Its close to St Pauls Cathedral, the new Museum of London, the Elizabeth Line, and within the burgeoning Fleet Street Quarter, which he described as helping turn a too often overlooked part of London into an appealing, walkable destination.He said he hoped the scheme would be one of a wave of new creative reinventions of City buildings, contributing to lower carbon emissions by reusing existing architecture and bringing a greater diversity of activities to the square mile.The building, which is unlisted, retains the principal north and west facades of a four-storey commercial block dating from the early 1870s. While the London stock brick and stone-detailed elevations remain, the structure was substantially reconstructed and extended during the early 1980s.The scheme targets a BREEAM Excellent rating and is intended to support the Citys growing visitor economy.>> Also read:Axiom Architects submits plans to transform City tower into 420-bed Premier Inn>> Also read:Beyond work: how hotels are redefining the office conversion
