The design borrows the utilitarian language of the car park it sits on. The platform is 3.5 metres wide and 32 metres long, spanning the full width of the deck on locally sourced steel beams that cantilever 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. It is sized for the crowds of a single event, and was built on a very low budget with Bold Tendencies managing delivery through local suppliers. Conceived as infrastructure for creative production, the Observatory has since housed and staged new commissions, including in 2018 as a temporary open-air cinema for Es Devlin's film The Order of Time.
