Extensa is currently redeveloping the Maritime Station, and announced plans to reopen the freight station in 2020 as a year-round "covered neighbourhood" with workspaces, a food hall, gardens and events space. The renovated station will use geothermal energy along with repurposed paving stones and wood from the original building. It will use electrochromic technology for its intelligent glass window glazing, which uses electric pulses to adjust the opacity of each window, with the option of creating either a dimmed or one-way mirror effect. Standalone workspaces made from wooden modules are anticipated to accommodate 2,000 people within the station.
