What Does a Cat A Fit Out Involve?
A Cat A fitout establishes essential infrastructure within empty commercial shells, preparing them for tenant customisation.
Cat B creates personal workspaces with custom furniture and design features, while Cat A’s fit-out provides the infrastructure across all commercial developments.
‘Category (CAT) Fitout’ is a core concept in office refurbishment. It separates Cat A and Cat B fit-outs; each means different stages of completion and adaptation in the office design and furnishing.

Comparing Cat A and Cat B Office Fit-Outs
A practical office renovation starts with knowing the differences between Cat A and Cat B fit-outs and what they offer.
A Cat A fitout turns an empty box into a basic work space with raised floors, suspended ceilings, and basic M&E. Landlords or developers usually complete this stage.
A Cat B fit out represents the final stage in creating a perfect workplace, transforming basic spaces into customised business environments. Companies undertake these comprehensive projects before moving in, covering everything from office layout to decorative finishes.
What separates Cat A from Cat B is the level of completion and bespoke elements. Cat A provides the foundation, while Cat B delivers a fully-functional, customised office environment.

Planning Your Office Fit Out
Before jumping into your office fit out, take some time to think about these important points:
Budget Considerations
A budget is the foundation of any successful office fit out. Let’s get into the details:
Design fees: Consider the cost of hiring an architect or designer to create a bespoke design for your office space.
Construction costs: Consider the cost of materials, labour, and equipment needed to complete the fit-out.
Furniture and fixture costs: Consider the cost of purchasing new furniture, fixtures, and equipment for your office space.
Additional services: Include the cost of any further services, such as IT infrastructure or audiovisual systems.
Timeline and Project Management
Time management shapes the outcome of any office renovation. Consider these critical planning aspects:
Establish a realistic timeline: When setting a realistic timeline for the fit-out project, consider the complexity of the work and the availability of materials and labour.
Coordinate with stakeholders: Ensure that all stakeholders, including contractors, suppliers, and employees, are aware of the project timeline and milestones.
Regularly update stakeholders: Keep stakeholders informed of progress and any changes to the project timeline.
Address concerns and issues: Promptly and efficiently address any problems or issues that arise during the fit out process.
By carefully planning your office fit out, you can create a workspace that meets your business needs and supports your team’s productivity and well-being.
