Your Cat B Fit Out Questions Answered

What is a Cat B fit out?

A Cat B fit out transforms an internal space into a fully operational workplace. Unlike a Cat A fit that prepares the basics, a Cat B fit out involves installing partitions, office furniture, meeting rooms, tea points, breakout spaces, and finishes like ceiling design and brand detailing. It takes the internal surface finishes and electrical systems and turns them into a space ready for immediate occupancy.

A shell and core office is just a concrete shell with no internal finishes, essentially an empty shell. A Cat A fit includes raised floors, suspended ceilings, fire detection, and air conditioning, making the internal space suitable for lease. A Cat B fit out, also known as Category B, adds everything else: office layout, furniture, power points, reception areas, and interior partitions that reflect your company’s needs.

Cat B is ideal for businesses moving into a new office space or customising an existing one. If you’re handed a blank canvas or a Cat A base, a Cat B fit allows you to tailor the internal space to your team’s workflow and operational needs. It’s the final stage of most office fit outs and is essential for companies looking to create a functional office aligned with their brand.

A Cat B fit out typically includes meeting rooms, breakout spaces, tea points, office furniture, ceiling design, electrical services, lighting, and all interior space finishes. It also includes layout planning, staircase installation (if needed), and protection services to ensure building regulations are met. The result is a fully fitted, branded, and practical workspace for incoming tenants.

Yes. As a trusted fit out contractor, we either work with your preferred designer or connect you with a fit out specialist. Together, we’ll plan the office layout, select materials, and design a Cat B space that suits your culture, workflow, and team. We also make informed decisions about infrastructure design to maximise long-term flexibility.

The duration depends on the size of the office space, the complexity of the design, and whether it’s a new office or part of a staged build. After a site visit, we provide a detailed timeline. Our process ensures smooth installation of systems like smoke alarms, air conditioning, lighting, and basic mechanical services without unnecessary delays.

Yes. We frequently manage both stages of the fit out cat process, from the Cat A infrastructure to the final Cat B office fit out. Combining both allows better cost control, continuity, and quality, especially if you’re moving into a new office space that started as just a shell or basic level fit.
