Planning an office space transformation or a move to a new workplace? You’ve probably come across various terms like CAT A, CAT B, or even Shell & Core during your research. Understanding these office fit-out categories is crucial for making informed decisions about your office design and budgeting. This guide will break down the four main types of office fit-outs – Shell & Core, Category A (CAT A), Category A+ (CAT A+) and Category B (CAT B) – so you can confidently choose the option that suits your needs best.
What is an Office Fit Out?
The term “office fit out” refers to the process of making an interior space ready for work. It involves various stages of design and construction, with a focus on creating a functional, comfortable, and aesthetic workspace. Depending on your needs and the stage of completion of your space, fit-outs are categorised into four main types, each serving different purposes and budgets.
Office Fit-Out Categories: Explained
1. Shell & Core
At its most basic level, a Shell & Core fit-out refers to a building that provides the structural framework and essential services but contains no interior finishes or features. Here’s what to expect in a Shell & Core space:
- Completed external building structure (walls, roof, windows, and doors)
- Basic utilities infrastructure (water, electricity, and fire protection systems)
- Unfinished interiors—no ceilings, flooring, wall partitions, or decorative elements
The purpose of Shell & Core is to offer tenants a blank slate, allowing full customisation of the office fit-out to suit their preferences. While ideal for businesses that want complete creative control, this option comes with the responsibility of managing all subsequent construction work.
2. Category A (CAT A)
A CAT A fit-out transforms a Shell & Core space into a functional office with the fundamental elements needed for occupancy. Think of this as creating a “blank canvas” for tenants to add their personal touch later. A typical CAT A office includes:
- Floors and ceiling finishes (e.g., raised floors and suspended ceilings)
- Basic wall coverings
- Lighting and fire detection systems
- HVAC infrastructure (heating, ventilation, and air conditioning systems)
- Basic power outlets and electrical distribution
- Functional lifts and toilets
CAT A fit-outs are generally carried out by landlords who want to make the space ready for commercial tenants. They provide the foundation for further customisation and design.
3. Category A+ (CAT A+/Plug & Play)
CAT A+ offers a middle ground between CAT A and CAT B fit-outs. Also known as “Plug & Play” spaces, these offices go a step beyond CAT A by including some functional and design features, but without full customisation. Here’s what you’ll typically find:
- Pre-installed workstations, meeting rooms, and kitchen areas
- Minimal design features like basic furniture and lighting
- IT infrastructure provision (e.g., network cabling) for immediate start-up
CAT A+ is often favoured by landlords looking to attract tenants to flexible or short-term leases. It provides a cost-effective solution for businesses that need a ready-to-go office without wanting to invest in bespoke branding and design.
4. Category B (CAT B)
A CAT B fit-out takes the office to its final stage. This involves customising and personalising the space to meet the tenant’s specific needs and brand identity. Here’s what CAT B fit-outs typically include:
- Partition walls to create private offices, meeting rooms, and breakout areas
- Fully equipped reception areas and collaborative spaces
- IT and audio-visual systems installed and ready to use
- Personalised lighting, furniture, and décor
- Company branding is integrated into the design
- Fully functional kitchens, cafes, and bathrooms
A CAT B fit-out transforms the basic structure of a CAT A space into a polished, fully operational workplace that aligns with the company’s vision. This type of fit out is often undertaken and funded by tenants moving into a new office.
CAT A vs. CAT B Fit Outs
Now that you know what each type entails, it’s important to understand the key differences between CAT A and CAT B fit-outs. A CAT A fit-out creates a functional, neutral office space, providing the basics needed for occupancy. It’s ideal for landlords preparing a space for leasing or for businesses requiring only the essentials.
On the other hand, a CAT B fit-out is all about creating a tailored workspace. It focuses on everything from aesthetics to functionality, ensuring the space aligns perfectly with a business’s operational needs, culture, and branding. While more expensive and time-intensive, a CAT B fit out delivers a working environment that is ready for use from day one.
Deciding the Right Fit Out for Your Business
When choosing between Shell & Core, CAT A, CAT A+, and CAT B fit-outs, consider the following factors:
Lease Terms
Your responsibilities as a tenant or landlord may influence your choice. Some landlords offer credits or incentives to offset fit-out costs, so review your lease agreement carefully.
Budget
With less extensive features, Shell & Core and CAT A fit-outs are generally the most budget-friendly options. CAT B fit-outs, although more costly, provide a finished office space that’s tailored to your exact needs.
Time Frame
CAT A fit-outs are typically quicker to complete than CAT B. If you’re short on time, consider whether a Plug & Play (CAT A+) space could provide a convenient solution.
Business Needs
Consider your operational requirements, company culture, and brand identity. Do you need an open-plan space or private offices? Is branding essential to your company ethos? These questions will guide you to the best fit-out option.
