The design should be developed with care for the existing vegetation and trees. Any interventions involving the soil are preferably kept to a minimum in order to protect tree roots. If a foundation is needed, non-invasive or above-ground solutions are encouraged. As the intervention is temporary, all elements should be removable so the site can be returned to its original state. The proximity to surrounding trees should be considered thoughtfully, with attention to root zones in a way that avoids direct impact on nearby tree canopies.

Key access roads and passageways are indicated on the plan included in the briefing. These routes should remain continuously accessible, with a minimum clearance of 4 metres in width and 4 metres in height, in order to ensure accessibility, fire safety, and access for emergency services and vehicles such as forklifts.

Currently, there is no existing infrastructure for drinking or cooling water at the site. The new installation can be connected to electricity and water, but this requires additional work and budget. If you choose to include taps, showers, or other water points, you will need to provide and install them as part of your project.

There is no formal inventory of materials, salvaged elements, or leftover structures on site for this project. We strongly encourage circular design and material reuse. After the open call, the selected designer will collaborate with us to identify and incorporate available materials, ensuring sustainability and reuse are integrated into the final intervention.

The installation will be built during Horst Atelier in one week in April 2027, mainly by volunteers with varying levels of experience, guided by the designers and supported by an experienced atelier lead and a sub-lead. Preparatory work, such as metal fabrication, can be done in advance by professionals if needed. Horst provides basic tools on site, with additional or specialized equipment rented via the project budget if required. Designers should plan the intervention so that structures, including any covered elements, are safe and feasible for construction by volunteers.

Anyone may apply, regardless of degree, professional status or level of experience. Submissions can be made individually, as part of a collective, or in collaboration with other creative studios.

There is no fixed required level of detail for the submission. Proposals may be more conceptual or more developed, depending on what best communicates the design. You are free to choose the format, size, and orientation of your presentation file. The final submission should consist of one uploaded document, with a maximum of four pages and a total file size of no more than 10 MB. For example: 1 page for the conceptual sketch, 1 page for the written description, 1 page for previous own projects and 1 page for reference projects that inspired you during the design phase.

You can apply via this application form. Applicants will receive a confirmation email from the organisation once their submission has been successfully received.
