When building a wall myself, do I need at least one wall that is 1200mm wide x 2000mm high, which is the standard cube entrance size? Can I specify the starting size?

One opening is required. The opening dimensions (W1200 x H2000) can be changed or specified, but consultation with the secretariat will be required depending on the dimensions and shape.

I have a question about the condition "exhibition inside a cube." For example, would a project like this meet the condition: "Photos will be taken outside the museum every day during the exhibition period, and those photos will be posted inside the cube at the venue every day (in other words, the activities during the exhibition period will be outside, but the exhibition will be inside, and the photos will be updated throughout the period)"?

Whether the project meets the conditions will be determined by the judges. Please include in your proposal a detailed description of how photography will be conducted during the event, the specific times and number of times, and the status of the exhibits within the cube during times when photography is not being conducted.

Can I have unnecessary items removed free of charge when the artwork is removed?

Removal costs will be the responsibility of the seller.
