The Difference Between a Cat A and Cat B Fit Out

Although an office fit out may seem as though it is exactly that – just a fit out – the projects can actually be categorised in one of two ways, each defined by the purpose.

To shed some light on the subject, we’re delving into the meaning of a Cat A fit out and how that compares to a Cat B fit out. Knowing which one is right for you will depend on where you’re standing – do you need a comprehensive fit out or a basic refurbishment of a space that is not fit for purpose?

What is a Cat A Fit Out?

Category A fit outs are simply creating a space which is operational, in its most basic form – laying the foundations. This type of fit out focuses on the core and structure of the building. Raised access floors, ceilings, and flooring, including essential elements such as the installation of the mechanical and electrical elements.

A Cat A fit out creates your blank canvas, ready for your specific preferences to be installed during the Cat B fit out phase.

A Cat A office fit out can often be the most cost-effective option and save your business significant costs in the long run.
