2023 included the completion of Cadoganâs largest development in 15 years, the 220,000 sq ft Gaumont, on the site of the former Gaumont Palace Theatre. The project includes offices, 47 apartments ,a rooftop bar and a 600 seater Curzon picturehouse. Initial planning approval for the proposal, featuring a smaller cinema, had been rejected in 2014 before Cadogan submitted revised proposals. The building compelted last year and Cadogan is âwell advanced in marketing different elementsâ, Seaborn said.
