The Contravision graphic was applied directly onto the glass of the Park Plaza Westminster Bridge and offers one-way vision so that visitors inside the hotel have a clear view, as well as allowing natural light in from the outside.
It was created using 44 3x1.5m panels printed on an eight-colour EFI Vutek QS 3200 printer and took two days to install using an abseiling team.
Park Plaza Westminster Bridge marketing director Laurence Markham said: "The impact that the banner has produced has been significant and surpassed our initial expectations. It's vital that, for a hotel development of this scale, we and our partners can communicate when it will be opening."
