Fit-outs vary depending on client needs and can range from a bare-bones shell to fully furnished, ready-to-use spaces. Understanding the different types of fit-outs can help you choose the best option for your project.

The primary fit-out types include:

  • Shell and Core
  • CAT A
  • CAT A+
  • CAT B

Shell and Core Fit-Out

The Shell and Core fit-out represents the building in its most basic state, where no interior work has been completed. At this stage, the building is structurally complete but not yet usable, with only the external framework and basic infrastructure in place.

Key features of Shell and Core:

  • Building structure (concrete and metal frame)
  • Weatherproofing
  • Lift shafts and lobbies
  • No internal services such as lighting or air conditioning

CAT A Fit-Out

A CAT A fit-out takes the space from bare structure to a basic finished interior, often commissioned by landlords. This fit-out includes essential services, making the space functional but not yet personalized.

Key features of CAT A:

  • Electrical and mechanical systems (lighting, air conditioning)
  • Toilets and basic fire detection systems
  • Raised access floors and grid ceilings
  • Finished internal walls and reception areas
  • Described as a “blank canvas,” ready for tenant customisation into a CAT B space

CAT A+ Fit-Out

CAT A+ is a step between CAT A and CAT B, commonly used by landlords offering flexible lease options. It provides a ‘Plug and Play’ solution where tenants can move in with minimal work required.

Key features of CAT A+:

  • Functional workspace ready for immediate use
  • Meeting rooms, breakout spaces and basic furniture
  • Kitchens and workstations
  • Power and IT infrastructure installed
  • WCs
  • The tenant can still personalise branding and decor after moving in

CAT B Fit-Out

A CAT B fit-out transforms a space into a fully operational and customised workplace. This fit-out is tailored to the client’s specific needs, incorporating design, layout, and aesthetic elements to reflect the company’s brand and culture.

Key features of CAT B:

  • Customised partitions, doors, and flooring
  • Specialist lighting, cafés, kitchen areas and tea points
  • Furniture and bespoke branding
  • Décor and artwork to match the company’s identity

Each fit-out type serves a different purpose, from foundational Shell and Core to personalised CAT B. Consider your needs, budget and timeline to determine which option is right for you.
