Cat A Fit Out Basics
The Category A (Cat A) process transforms empty shells into prepared commercial spaces by installing fundamental building systems.
Cat B turns spaces into custom furniture and personal design; every commercial project starts with a Cat A fit-out.
‘category (CAT) Fitout’ is vital in office design. It classifies fit-outs as Cat A or Cat B; each category means different levels of finish and customisation in the workplace layout and equipment.

Understanding Cat A and Cat B Fit-Out Differences
When planning your office space, it’s important to know the difference between Cat A and Cat B fit-outs as they serve different business needs and goals.
A Cat A fitout converts empty space into a functional space with raised floors, suspended ceilings, and basic M&E. The Property owner or developer does this stage.
Moving beyond basic infrastructure, a Cat B fit out delivers complete workplace solutions customised to each client’s specifications. Companies typically undertake these detailed fit outs before relocating, ensuring their new space includes all necessary partitions, furniture, and finishing touches.
The primary difference between Cat A and Cat B is the degree of completion and personalisation. Cat A offers a prepared shell, whilst Cat B provides a fully-equipped, bespoke workplace.

Planning Your Office Fit Out
Getting your office fit out right starts with smart planning. These are the basics you’ll need to consider:
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
Before starting your office fit out, establish a solid project timeline. Essential scheduling factors include:
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.
When done right, an office fit out creates more than just a workspace – it builds an environment where your team and business can thrive.
