From empty desks to energised teams: How Cat B refurbishments transform the office

The shift to hybrid working happened quickly, and most office environments were never redesigned to reflect it. Organisations adapted their policies but not their spaces. The result? A layout built for a world where everyone comes in every day, now hosting a fraction of that footfall. 

This creates what workplace designers refer to as void space and it's more damaging than it first appears. Void space isn't just empty desks. 

It includes: 

• Underused meeting rooms that sit dark for most of the week
• Oversized open-plan areas that feel cavernous with low occupancy
• Dead corridors and circulation paths with no functional purpose
• Breakout spaces that lack energy or a clear reason to use them
• Spaces that no longer reflect how people work today 

When employees arrive to find a half-empty floor and little reason to be there, they question why they bothered commuting. Culture suffers too, the informal conversations, the spontaneous collaboration, the shared energy that makes a team feel like a team, all of these erode when people simply don't cross paths. 

A Cat B refurbishment is a significant investment, but the returns are equally significant. Consider the dual perspective: what it delivers for the organisation, and what it delivers for the individuals who work there. 

For the business: 

• Better utilisation of every square foot
• Reduced void space and wasted real estate costs
• Stronger team cohesion and collaborative culture
• Improved productivity through purpose-built environments
• A space that reflects and reinforces brand identity
• Future-ready design that adapts as the business evolves 

The most effective Cat B refurbishments don't simply fill empty space, they reimagine it. Every underused corner, every overly large meeting room, every quiet corridor represents an opportunity to create something that adds genuine value to the working day. 

Here are the design strategies that make the biggest difference: 

• Agile workplace collaboration zones:  Replace static rows of desking with dynamic, multi-purpose areas that teams can configure for the task at hand: workshops, brainstorming, and project work. 
• Neighbourhood models:  Give teams a dedicated "home base" within the workplace, a sense of territory that reduces fragmentation and encourages consistent attendance on overlap days. 
• Flexible meeting solutions:  Swap large, rarely full boardrooms for smaller huddle rooms, media pods, and mixed-mode collaboration spaces built for hybrid meetings. 
• Social hubs and café anchors:  A well-designed central social space becomes the cultural heartbeat of the office; the place people gravitate to and feel connected through.
• Wellbeing-driven nooks:  Quiet corners, biophilic zones, and decompression spaces turn leftover areas into valued destinations that support mental health and focus. 
• Activity-based layouts:  Every zone is given a clear function - focus, collaboration, socialising, or virtual meetings - so no part of the floor plate goes to waste. 

The organisations leading on workplace experience are already looking ahead. Several emerging workplace trends are shaping how forward-thinking businesses are approaching their Cat B refurbishments: 

• Neighbourhood and team-based planning:  moving away from free-for-all hot-desking towards clustered, team-anchored zones
• Hospitality-led amenities:  café-quality food and beverage, concierge services, and premium finishes that make the office feel like a destination
• Hybrid-first meeting design:  equipping every collaboration space to serve both in-person and remote participants equally well
• Workplace analytics:  using sensor data and occupancy tracking to continuously refine and optimise space allocation over time
• Community-driven layouts: designing for spontaneous interaction, mentorship, and cross-team connection as deliberate outcomes 

These aren't distant trends, they are the benchmark against which employees are already measuring their workplaces. Businesses that invest in a Cat B refurbishment with these principles in mind are positioning themselves to attract and retain talent in an increasingly competitive environment.
