The design borrows the utilitarian language of the car park it sits on. The platform is 3.5 metres wide and spans the full width of the deck, its steel beams cantilevering at either end. Staircases on both sides lead to an elevated promenade with unencumbered views of London. The deck and steps are laid in full-width hardwood, and the timber handrails are angled to give natural places to lean and rest. Beneath the steelwork sits a timber-framed kiosk, painted dark blue, serving as information point, ticket booth, shop and staff base, and as a hub for the Bold Everywhere education programme. Conceived as infrastructure for creative production, the Observatory has since housed and staged new commissions, including in 2018 a temporary open-air cinema for Es Devlin's film The Order of Time.
