What is the difference between Cat A and Cat B?

There can be vastly different standards of a Cat A and Cat B fit out, depending on what you negotiate. While most of our projects are a full Cat B, designed with furniture and workplace interactions in mind, some landlord-provided ‘Cat B’ spaces may only include room partitions, tea points, and carpeting.

If you have found a new space with a Cat A and Cat B fit out, our team can work with you to create your ideal environment while maximizing the existing building services.

What is Cat A Fit Out?

While there’s no standard specification, Cat A and Cat B fit out projects generally start with a Cat A space (also known as a Category A fit out), which includes a suspended ceiling, lighting, heating, and raised flooring. This creates a functional space that landlords lease to tenants, who then install the final design elements and finishes to meet their workplace needs through a Cat B fit out.

A Cat A space provides the essential infrastructure but is often a blank canvas for interior and office designers. If you’re thinking you can move in and furnish the space right away, you might want to think again! Without a Cat A and Cat B fit out, you won’t have your breakout areas, meeting rooms, or a cozy kitchen to enjoy a cup of coffee.

What’s usually included in your Cat A fit out:

Raised floors and suspended ceilings (with a basic finish)
Basic mechanical and electrical services
Fire detection services and smoke alarms
Air-conditioning and ventilation (HVAC)
Basic internal finishes

What is Cat B Fit Out?

A Cat A and Cat B fit out project moves from the initial Cat A stage into Cat B, which transforms the space into a fully functional workplace. Cat B (also known as Category B fit out) is tailored to a company’s needs, allowing businesses to move in and start working immediately.

Turning a blank Cat A space into a functional Cat A and Cat B fit out requires careful planning. A well-executed Cat B fit out should reflect your brand and work ethos, incorporating furniture and design elements that enhance your office environment. More than just desks and partitions, it ensures that your office becomes a space where employees love to work while also helping you attract and retain top talent.
