Ultimate Guide to Office Fit-outs - PDF download

Moving offices can be a daunting task, but it doesn’t have to be. Our comprehensive guide to office fit-outs, including commercial office fit-outs and workplace fit-out projects, will walk you through every step of the process, from decision-making to budgeting and location-choosing. Read on for a glimpse of what our guide covers, and download our whitepaper below for an in-depth exploration of the office fit-out process.

What is an office fit-out?

An office fit-out is the process of turning an empty shell of a building into a suitable space for an occupier. This includes furniture such as desks, chairs and computers, core amenities such as electricity and internet access, and finishing touches for branding and decorative purposes.

Office fit-out vs. refurbishment: What’s the difference?

An office fit-out consists of transforming an empty room into a functional space – although the extent of this transformation can range from basic structural work (Shell & Core) to a fully decked-out space with bespoke finishing touches (Cat B).

In comparison, an office refurbishment involves updating an office space to meet current and future needs. This could include making spaces more sustainable and accessible, expanding to accommodate new team members or rebranding.

What are the different types of office fit-out?

We’ll delve more into the different types of office-fit outs in our PDF guide, but here’s just a brief overview as this is one of the main questions we get asked at Interaction:

  • CAT A: a fit-out project that results in a functional yet empty space – a blank canvas for interior designers to work their magic on.
  • CAT B: A CAT B project takes things a step further from a CAT A fit-out – bringing an office to life with decor and custom elements that convey a brand’s unique identity.
  • CAT A+: These are bespoke ‘plug and play spaces’ that have all the core elements of a fitted-out office space – plus the ‘nice to have’ finishing touches. These are increasingly sought after by tenants who want to show up and get straight to work with zero fuss.

How can I decide if I need an office fit-out?

If you think your workplace needs a new lease of life, you may be torn between refurbishing your existing office or finding a new space that you think could be a better fit. There’s a lot to weigh up, so it makes sense to think big-picture at this stage. Here are just a few questions to help get the ball rolling:

  • Does your existing space still allow you to work the way you need?
  • Do your current premises still reflect the aspirations of your organisation?
  • Consider the projected scale of your business over the next 5 years. Can your current space accommodate this?
  • Is your relationship with your landlord a positive one, to the extent that they may help fund renovation works or offer other incentives to stay?

If you’re learning more towards ‘yes’ for any of the above questions, an office fit-out would likely be the best fit for your needs, as opposed to moving offices entirely.

What are the benefits of an office fit-out?

As our guide will show, office fit-outs can offer a multitude of benefits for organisations that want to ensure that their workspace reflects their goals and vision. Here are just a few examples:


This is arguably one of the most important concepts in the modern workspace. Refurbishing your office with flexibility in mind means that you can cater to as many different styles of working as possible. This can take many forms, including breakout rooms for collaborative working or solo workspaces for deep focus.


Over the years, we’ve helped countless landlords, business owners and developers create offices that increase lettable space, attract high-tier commercial tenants and reduce operational costs. We know what it takes to make an office fit-out a lucrative long-term investment.


An office fit-out means organisations can design workspaces around their staff’s specific needs, requirements and preferences. Rather than expecting them to adapt to an existing space, you can create an environment that brings the best out of everyone.


A sustainable office fit-out is great for bolstering your organisation’s CSR credentials, attracting talent seeking a progressive work environment and saving on costs associated with waste and energy efficiency. Also, if you’re looking to gain sustainability credentials such as BREEAM, SKA or LEED, this can be central to your office fit-out strategy.

How do I start with your office fit-out and how long will it take?

To start, you need to launch your office fit-out by determining your current and future workspaces. Evaluate whether your space can scale with you, drive your brand and work mode, and design how your team will operate — the extent to your fit-out could range from a few weeks for light changes to your area per CAT A to several months of full changes to a space per CAT B or CAT A+. Our ‘Ultimate Guide to Office Fit-Outs’ goes through many more elements on how your fit-out can be organised in the most stress-free approach, covering significant stages and raw timelines to ensure things go more smoothly.

How much does an office fit-out usually cost?

The cost of an office fit-out in the UK greatly depends on the size of your space, the complexity of the design, and the quality of materials and furnishings you choose. For instance, ‘plug and play’ fit-outs are more expensive than a Shell and Core project but will allow you to start working or move in commercial tenants immediately. Prices can vary widely, so understanding the specifics of your fit-out is crucial for a more accurate estimate.
