Old Billingsgate was chosen because it was the first building in the City of London to adopt environmental principles which are now becoming more common some 40 years later; the conversion from fish market was overseen by Marco Goldschmied of Richard Rogers Partnership (now RSHP) in 1985-88 with environmental engineering by Ove Arup. The practice strongly favoured the retention of historic buildings of quality and agreed to advise the conservation group SAVE on its campaign to preserve the redundant Billingsgate fish market, owned by the City (which proposed to demolish it for redevelopment). It now stands in front of the glass towers of more recent developments in the City.
