To enable the escalators to reach the existing platforms without excessive below ground reconstruction or interference with station operations a new ticket hall was constructed under the Brompton Road/Knightsbridge/Sloane Street junction and new circulation passages were constructed at the lower level.
For at kunne føre rulletrapperne ned til de eksisterende perroner uden massive underjordiske ombygninger eller store driftsforstyrrelser, blev en ny billethal anlagt under Brompton Road/Knightsbridge/Sloane Street-krydset og nye cirkulationsgange blev anlagt i det nedre niveau.
