What Is a Commercial Fit Out? Everything You Need to Know

A commercial fit out is the process of transforming an empty or shell space into a fully functional working environment, tailored to a business’s needs. Whether it’s an office, retail store, school, lab, or industrial unit, a fit out is what turns the blank canvas of a building into a place where work actually happens.

But not all fit outs are the same. There are different types and understanding the process can help business owners and property managers make smarter decisions.

Fit Out vs Refurbishment

It’s easy to confuse the two. A fit out refers to the initial setup of a space that’s never been occupied (or has been stripped back to its shell), while refurbishment is about updating an existing space.

The Types of Commercial Fit Outs

  • Shell & Core: The basic structure is in place — walls, floors, lifts, and mains services — but no internal finishes.
  • CAT A Fit Out: Adds basic finishes such as suspended ceilings, raised floors, lighting, and HVAC. Making the space ready for occupation.
  • CAT B Fit Out: Where the transformation really happens. This includes interior walls, meeting rooms, kitchens, furniture, branding, tech, and more . CAT B Fit outs are designed around how your team works.

Some fit outs also include turnkey delivery, where a single team handles everything from design to handover. It’s end-to-end, and hassle-free.
