The project emerged from an investigation into how common reed—an abundant yet nowadays underutilised material—could be repurposed for ecological benefit.
The method is inspired by historical practices, particularly the Dutch use of fascine mattresses for stabilising riverbeds. By adapting this concept to modern environmental challenges, the project combines traditional knowledge with contemporary sustainability concerns.
Prototyping and testing are integral to the approach. The project is currently in a research and development phase, with plans for a full-scale test to measure effectiveness and refine construction techniques.

The principles behind Soft Infrastructure are highly transferable, as the common reed and land erosion are equally a cosmopolitan species and problem. The method could be adapted to different climates and ecosystems by modifying harvesting techniques and structural details.
Beyond erosion control, the bundled reed technique has the potential for other applications. One potential area of use is the development of maritime oil barriers, where reed bundles could be used both as floating elements and absorbent material.
At its core, the project is about empowering people through collective action. By encouraging locally organised restoration efforts, Soft Infrastructure presents a scalable model for citizen-led environmental intervention.

We think that dealing with problems of the changing climate has to be countered on societal levels. Local solutions is the most direct form of action, and can be applied where the people sees it being needed the most. As the reed material can be sourced from a variety of costal areas, the material used for the infrastructure is sourced locally or as locally as possible.
Eutrophication of water bodies, caused by farming and industry, fuels the growth of plants like common reed and algae, which, when breaking down, consume oxygen and burden local ecosystems. By using reed as raw material for our project, we are helping to reduce excess nutrients in these environments and support a healthier ecosystem.

In the coming year, the focus will be on:
* Producing and presenting the installation for the Venice Architecture Biennale 2025.
* Constructing a full-scale prototype to test the method’s effectiveness.
* Network and finding suitable organisations to partner with.
* Securing funding to support field trials and to develop the project.
* Exploring possible pathways for integrating the technique into broader environmental policies and conservation initiatives.
* Start building a platform/ guide.
If the prototype proves to be successful, the next step would be launching a pilot project in collaboration with municipalities and organisations, with the long-term goal of making this method widely accessible.
