What is a Category B Fit Out?

While a Category A fitout is focused on all the essential elements of a building, like creating toilet spaces and ensuring the electrical systems are up and running, a Category B (or Cat B) fit out encompasses everything else. At the end of a Cat A fit out you’ll have all the foundations of a building, but the Cat B is putting together everything that makes your work environment unique and stylish. It can include:

Adding internal walls, partitioning, and flooring.

Bringing in furniture, designing meeting room spaces, and break rooms

Creating a reception area and conference space

General decorating, including your company’s branding

This list isn’t exhaustive. Cat B fitouts are more bespoke and tailored to the needs of your organisation. Every project will be different, but you can completely redesign and revitalise a space during a Category B fit out.

Cat B Fit Out Costings

At Virtus, we understand that while Category A fit outs do always involve certain elements (such as fire safety) every building has different structural issues and concerns, and every company has different requirements. When we price up our jobs and give you a quote, it’s completely bespoke and tailored to your project. There isn’t a standard price list. We will work within your budget, and can take on any Category A office fit out, no matter how large or small. We are always open and honest about our pricing, and won’t attach any hidden fees at the end.
