Renaturalising the city, thinking of new ways of adapting the city’s green spaces, without losing building land and responding to the needs of the post-Covid-19 future. This is the aim of the Nou Parc project by the ON-A architecture studio. The proposal consists of creating a 65-acre park around Camp Nou – Barcelona’s football stadium – by raising the topography of the site. This would allow the stadium to function independently from the park and maintain related services including parking, offices, recreational spaces, restaurants, and the museum, underneath the new green surface. In collaboration with Vertical, ON-A has envisioned the use of ‘smart’ technologies for the monitoring and maintenance of green areas and the creation of two lakes to collect rainwater.
