Prix de Rome 2026 shortlist

15.04.2026

We are very honoured to be shortlisted for Prix de Rome Architecture 2026!

In the coming months, we will develop our vision for "Slow Assembly". The results will be part of an exhibition in Nieuwe Instituut in Rotterdam at the end of the year.

From the jury report:

"Slow Assembly" rethinks the temporality of construction itself, proposing bioregional material-time as a non-negotiable counter-logic to the political acceleration of housing delivery in the Netherlands. [...] The jury found particular strength in the proposal’s concept of multiple temporalities: the idea that social-time, historical-time, adaptive-time and material-time each operate at different speeds, which a rigorous tectonic approach can hold together, rather than flattening them into a single delivery logic.

Lecture at the AHK

27.02.2026

Federica has been invited to give a lecture on our work and approach towards bioregionalism to students at the Amsterdam Academy of Architecture, as part of the urban design course “Regenerative City Growth x Degrowth of the Former Peat Colonies of Drenthe x Overijssel”, led by Giacomo Gallo (New Environments).

Bioregional Buffer Strips

01.12.2025

The first phase of our research together with Spacevalue into the cross-border Kempen region, between Noord-Brabant and the Province of Antwerp, is now complete. The report introduces bioregional buffer strips: productive landscapes that improve water quality through the cultivation of biobased building materials and create new regional value chains linking farming and construction.

South Korea trip

18.03.2024

Federica, together with Myriam López Rodero, has organised a Design Studio at the Academie van Bouwkunst Groningen about future cities, focused on Seoul. She is now leading a group of students on a trip to South Korea, where they will meet numerous local architects and experts, have a workshop with other students from Soongsil University and visit their project site. The trip is also an occasion to meet and exchange ideas with Professor Jungin Kim, a fierce proponent of the use of bio-based materials like wood, instead of concrete, for construction in Seoul.

Architectenpoule kick-off

05.02.2024

The Architectenpool Tilburg Business Parks has officially been launched. Together with Office KGDVS and &bogdan, we have been selected to work alongside Gemeente Tilburg and local entrepreneurs to develop new ideas for industrial areas in Tilburg. We kicked off the collaboration with a workshop and day trip to Brussels, to brainstorm and visit some of the best built examples of projects integrating production into the city.

Apline Ecotones

During a three-month residency at Fundaziun Nairs, Federica developed a research focused on the high alpine meadows—the fragile, interstitial zones situated between the forest edge and the rocky mountains. Unlike anthropogenic pastures, these meadows are naturally occurring ecosystems. Today, their rich biodiversity is under threat from climate change and the upward migration of the tree line ecotone.

Through a methodology of site walks, mapping, and a synthesis of objective and subjective observation, the project aimed to document these often-overlooked landscapes. Living within an "immersive bubble" allowed the Swiss landscape to transition from a backdrop to an active participant in the work. By prioritizing process over a fixed outcome, the project develops an engaged methodology to record the subtle and ever-changing frictions between the natural and man-made environments.

Forest (in) Transition

Forest (in) Transition reimagines Zlatica Park-Forest as a regenerative system within Podgorica’s green infrastructure. Situated at the geological threshold between karst foothills and the alluvial plain, the project adopts an ecotonal framework. By treating the park as a sequence of transitions—from forest core to urban edge—the design strengthens ecological connectivity and acts as a resilient climate buffer for the city.

The strategy counters the decline of the existing monoculture through three pillars: Living Soil, Inhabited Forest, and Microclimatic Design. We propose transitioning the site into a drought-tolerant mixed woodland, utilizing existing pines as a "nurse canopy" for new species like Macedonian oak and hop-hornbeam. Integrated rainwater harvesting transforms seasonal rainfall into a resource that sustains the forest and cools the microclimate during dry summers.

Social activity is woven into the forest through "Social Ecotones": a Cultural Axis, Sport Grounds, and Ecological Islands. Within these zones, architectural interventions act as "Microclimatic Devices" — hybrid structures combining social programming with water storage and cooling gardens.

Bio-regional Buffer Strips

The project explores how bio-based construction materials could be produced in the sandy region between Noord-Brabant and the Province of Antwerp, addressing urgent housing and urban development needs. It defines this cross-border area as a single bio-region, shaped by river valleys that connect Belgium and the Netherlands in ecological and cultural terms.

Through this lens, we have examined local farming practices and found that they exert strong pressures on water systems, contributing to the Netherlands having the lowest water quality levels in the EU. Recognizing this challenge alongside the growing demand for housing, we embraced a bioregional approach to the use of resources — working with natural systems and seeking to generate ecological and social benefits, rather than depletion — and defined the concept of bio-regional buffer strips. We envisioned these landscapes along waterways as areas where bio-based construction materials can be cultivated, while restoring soil and water quality through phytoremediation. Beyond their productive role, these strips act as climate-adaptation tools, managing floods and droughts, supporting biodiversity, strengthening local economies, and offering spaces for recreation.

