Shell & Core vs Fit-Out: What’s the Difference?

Understanding the difference between shell & core and fit-out works is essential when planning electrical installations.

Shell & Core

This phase includes the base-build infrastructure of a building, such as:

• Main electrical intake

• Distribution systems

• Riser containment

• Core services

The focus is on creating a functional framework ready for further development.

Fit-Out

Fit-out involves installing the systems required for the final use of the space, including:

• Lighting

• Small power

• Final connections

• Specialist systems

This stage is more detailed and closely linked to the end user’s requirements.

Why It Matters

Each phase requires a different approach to planning, coordination, and delivery. Clear understanding ensures works are properly scoped and priced.

Conclusion
Shell & core builds the foundation — fit-out completes the space. Both are critical to a successful project.
