How can existing buildings be transformed and developed instead of being demolished and replaced with new construction? Transformation – RE:purpose is a practice-based research project that aims to contribute to innovative policy development. The project is a collaboration between ArkDes, Boverket, Riksantikvarieämbetet and Fastighetsägarna Sverige.
To reduce climate impact and the extraction of natural resources, the construction sector needs to transition towards more resource-efficient systems. Interest in circular economy, transformation and sustainable management has increased, but practical implementation is still at an early stage.
Through knowledge production and speculative design, the research project Transformation – RE:purpose explores possible ways to support the transition within the construction and real estate sectors towards more sustainable management and transformation of existing buildings. Practice-based research that brings together theory and practice is an important tool for achieving fundamental changes in attitudes and methods within the built environment sector and for contributing to national and global sustainability goals.
Through an open call, three interdisciplinary teams were selected to work with one building each: Turitzhuset in Bagaregården, Gothenburg, Kordahusen in Alviks strand, Stockholm, and Förvaltningshuset at Umeå University campus.
Proposals for the transformation and management of three properties
During 2025, the teams developed transformation and management proposals to highlight barriers and challenges related to transformation, but also the opportunities and values embedded in the existing built environment. Each team presents its work in an individual report, including proposals for policy changes aimed at reducing barriers and increasing incentives for transformation.

Turitzhuset in Bagaregården, Gothenburg
The team Nya värden i det gamla explored how Turitzhuset in Gothenburg can be developed and managed by highlighting architectural, climatic and cultural heritage values in the early stages of urban development.
The work was based on a critique of how the value of buildings is often reduced to technical and economic parameters. Instead, the team approached history as an active resource and emphasised the architect’s role in understanding and communicating the potential of existing buildings.
Through archival research and site analysis, the team mapped the transformation history of Turitzhuset, from its construction to the present day. The studies showed how previous alterations had affected spatial relationships, lighting conditions and movement patterns. Several of the building’s current challenges could be linked to changes made to the original structure.
Based on these studies, the team developed a transformation proposal in which existing qualities are reactivated and clarified. By reopening connections, restoring entrances and working with the building’s existing structure, the proposal enables a multifunctional use with housing, workplaces and shared spaces.
The work highlights the importance of integrating architectural analysis early in development processes and of broadening decision-making beyond economic parameters. It also demonstrates how existing environments can evolve with history as a driver of future values.

Kordahusen in Alviks strand, Stockholm
Team Fredriksson-Ahlgren-Wingårdhs explored how Kordahusen in Alviks strand can be transformed through minimal intervention.
Through plan studies, models and a full-scale prototype, the team investigated how office environments can be adapted into housing and shared functions while maintaining a high degree of preservation. Particular focus was placed on how existing structures, technical systems and materials can be retained rather than replaced.
The study showed that much of the buildings’ structure and technical systems can remain in place, despite regulations and industry practices that often lead to more extensive rebuilding. The proposals also demonstrate how different functions can coexist over time, enabling gradual transformation.
The team also developed policy proposals related to building expertise, zoning plans, reuse and certification systems. The proposals include more flexible zoning regulations, strengthened expertise in refurbishment and the development of national reuse guarantee systems.

Förvaltningshuset, Umeå University campus
Team Framtidsminne explored Förvaltningshuset at Umeå University campus. The work took its starting point in a critique of how buildings are valued within planning and development processes, where economic calculations are often prioritised over social, cultural and ecological values. The ambition was to develop a model for alternative valuation that can contribute to more nuanced and sustainable transformation strategies.
Through inventories, archival research and interviews, the team mapped the building’s technical, historical and social values. The material was organised into a value matrix that visualises how different values interact and sometimes come into conflict.
Based on this work, the team developed a transformation and management proposal in which new uses are tested within existing structures and with the building’s spatial and architectural qualities as a starting point.
The team’s work also resulted in proposals for policy instruments that can strengthen long-term management, including integrating the value model into planning and maintenance processes. The project demonstrates how a broader understanding of value can contribute to more nuanced and sustainable transformation strategies.
What is needed to reduce barriers and increase incentives for transformation?
The work carried out within Transformation – RE:purpose shows that economic models, taxes and incentives often favour new construction, while the existing values of buildings are undervalued. Building regulations and planning processes affect the possibilities for transformation, but increased flexibility could help support development.
The project also highlights the need for increased expertise, interdisciplinary working methods and better knowledge of existing buildings. Certification systems, guarantees and technical solutions need to be further adapted to reuse and gradual transformation processes.
The project points to the need for reforms that strengthen transformation, resource efficiency and long-term management, where the values of existing buildings are recognised and integrated more systematically into future urban development.
In a joint project report, ArkDes and the project’s expert advisors present 14 further developed policy proposals based on the teams’ work. The report serves as a basis for the continued development of methods and practices within the construction and real estate sectors.
