Yes, you can always add, remove, or change your team members. You will find a link to do this in the participant area on our website.

Teams can have between 1 and 4 participants, therefore individual participation is completely valid.

Participants must send two digital files through the participant area of our website: an “A1 Board” in JPEG or JPG format and a “Project Description” of up to 400 words in PDF format. Both files must be named with the order number that appears in the payment confirmation email you will receive after registering. You can find all the details in the contest briefing under the “Presentation” section.

Yes, you can submit as many proposals as you wish, but you will need to register for the contest as many times as you want to submit proposals.

Some countries have restrictions on international payments, which could prevent your bank from approving the transaction and hinder successful registration. If this occurs, try registering again using a different credit card, preferably from another bank or one that supports international transactions. If the problem persists, please contact us at info@reusingrooftops.com.

In that case, please select any other country (this is only for statistical purposes) and send us an email at info@reusingrooftops.com indicating the country you want listed for your team.

The accepted languages are Spanish, English, and Catalan.

The event is in-person and will be held during the Barcelona Architecture Weeks. We invite you to register on our website to attend in person.

Yes, you can, but we recommend placing it on the proposed prototype block so that the participating projects can be more easily evaluated by the jury.
