Situated in the Donado-Holmberg neighbourhood in north Buenos Aires—a recent renovation of a once-neglected part of the city—Casa HO is a new mixed-use housing project that bets on bikes as the mobility system for the future of the city. Designed by Grupo Uno En Uno, the complex features a huge ramp in its central courtyard which works both as a sculptural and circulation device to connect the different uses of the building. Presented by Open House Buenos Aires, for the 2020 Open House Worldwide Festival, the tour visits the building with one of its architects.
