Cat A Fit Out vs Cat B Fit Out: Key Differences & Why They Matter

When planning your new office space, one of the first and most important decisions you’ll make is choosing between a Cat A fit-out and a Cat B. This decision can impact your upfront costs, office layout, brand identity, and long-term functionality. In this article, we’ll explore everything you need to know about the Cat A fit-out vs. Cat B: what’s the difference and why it matters?

CAT A Fit out

Understanding Cat A Fit Out

What is a Cat A Fit Out?

A Cat A fit-out provides the basic infrastructure of a commercial space. It’s the blank canvas of the office world, ready for customisation but not yet designed for day-to-day work. A landlord often delivers this to a tenant before the tenant applies their personal touch.

Key Features of Cat A Fit Out

A typical Cat A fit-out includes:

  • Raised floors and suspended ceilings
  • Air conditioning and ventilation systems
  • Fire safety systems
  • Basic internal finishes like plastered walls
  • Lighting and electrical systems
  • Smoke alarms and essential services

Think of it as the core fit-out, functional but not fully furnished. It’s designed to provide the essential infrastructure for a business to build upon.

Why Businesses Start with Cat A

For tenants, a Cat A office offers flexibility. It’s essentially an empty shell, offering just enough for a business to shape it into something unique. Landlords often provide a Cat A space to meet lease obligations while leaving the final design to tenants.

Diving Into Cat B Fit Out

What is a Cat B Fit Out?

A Cat B fit-out builds upon the Cat A structure and creates a fully functional, move-in-ready office. It reflects a company’s brand identity, culture, and day-to-day needs.

Core Features of Cat B

  • Partitioned meeting rooms
  • Office furniture and storage units
  • Breakout spaces and break rooms
  • Kitchenettes and shower facilities
  • Branding elements and bespoke design
  • Lighting suited for workstations tailored to teams

This is where the interior design magic happens, where businesses bring their identity to life through colour schemes, furnishings, and layout.

Cat A vs. Cat B Fit Outs: A Side-by-Side Comparison

Structural Differences

Cat A includes the bare bones: concrete floors, metal frames, lighting, and HVAC systems. Cat B includes soft furnishings, glass walls, and breakout areas.

Functionality and Readiness

Cat A provides basic mechanical and electrical services. In contrast, Cat B is about creating a customised space for actual use, complete with meeting rooms, access floors, and decorative elements.

Fit Out Costs and Budgeting

Cat A might seem cheaper at first glance, but the fit-out costs increase when transformed into a Cat B space. However, a well-planned Cat B fit can result in better space planning, staff satisfaction, and long-term cost savings.

The Fit Out Process Explained

From Shell and Core to Cat A

Before Cat A, there was shell and core, an even more stripped-down version. The core-shell phase included just the concrete structure, without any finishes or services.

Transforming Cat A into a Customised Cat B Office

The Cat B fit-out involves collaborating with an office fit-out specialist to ensure that every detail, from electrical services to branding elements, is tailored to your needs.

Why Your Choice Between Cat A and Cat B Matters

How Office Fit-Outs Affect Your Team and Culture

A Cat B office allows you to integrate features that reflect your company culture, such as breakout areas, creative zones, and workstations tailored to daily routines.

Brand Identity and First Impressions

Visitors and clients form opinions quickly. A Cat B fit-out enables a strong first impression with visible elements of your company’s brand identity.

Immediate Occupancy vs. Customised Office Design

Cat A requires more time and effort before move-in, while Cat B offers a bespoke workplace solution ready for action.

Leasing Agreements and Responsibilities

What Landlords Provide

Most lease agreements specify that landlords will provide a Cat A fit. This ensures tenants receive a space with essential services installed.

What Tenants Need to Complete

Tenants usually handle the Cat B fit-out, investing in office furniture, design, and layout that reflect their lifestyles and work processes.

Space Planning and Functional Design

Office Layout and Practical Design Features

Effective space planning in a Cat B fitout enhances productivity and well-being. Features like natural light, break rooms, and shower facilities contribute to a positive working experience.

Meeting Compliance and Building Codes

Whether Cat A or B, it’s essential to adhere to local regulations, fire protection systems, and building codes during the fit-out process.

Long-Term Considerations

Cost Savings with the Right Fit

Choosing between Cat A and Cat B can bring significant cost savings and avoid duplicate work. A realistic budget is key.

Flexibility for Growth and Change

Cat B allows for future-proofing, while a simple Cat A fit might limit your ability to customise or expand.

Making the Right Decision

Evaluate Your Office Needs

Consider your team size, brand image, and daily use of space. Do you need meeting rooms or breakout areas? A fully furnished Cat B office might be your best bet.

Work With the Right Fit Out Partner

Choose a partner with a proven track record who will work closely with you, understand your personal preferences, and offer a bespoke design that reflects your unique lifestyle.

Conclusion

Choosing between a Cat A fit-out and a Cat B fit-out isn’t just a design decision. It’s a strategic one. Each option offers distinct benefits, from cost and timeline to branding and productivity. Assess your needs, consult professionals, and make a decision that aligns with your company’s growth and culture. Your dream office space awaits.
