The 2025 Challenge

This year, we challenge you to transform the rooftop of an existing building into a publicly accessible space that embodies sustainability, community, and creativity. As part of our mission to create sustainable, community-focused environments in Asiat Park, the winning design will make the rooftop a vibrant hub for locals and visitors during the Horst Arts & Music Festival.

Your design should prioritise circular design, emphasizing sustainability, material reuse, and innovative approaches to reducing waste. It should also focus on community integration, fostering connection, inclusivity, and shared experiences.

The competition will involve a two-phase selection process: designers submit initial conceptual sketches, and the top five candidates will be invited to refine and pitch their ideas. We encourage projects that interpret sustainability broadly—whether through material choices, social impact, or circular construction methods

Your creation will not only enhance the festival experience but also contribute to Asiat Park’s evolution into a vibrant, imaginative public space.

Submission Details & Budget

Phase 1: application

We ask that designers submit the following:

• Portfolio or reference projects: previous work or relevant projects that showcase your ability to design public spaces or similar projects.
• Very initial conceptual sketch: a rough, early-stage sketch or outline of your design for the rooftop. This doesn't need to be highly detailed—just an initial idea of how the space might look and function.
• Written description: A brief description of your concept, how it integrates with the existing surroundings, and how it aligns with sustainability goals and accessibility.

Submission Format:

• Maximum number of pages/images: we recommend limiting submissions to 4 pages or images (for example: 1 page for the conceptual sketch, 1 page for the written description, and up to 2 pages for reference projects or additional details). This ensures a manageable amount of work for all participants and avoids excessive time investment, particularly for collectives.

We want to make sure that the process remains efficient and fair for all involved, without requiring an overwhelming amount of design work at this early stage.

Phase 2: jury selection

Five shortlisted teams will present their projects to a jury composed of Horst Arts & Music and fritz-kola representatives.

Selection Process:

• First round: all submitted applications will be reviewed, and five finalists will be selected based on creativity, feasibility, and alignment with the project’s goals.
• Second round: the selected finalists will be invited to pitch their designs and provide further details. Designers selected to present their ideas in this stage will receive a small fee of €300 for preparing and delivering their pitch.

Phase 3: realisation

The winning team will receive €8,500 to bring their vision to life, covering the full production budget (materials, compensation, gear, etc.). In addition, we’ve allocated a €2,700 fee, which, combined with the €300 participation reward for the second round, totals €3,000.

The project will be executed as part of the Horst Atelier, offering designers and builders the chance to immerse themselves in a creative and collaborative environment. Participants will enjoy three freshly prepared meals a day, take part in evening activities, and, if desired, stay overnight in tents.

To support a potential site visit, we’ve set aside a €500 travel budget. All costs related to project documentation and storytelling will be covered by Horst Arts & Music and fritz-kola, ensuring your work receives the attention it deserves.
