The revistula net zero workplace redefines Warsaw’s riverfront
ReVistula transforms an existing one office building along WarsawThe front of the Vistula river in a zero workplace landmark. Designed by MJZ with Łoskiewicz Studio for Syrena Real Estate, the project redefines the structure through circular thinking, ecological strategies and new construction technologies. Rather than demolition, the proposal embraces reuse as a forward-looking model for sustainable urban development. Developed with a focus on long-term environmental value, the project caters to international tenants seeking spaces aligned with ESG standards. Designed as both a workplace and prototype, it shows how existing buildings can be developed into leading, climatic landmarks along the riverbank.

circular design and material reuse office architecture shape
MJZ with Łoskiewicz StudioIts design begins with an analysis of the existing structure, sunlight and opportunities to recover materials from the original facade. These elements are repositioned in the new interiors, while the exposed concrete slabs reveal the original construction of the building and reduce the environmental costs of demolition. A new timber-framed glass facade is set deeper into the enclosure, creating natural shading and allowing the slabs to extend as terraces. These terraces are part of an ecological system inspired by the Vistula River, positioning the building as a sensitive living environment.
Water circulation is integrated throughout the building to regulate the indoor climate. Horizontal channels lead water through planted zones, where tall grasses filter and cool it naturally. This hydrobotanical system supports the reuse of gray water while shaping the spatial experience of the building. Vegetation also acts as passive shading, with deeper planting areas providing protection from direct sunlight. Together, the water and plant systems create a multi-layered environmental strategy that improves both performance and comfort.

The roof is designed as a hydrobotanical landscape combining water tanks, greenery and common areas. A large basin connects to the building’s water systems, supporting passive cooling while creating an accessible environment for users. Mechanical systems are moved underground to free up the roof for public use. An additional floor is inserted using a wooden CLT waffle plate structure. Exposed timber columns allow for an open, flexible interior that can accommodate a range of functions, from workspaces to events and leisure.
At ground level, co-working spaces and a restaurant activate the building and strengthen its connection to the city. Interior materials refer to the sandy banks of the Vistula River, while graphic elements draw from local vegetation and the symbol of Warsaw’s mermaid, connecting the project to its cultural context and the client’s identity. Supported by detailed cost analysis and sustainability expertise, the project is aligned with climate neutrality goals and ESG benchmarks. ReVistula proposes a new model for transforming existing buildings into environmentally responsible workplaces that concern both their users and their environment.
