CarlO experimental space - sustainable living in Klarenthal

Information on the project

If not here, then where should an all-round beautiful quarter be created that is in harmony with all facets of sustainability?

Oblique aerial view of the former school grounds with a white dashed line around the property boundary. The colors grey and green dominate the photo. You can see the honeycomb-shaped school building and many trees around it. At the edge of the image section are multi-storey residential buildings and a parking deck in the foreground. It is sunny.

In the middle of Klarenthal, where there are already many things that people need to live, the former Carl von Ossietzky School site is being given a new lease of life. Diverse forms of housing that fit in with the surroundings will create a lively place and offer suitable homes for many needs.

There should be fresh air, relaxing and green open spaces for meeting and playing and affordable living space for everyone. People should be able to get by here without a car and enjoy more space for friendly neighborhoods.

Backgrounds

Aims of the project

We have set ourselves ambitious goals for the new quarter. We are striving for

  • The creation of around 300 new apartments, a daycare center and various other public uses and, if possible, the subsequent use of the existing building.
  • Central accommodation of stationary traffic and the possibility for future residents to do without their own car. We take into account the public transport connections, surrounding potential and alternative mobility options.
  • A climate-friendly energy supply through connection to the existing district heating network.
  • And a green and climate-resilient neighborhood through the preservation of important fresh and cold air axes, the careful treatment of local flora and fauna, as well as the creation of high-quality play areas and open spaces.
  • Where possible, these open spaces should be multi-coded, i.e. several functions should overlap in a meaningful way (e.g. recreation, natural space, water infiltration, CO2 storage, biodiversity, sports area, cooling of the environment, feeling at home, place of well-being, and many more).

Rules of the game for sustainable urban development at CarlO

- A yellow background with an irregular, artistic, brush-like shape. - In the center is the white text "LEBENDIGE STADT" in capital letters. - The design looks modern and creative.

Living city

Development of a vibrant neighborhood with a variety of innovative housing options, exploration of potential for densification, testing of flexible floor plans, integration with the surrounding residential development, creation of neighborhood amenities that foster a sense of identity, design of socially and spatially permeable urban and open spaces as neighborhood gathering places, and, if necessary, the establishment of a neighborhood management program to support the process.

- An orange background with an irregular, organic shape, similar to a brushstroke. - In the middle is the white text "NEUE MOBILITÄT" in capital letters. - The design is dynamic and appealing.

New mobility

“...you can get by just fine without a car!”: Developing a neighborhood that is as car-free as possible, creating and promoting alternative mobility options—such as connected mobility services, mobility centers, the creation of shared spaces, and the principle of short distances—with the goal of returning public walkways and traffic areas to the people.

- A green background with an irregular, artistic shape reminiscent of a brushstroke. - In the middle is the white text "CLIMATE-OPTIMIZED CITY GREEN" in capital letters. - The design looks organic and natural, in keeping with the theme of sustainability and urban greening.

Climate-optimized urban greenery

Preservation and, where appropriate, expansion of green spaces, open spaces, playgrounds, and soccer fields; strengthening existing green corridors and creating new community open spaces; removing impervious surfaces from open spaces and implementing climate-optimized design, and enhancing biodiversity through species-rich meadows, flowering and perennial plant areas, as well as succession areas.

Planning process

The image shows a schematic flow chart of a competition procedure. It consists of a horizontal arrow graphic that is divided into several color-coded sections. Each section represents a phase of the procedure, accompanied by symbols and short labels. Green phase (left): Includes "procedure preparation" and "call for competition" with symbols for participation, announcement and a selection committee. Yellow phase (center): Represents the "processing period" and includes an "award". Orange phase (right): Includes "preliminary review" and "further planning services", with symbols for participation and a jury. The graphic visualizes the structured sequence of a planning or competition process.
Competition schedule

Urban and open space planning competition January to April 2024

An urban development and open space planning competition was held from January to April 2024 as the basis for developing a framework plan. When drawing up the competition specifications, we were guided by the analysis of the existing situation, the rules of sustainable urban development, the suggestions of the citizens and formulated high requirements for the urban design.

The design process took place with the participation of experts, politicians and the public. The aim of the competition was to provide a basis for the future development of the former school site into a sustainable residential quarter. A total of 16 teams of urban and landscape planners submitted entries.

A jury with representatives from administration, politics and research made its decision on April 26, 2024. Further information can be found on the website of the Hessen Chamber of Architects (opens in a new tab).
