If you ask us, there is way too much jargon on the office fit-out and office design world. That’s why we’ve put together a quick and simple guide so that you know what we’re talking about when it comes to a Cat A and Cat B fit out in your commercial space.

The short version; A Cat A fit out is a space that is fully functional but is empty of things such as furniture, branded materials, decoration and sometimes even partitions. Whereas a Cat B fit out is means that the space has been tailored to the occupant’s specific needs and wants and includes all the finishing touches. This means that once the service is complete, the business and employees will be handed an office or space which is fully functioning and can be worked in right away.

What is an office fit out?

An office fit out can consist of a turn-key service in which a contractor is commissioned to develop your commercial space into an amazing office that you and your team will love day in and day out.

There are a few different types of office fit out that you can choose from, each one offers its own qualities but choosing the right one will depend on the kind of service you’re looking for. The different types of fit outs represent each stage of the process. so, there is a shell and core stage which is the most simple version of the space, a Cat A and a Cat B. The last two are most commonly talked about and seen through the industry due to the fact that they create a more habitable and reasonable finish.

Shell and Core

As you can see from the image above, the shell and core stage of the office fit-out process is pretty much what it says on the tin. With this category of fit-out, we’re here to make everything is structurally sound and start to prepare the space for the rest of the process. This might be to clean and clear the space or even to perform an office rip-out and dilapidation works.

This is one of the least common types of fit-outs because this is literally the barebones of the building. The space isn’t actually usable and so you simply have a shell of the office space. Most of the time a shell and core fit out is just metal and concrete that has been sealed and waterproofed so while it might look like a functioning office from the outside, inside it doesn’t even have lighting or air conditioning yet!

Shell and core fit-out include:

  • Lobbies
  • Lift shafts
  • Concrete and metal frames
  • Structural frames

What is a Cat A Fit Out?

A Cat A fit-out, as mentioned before; offers a functioning office space that has air conditioning, lighting, data points and more already installed. So, if you wanted to you could purchase a few desks and the rest of the equipment that you might need and move right in. But your office space wouldn’t look good, it would still need a lot of work to tailor the rooms to suit your needs. With this type of fit out, you may also need to install a kitchen area and other facilities like this.

This kind of finish is really basic and so it should be treated like a blank canvas that can be adapted to suit your company’s personality. You usually won’t see any concrete or brickwork unless it’s in the design. Usually, you’ll be presented with plasterboard walls, temporary lighting fixtures and an open-plan layout.

After a Cat A fit out, most projects then move into the Cat B phase…
