As part of Open House London, together with British artist FXXX BXXXXX, we proposed an intervention in the Argentine Ambassador’s Residence, central to both Argentinian and British identities, and part of their historic rivalry and colonial history. Bringing a typically outdoor activity into a fragile indoor space, our proposal consisted of the installation of an especially designed football pitch in the ballroom. We understood the football pitch as a social space for interaction, a space in which visitors to the house, even if rivals, met in a spirit of participation.
