The difference between a Cat A and Cat B office fit out


There is a big difference between a Category A and Category B office fit out (Cat A & B for short). These umbrella terms don’t necessarily provide any insight into what’s involved and if you’re embarking on your first office relocation or office refurbishment project, there is a lot of new information to take on board. It’s important to know what you are talking about and what type of office space you might be signing up to. So, what defines Cat A and Cat B fit out?

Shell and core

Taking the building back to ‘shell and core’ means that your building will have no services within the space and will only be the exposed structure of the property.

A Cat A office fit out will usually include installing the essential services of the property, creating a blank, operational space. It is ready for you to move into but it will be exactly that - no individual rooms, furniture or design features. It is your bare bones space, ready to be transformed into a working environment with a Cat B fit out.
