Introduction

One of the most common questions businesses ask when planning a workspace transformation is: how long does an office fit out take?

The answer depends on the size, complexity and scope of the project. As an experienced office fit out contractor, we help clients across the South East plan realistic timelines and deliver projects efficiently from concept through to completion.

What Is the Typical Office Fit Out Timeline?

Most office fit out projects take between 4–12 weeks, but this can vary depending on:

  • Size of the workspace

  • Level of design and specification

  • CAT A vs CAT B requirements

  • Building constraints and approvals

A simple CAT A fit out will generally be quicker, while a detailed CAT B project with bespoke features will take longer.

Key Stages of an Office Fit Out

1. Planning and Design (About 2–4 weeks)

This includes space planning, concept design, budgeting and approvals.

2. Pre-Construction (Approx. 1–2 weeks)

Detailed design, procurement and programme finalisation.

3. Construction and Installation (Around 2–8 weeks)

Delivery of building works, M&E installation, partitioning, finishes and furniture.

4. Handover and Completion

Final checks, snagging and project handover.

What Can Affect Your Project Timeline?

Several factors can influence how long your office fit out takes:

  • Landlord approvals and building regulations

  • Availability of materials and specialist equipment

  • Level of design complexity

  • Working in occupied spaces

Working with an experienced design and build contractor helps minimise delays and ensures smooth coordination throughout.

How to Keep Your Office Fit Out on Schedule

A successful project starts with clear planning. To stay on track:

  • Define your requirements early
