What is a Cat A Fit Out?
A Cat A fitout transforms unutilised building shells into operational commercial spaces by installing essential infrastructure and systems.
Cat B is a custom workspace with custom furniture and design elements; Cat A fitout is the base for all commercial developments.
‘Category (CAT) Fitout’ is essential in office refurbishment. It separates projects into Cat A and Cat B, each with different completion and customisation phases in office space planning and furnishing.

Understanding Cat A and Cat B Fit-Out Differences
Your office renovation project will succeed if you know the main difference between Cat A and Cat B fit-outs.
A Cat A fit-out changes an empty shell into a base ready for further furnishing, with raised floors, suspended ceilings, and primary M&E. Property owner or developer does this stage.
Unlike Cat A works, a Cat B fit out transforms empty shells into fully-functioning workplaces designed to match client requirements. From office layouts to interior finishes and furnishings, these projects are typically completed before occupation to ensure the space perfectly aligns with the company’s vision.
The main contrast between Cat A and Cat B lies in their end result. Cat A delivers a prepared shell, whereas Cat B creates a complete, tailored workspace ready for immediate use.
