What is the difference between CAT A & CAT B fit-out?

What is a CAT A fit-out?

A CAT A fit-out provides a basic standard of finish throughout the empty internal shell of the building (Shell and Core). The finish will mostly be very simple and industrial. This would be the standard of space that landlords would typically lease out, leaving it to the incoming tenants to complete the interior design and build of their workspace in the form of a CAT B fit-out.

It’s worth bearing in mind that the landlord may request at the end of the tenancy that the space is returned back to the CAT A form. This is known as dilapidations.

Cat A fit-out typically includes the following:

  • Raised floors and suspended ceilings (with a basic finish)
  • Basic mechanical and electrical services
  • Fire detection services and smoke alarms
  • Air-conditioning and ventilation (HVAC)
  • Basic internal finishes

What is a Cat B fit-out?

A CAT B fit-out is where you partner with an interior fit-out/design & build company to design and fit-out a CAT A environment to your specification and branding so that it is ready for your company to move into. This is specifically tailored to your business and people requirements. Generally, this includes furniture, partitioning – offices/meeting rooms, technology, break-out spaces etc.

This type of fit-out is really where you make the house your home – designing and building a space that really represents you and your brand and one which truly inspires helping you to attract and retain top talent.

Cat B fit-out typically includes the following:

  • Fully fitted kitchens and non-communal office amenities

  • Workstations and furniture
  • Re-routing air conditioning and power points
  • IT installation and infrastructure
