An ancillary area of a building is an area that supports the function/s of the primary areas, that is, it is not part of the primary purpose of the building, but is required in order that the primary purpose can function.
Examples of ancillary areas include:
- Plant rooms.
- Cleaners’ rooms.
- ICT rooms.
- Building services rooms.
- Storage rooms.
- Circulation spaces.
In residential buildings, ancillary areas include spaces which do not form part of the main dwelling directly, but nonetheless add some useful value, e.g. patio area, office, garage, conservatory, porch, utility room, and so on.
