BS EN ISO 4157-2:1999 is a standard that sets out requirements for the designation systems used for rooms, areas, spaces, and voids in buildings that are in regular use. This standard provides guidelines for the naming and numbering of these spaces in order to facilitate effective communication and clarity in construction drawings. By implementing a standardized system for designating rooms and areas, this standard aims to improve communication between stakeholders involved in the planning, construction, and maintenance of buildings. Compliance with this standard ensures consistency and coherence in the designation of spaces within a building, enabling better understanding and coordination throughout the project lifecycle.
