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?
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.
A typical Cat A fit-out includes:
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.
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.
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.
This is where the interior design magic happens, where businesses bring their identity to life through colour schemes, furnishings, and layout.
Cat A includes the bare bones: concrete floors, metal frames, lighting, and HVAC systems. Cat B includes soft furnishings, glass walls, and breakout areas.
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.
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.
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.
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.
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.
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.
Cat A requires more time and effort before move-in, while Cat B offers a bespoke workplace solution ready for action.
Most lease agreements specify that landlords will provide a Cat A fit. This ensures tenants receive a space with essential services installed.
Tenants usually handle the Cat B fit-out, investing in office furniture, design, and layout that reflect their lifestyles and work processes.
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.
Whether Cat A or B, it’s essential to adhere to local regulations, fire protection systems, and building codes during the fit-out process.
Choosing between Cat A and Cat B can bring significant cost savings and avoid duplicate work. A realistic budget is key.
Cat B allows for future-proofing, while a simple Cat A fit might limit your ability to customise or expand.
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.
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.
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.
A Cat A fit-out includes basic finishes such as suspended ceilings, raised floors, lighting, and HVAC systems. Essentially, it’s a blank canvas ready for design.
Depending on size and complexity, a Cat B fit-out may take 6–12 weeks, including custom design, construction, and furniture installation.
Yes, some companies prefer to integrate the two stages for efficiency and to reduce overall fit-out costs.
Typically, the landlord covers the Cat A fit-out while the tenant is responsible for the Cat B stage, depending on the lease terms.
Absolutely. A well-executed Cat B office increases productivity, enhances brand identity, and creates a work environment your team will love.
