COVID CODED is an exploration of the architectural agency in socio-spatial evolution amidst a crisis. It is an inquiry into how a collective forced experiment can be a departure point for architectural adaptability and rearrangement. Historically, Tuberculosis, Cholera, and Polio are among many infectious diseases to have shaped reform. SARS-CoV-2 both can and should write a new chapter on the architectural discipline’s response to the fear of infection. With the new-found gravity of home and Sweden’s population spending approximately 90% of their time indoors, COVID CODED focuses on dwellings and the opportunity to approach the existing to accommodate for new emerging lifestyles. In addition, Pandemic times make society at large prone to isolation and altered interaction. A particularly vulnerable group during crises is the single household, currently estimated to make up 40% of Swedish households. To combat this, COVID CODED explores a collective living typology for the single household designed to be more local, healthy, and agile. With Umeå city as a frame of reference, the Haga/Sandbacka area is host to the largest number of single households compared to other districts. Haga’s proximity to green spaces, educational institutions, service points, and cultural centres, makes the location an ideal host for densification and a 15-minute neighbourhood. Located along Östra Kyrkogatan, the plots of Kryssaren 6 and Kryssaren 7 are currently under consideration by Umeå Municipality to be supplemented and rebuilt to host 20 rentable apartments. COVID CODED adapt these intentions two-fold, first for Kryssaren 6 to receive an extension instead of a separate addition and secondly for Kryssaren 7 to be remodelled instead of demolished. The two techniques reflect ways to approach the existing to increase community support for the single household and create a sense of belonging, ownership, and security. In a larger scope, movements such as the European Green Deal, the Renovation Wave, and the New European Bauhaus are already creating ideal conditions to facilitate change in the same direction!
