The former headquarters of the London Guarantee & Accident Group now shines in new splendour at the prominent intersection of Michigan Avenue and Wacker Drive. The plan was to convert the ageing complex into a luxury hotel and restore it to its former glory. However, the status of the structure – which was declared a listed building in 1996 – had a major impact on the plans to convert the magnificent neo-Gothic building, which got under way in 2013.
Technical solutions were needed in order to ensure that the project complied with the official requirements. A particularly tricky problem that needed to be overcome was connecting the 452 hotel rooms to the pipe system when ceiling feed-throughs were strictly limited. Early in the design stage, Geberit’s technical advisors raised the possibility of horizontal storey-based drainage in combination with the Duofix installation system. This solution ensured that the concrete floors remained intact and there was no longer anything standing in the way of the historic giant being given a new lease of life.
