The Coleg Harlech building was originally a residential adult education college for mature students from 1927 until 2017. The proposition will repurpose the existing to create a sustainable community environment where residents have both private individual living accommodation and a vibrant communal space. Considering the history of the site, the new concept aims to preserve elements of the original architecture and materials whilst creating a new atrium allowing natural light to come through the building to house a range of communal spaces in a unique atmosphere. The atrium serves as a shared space where residents can grow plants, fruit and vegetables supported by an integrated aquaponic system. For the individual living accommodation, expandable spaces can be used as terraces or room extensions. This proposal aspires to create a sustainable community, an environment that brings people together and creates a strong connection with nature.
