Cat A and Cat B Fit Out: Key Differences Explained

In this blog you will discover the key differences between Cat A and Cat B fit outs and learn how each one impacts office design and functionality.  

Creating the ideal workplace requires careful consideration and planning. A key aspect of this process is choosing the right type of fit out. In the world of workplace and office design, you will encounter two main types: Cat A and Cat B fit outs. Each is unique and understanding the differences between the two is essential to creating functional and desirable spaces. So, what sets them apart? Whilst there is no standard industry definition, this blog will explain the differences between a Cat A and Cat B fit out, helping you choose the best solution for your organisation.

What is a Cat A Fit Out?

Cat A fit out definitions refer to it as a base-level office fit out. Think of it as the foundation of a workplace or office. It focuses on essential infrastructure and services, ensuring spaces are ready and functional for basic use. However, the end result is still a blank canvas that’s ready for customisation and personalisation. Think of it like an unfurnished rental.

Key components of a Cat A fit out:

  • Basic lighting, heating, and ventilation.
  • Raised flooring and suspended ceilings.
  • Air conditioning and fire safety systems.
  • Basic internal finishes (walls and floors).
  • Bathrooms.

In short, Cat A provides the structural and mechanical elements needed to operate a workspace, but it’s up to you to add the personal touches. It’s ideal for organisations who want to build on a functional foundation by incorporating their own design elements at a later date.

What is a Cat B Fit Out?

A Cat B fit out takes things a step further. It involves transforming the base infrastructure from Cat A into a fully functional and tailored workspace, that reflects the specific needs and branding of an organisation. Think of it like a fully furnished house.

In essence, a Cat B fit out is tailored entirely to your team's needs and is ready for immediate use upon completion. This is the fit out for businesses and organisations wanting a fully operational, bespoke workplace solution.
