What is the difference between Shell and Core, CAT A and CAT B fitouts?

In short, a CAT A fitout will be a space that is fully functional but empty.  Whereas a CAT B fitout the space will be suited to your requirements, from custom features to branded finishes.

It is important as the tenant to understand what level of finish the landlord or developer will provide.  Often a space will be provided as either a Shell and Core or a CAT A fitout, leaving you to create the final layout to suit your requirements and this is what we call a CAT B fitout. 

There is no industry standard definition of each of these fitouts so it is essential to confirm with your landlord or fitout partner what will be included during negotiating contracts.

Shell and Core is the basic internal framework of the building, so you expect to see concrete floors and exposed services but will look complete from the outward appearance.  It usually has core amenities completed such as building reception, lifts, and toilet areas.

CAT A fitouts will provide a little bit more than a Shell and Core.  This may include raised floors, suspended ceilings, lighting, fire detection & smoke alarms & basic mechanical, and electrical services.  While CAT A spaces have floors and walls, the specification is often to a basic industrial standard.

Some landlords may request for the space to be returned back to them in CAT A condition at the end of the lease contract, this is known as ‘dilapidations.’

CAT B fitout will provide a space that is ready to move straight into & tailored to the client’s specific requirements and branding.  During a CAT B fitout, you will have partnered with a design and build fitout contractor such as Accent Office Interiors Ltd to design your space to get the best use of space and collaboration areas that align with your brand & culture.

A CAT B fitout will cover everything from interior partitions, IT infrastructure, doors, tea point areas, flooring and even your furniture, incorporating textures, colours and features to reflect and enhance your brand & culture.
