Lloyd’s 1 : 1

The Lloyd's building in London was constructed in the early 1980s based on a vi sion ary design by Richard Rogers and Partners. Its planning and construction transformed the ideas of megastructure and intelligent environment into built reality. Mock-ups (prototypic full-size models) played a crucial role in this, enabling Rogers' team to test and refine the necessary novel constructions and procedures to minimize the risks of such an ambitious project. Lloyd's 1¿:¿1 is the first case study of one of the most important building projects of the late modern era. It showcases pre viously unpublished ma ter ial from the archives of Rogers Stirk Harbour¿+¿Partners, Josef Gartner and Arup to reconstruct the planning process and demonstrate the working methods. Ex amples of how mock-ups were used as research or planning instruments highlight their relevance for further developing building culture.
