Zimnyaya Kasha was founded in 2010 by a team of urban planners, architects, and environmental scientists who shared a vision: to transform Swedish cities into models of sustainability that enhance quality of life while minimizing environmental impact.
What began as a small consultancy in Stockholm has grown into one of Sweden's leading firms specializing in sustainable urban development, with projects across the country and international recognition for our innovative approach.
Throughout our journey, we've maintained our core commitment to creating urban environments that are not just environmentally sustainable, but also socially equitable and economically vibrant. We believe that truly sustainable cities must address all three dimensions of sustainability in an integrated approach.
Guiding principles that shape our approach to urban development
To transform urban environments through sustainable practices and innovative solutions that create resilient, inclusive, and vibrant cities for current and future generations.
We prioritize ecological health and resource efficiency in all our projects, recognizing that cities must work with natural systems rather than against them.
We believe that sustainable cities must be inclusive, providing accessible opportunities and high quality of life for residents of all backgrounds and income levels.
We continuously explore new approaches, technologies, and design solutions that challenge conventional urban development practices.
We work in partnership with communities, municipalities, developers, and other stakeholders, recognizing that sustainable urban development requires diverse perspectives and expertise.
