SPATIAL
Time Tower (2024) | A combined sculpture, viewing tower and exhibition space in the garden of Sonneveld House, on the occasion of 100 years Museumpark Rotterdam, bringing together the layers of past, present and future and making them spatially and sensorially experienceable. photo by Ossip van Duivenbode

Fragment Encounter Iced Sound. Model Fest. Barcelona (2023) | A transportable spatial and sound installation brought to three different places in the city creating a ’sonic route’, inviting passers-by to engage with the topic and listen to the compositions.

RESEARCH – CURATORIAL
Evidence of the Absent (2019) | A year of interdisciplinary research and dialogue about the city in transformation, as Architects in Residence and on-site, through the (re)interpretation of real-scale architectural representations used to communicate future plans within the present context of the city.
Urban Transformation as Event - rr-dialogues (2018) | One-year experimental ‘rotative research’ project in various cities, with over thirty invited contributors from different (artistic) disciplines, on both content and method. A continuous expansion of perspectives on the same topic, as well as an experimental publishing project.
The Image of Promises, Simultaneity in Cities (2017) | In this fast-paced moment of transformations and homogenisation taking place in the world, we felt it was urgent to forge another consciousness about the impact of this rapid process of transformation on our cities, that affects how we know them, both their physical and cultural presence.
Space in-between London Festival of Architecture (2020) | Interactive exhibition & roundtable, following up and building on a one-year residency in Zürich in 2019. On the space of potentiality in the borderlands between present and future, and the importance of physical experience and imagination in architecture.
Conditions for Growth - Ministerie van Maak International Architecture Biennale Rotterdam (2022) | A proposal aimed at preserving, renewing and diversifying the landscape and (re)valorising the existing built environment - with a step-by-step densification strategy and six ‘conditions for growth’ for the town of Margraten (NL) and the surrounding area.
The Artist Studio Revisited. | Research on the transformation of artist studios, from the first forms we know up until the present. On the relationship between the (art)work and its place of creation – the interaction between developments in the visual and performing arts on the spatial form of the studio and on the studio as a concept.
Arts & Architecture Magazine + the Case Study House Program | Archival Research at the Getty Research Institute (Los Angeles) and site visits.
EDUCATION – WORKSHOPS
Along the Line (2017) | On the occasion of 150 years since the Jura water corrections, focussing on the transformation process of the waterfront in Yverdon-les-Bains (CH). By projecting the former (past) shoreline within the present, and walking along this ‘line’ together with the city’s residents, we analysed changes and reflected on opportunities for the future.
Exchange in Practice 2024 Nieuwe Instituut and Flanders Architecture Institute | For the fourth edition, seventeen promising designers from the Netherlands and Flanders/Brussels were selected to focus on co-creation in the reconversion project of the former Stuivenberg Hospital, located in the densely populated Seefhoek in Antwerp.
Intercultural Bench IDW2020 University of Antwerp | With a 35-meter long bench, we occupied a piece of public space in Antwerpen Luchtbal and claimed for more dynamic and interactive common spaces outside.
Learning from Venice – anticipating a constantly changing landscape Rotterdam Academy of Architecture (2021-22) | Making the future flooding of inner-city rivers visible in the present, to architecturally and culturally revisit public space and the value and meaning of urban elements by which it is formed.
Path of Play IDW2022 University of Antwerp | A sequence of interactive elementary structures – tactile transformable artefacts – that allowed students and residents to generate new places. Suggesting space through minimal means, infusing them with personal and cultural values, creating new common meaning.
Architectural Positions TU Delft (2021) | Imagining an entirely different development for a currently ‘vacant’ plot within the area of M4H in Rotterdam – one that is not market-driven, but that answers to local, national and even global questions, and that carefully considers all the site-specific conditions.
New Constellations IDW2021 | Creating ephemeral and imaginary spaces and trajectories to give new value and meaning to the ground floor (public) space of one of the Langblokken – 200 meters long – and to evoke new uses.
WRITING – PUBLICATIONS
Designing for the Endgame(IABR & nai010 publishers (2023) | Publication on designing in times of climate crisis, including an account of the 9th International Architecture Biennale Rotterdam, results of the research-by-design in the IABR–Ateliers, and a series of reflective essays. photo by Rick Keus

What role can architecture play mediating between present and future, and what is the potential of this ‘space in-between’? graphic design by Sara Sidler
rotative research: Urban Transfromation as Event | Collection of the two acts, all contributions ánd correspondance of the project Urban Transformation as Event, as part of the research method ‘rotative research’
Imagine the Volume (2019) | How much do we need to imagine something? Using only the actions of removing and adding, the set of drawings imagines a new volume within a given contour. The only rule was that the whole should at any time remain recognisable.
Tracing Postmodernities Architecture Foundation (2022) | With rotative studio we were asked six questions by curator Job Floris. He asked a number of younger Dutch and British practices to discuss their relationship to the postmodern discourse.
