What Is The Difference Between A CAT A And CAT B Fit-out?


The terms ‘CAT A’ and ‘CAT B’ can be very confusing for those not familiar with industry jargon, but in this post we explain what they actually mean. The definition of what category A and B entail can vary between developers, but typically they consist of:

Category A:

What a developer would provide in a rentable space or how a building would be handed over following construction. These are essential works that would allow the building to be practically occupied and tend to be the same for all CAT A fit outs:

  • Raised floors
  • Suspended ceilings
  • Installation of mechanical and electrical services (e.g. lighting, controls, A/C)
  • General decoration of walls
  • Blinds

Category B:
This can vary depending on the occupier’s specific requirements and how they would like the office environment to look, but typically includes the installation of items that allow a space to become an office:

  • Doors and partitions
  • Reception areas
  • Kitchen areas and teapoints
  • Furniture
  • Office spaces
  • Meeting and conference rooms
  • IT and AV installations
  • Floor finishes
  • Branding and finishing touches
