What are the fit out categories in office fitout design?


For those not familiar with commercial interior design and fitout jargon – terms such as Shell and Core, Cat A, and Cat B can be confusing. Below, we will attempt to bring some clarity to this topic in a plain and simple way so you can know what is involved before you begin the process of an office refurbishment or new office design process.

What is Shell and Core in office fitout design?

Shell and core can be thought of as a building that is little more than a metal frame inside. The building is weather-proof – from the exterior the building has been ‘built’ but the interior is still raw. It’s a blank slate from a builder / designer perspective. The building’s services have yet to be installed. At this stage you have a little bit more than 4 walls.

What is Category A fit out – (Cat A for short)?

Essentially, Category A is a basic landlord fit out. At this stage we are thinking about Mechanical & Electrical (M&E) that is the installation of the building’s:

  • lighting sockets
  • air conditioning ducts
  • toilets
  • finishes to the internal walls
  • reception areas
  • raised access floors
  • suspended ceilings
  • basic fire detection systems
  • finished for lift lobbies

All of these key services come into consideration at this point.

In a Cat A fitting, you will see a shiny raised floor, painted perimeter walls, and a grid ceiling with fitted lights. This is the outlined sketch on our previously blank canvas.

What is Category B fit out?

Category B fit out is when you will really start to see the colour on the canvas and the office design taking shape. By this stage you and your chosen office fitout design partner will see the shape of your new office.

For the Category B office fitout design stage your interior design team will have taken the time to get to know your business and the type of environment you are looking to create with this project.

Category B includes:


  • Reception desk design and reception area layout;
  • Private office design
  • Shared Space and Coworking space design
  • Partitions and doors
  • Meeting room design and conference rooms
  • IT comms in meeting rooms and offices
  • Audio and visual equipment
  • Floor and wall finishes
  • Internal air conditioning
  • Specialist lighting and facilities
  • Kitchen areas, food and beverage areas
  • Office Furniture

Now that you are armed with commercial design industry jargon and can tell your Cats apart, you have taken an important step in selecting the office fitout design partner that is right for you.