By linking sustainable urban development to ecological restoration, the project demonstrates how healthy cities and resilient landscapes can be built together, rooted in the natural and cultural fabric of their region.

Grounds of Repair

In collaboration with Tim van den Burg (Bredase Bomen) and the Municipality of Breda, we are conducting research and a feasibility study for a new site for Bredase Bomen’s operations. This project explores the potential to expand the area into a multifunctional hub that supports diverse businesses, provides shared spaces and services, highlights circular materials, and incorporates public amenities accessible to all Breda residents. The vision is a layered redevelopment that integrates soil regeneration, landscape interventions, the cultivation and testing of bio-based materials, alongside dedicated educational and recreational zones.

Through hands-on research, we are mapping existing structures and materials suitable for reuse, analyzing material and activity flows within local companies, and identifying potential partners such as universities and businesses. A series of meetings and workshops supports the development of flexible scenarios that respond to different needs, scales, and phases of implementation.

The project aims to evolve into a built prototype— an innovative circular area that functions as both a community anchor and public hotspot throughout the long-term development of the ’t Zoet neighbourhood.

New Industrial: Tilburg

Commissioned by the Municipality of Tilburg as one of the selected teams within the Architectenspool, we have been conducting a series of studies on industrial sites in Loven and Kraaiven. The aim is to explore strategies for land-use optimization, densification, and climate adaptation, while also enhancing the architectural quality of industrial buildings.

Our approach centers on unlocking the hidden potential of these often-overlooked areas by:

· Encouraging shared use of functions among multiple businesses, including parking, communal and recreational facilities, logistics routing, and flexible storage.
· Designing mixed-use, multistory, and adaptable structures.
· Improving access to shared amenities and enhancing the spatial experience for both workers and visitors.
· Clarifying site layout by separating pedestrian and truck flows.
· Expanding green infrastructure to mitigate the urban heat island effect and improve rainwater buffering.
· Strengthening business identity and visibility.

Industrial areas are often pushed to the urban margins, yet they remain both vulnerable and underutilized. We see in them untapped potential to tackle climate issues, promote circular reuse, and advance spatial justice. By making these zones more efficient, compact, and climate-adaptive, we can better integrate them into the urban fabric and transform them into vital, future-proof parts of our cities.

Strata-scapes

"Strata-scapes" is a transformative strategy aimed at converting a former industrial and now vacant site into fertile grounds for pioneering landscapes and the experimentation with bio-based materials.

The project proposes a new way of urban development, building upon existing foundations and embracing traces of its spontaneous nature. To initiate the development process, we introduce Basic Infrastructures addressing essential technical and social needs. We combine them with Testing Grounds—areas for experimentation, and cultivation of biomaterials. Finally we complete them with Biobased Infills - architecture and structures made from material produced on-site.

In our vision, 't Zoet becomes a spatial laboratory: its architecture is a living assemblage that can evolve over time. The nurturing of a living environment is embedded not only in the design of its spatial layout and maintenance, but also in the conceptualisation, regeneration, production, and construction of its components.

Productive Commons

“Productive Commons” is a vision for a series of temporary interventions at the intersection of living and working, integrating circular and modular structures and regenerative landscapes. The structures draw inspiration from M4H's industrial heritage, weaving past narratives with future aspirations. They serve as flexible platforms, fostering productivity beyond economic gains, nurturing local ecosystems, and supporting communal activities.

Each of the interventions links to existing productive activities, offering support and resources - clean water, soil, material storage and shelter. All of them are modular and easy to assemble, disassemble and modify - in order to be expanded, moved or removed over time with the help of a local community. Proposed structures are supported by a landscape strategy that gradually makes the space safe, habitable, and attractive for new communities of people, plants, and animals.

The project was part of the exhibition HOE WILLEN WIJ WERKEN M4H 2030 (2022, KeileZaal, Rotterdam), organized by KeileCollectief, and was made possible by the Fleur Groenendijk Foundation. It was also exhibited as part of Rotterdam Architectuur Maand ‘24.

methods

Słodka x Zatta is a multidisciplinary design practice operating at the intersection of regional strategies, multi-stakeholder research, urban design, and local prototyping. Our methodology is grounded in deep site analysis, re-evaluating overlooked qualities and maximizing existing resources through adaptive reuse and climate-responsive design.

We reject the traditional dichotomy between “built” and ʼnatural” environments, instead understanding each site as an assemblage of material flows, cultural narratives, and interspecies relationships. Our aim is to develop proposals that combine environmental repair with high-quality social infrastructure.

Our practice is structured around three core themes: Bioregionalism, Circular Metabolism, and Climate Adaptation. These themes are translated through multi-scalar research and design, where long-term frameworks evolve into tangible, site-specific interventions and prototypes.

Our work goes beyond the design of static spaces to address the architecture of processes, systems, and networks. By collaborating with municipalities, water boards, and local industries, we engage complex societal challenges while advocating for shared environments that are resilient, dynamic, and socially just.
