No two office fit outs are ever the same. A compact 2,000 sq ft workspace and a 40,000 sq ft headquarters may share similar goals around collaboration, wellbeing and performance. Still, the scale of the project fundamentally changes the design process, delivery strategy, programme and workplace experience.
For growing businesses, understanding how office size affects a fit out project is essential when planning budgets, timelines, and long-term business needs. Smaller offices often require highly efficient space planning and multifunctional design, while larger workspaces demand more detailed coordination across departments, infrastructure and phased delivery.
At COEL, we work across every scale of workspace, from compact creative studios and agile office hubs through to multi-floor headquarters, laboratories and large-scale workplace campuses. While the size of the workspace changes, the focus remains the same: creating environments that support people, strengthen business performance and adapt for future growth.
The scale of an office fit out affects far more than square footage. It influences:
A smaller office often requires every square metre to work harder. Larger workspaces create more opportunities for variety and flexibility, but also introduce greater complexity in coordination, infrastructure and long-term management.
The key is designing a workspace that functions efficiently at its intended scale while remaining adaptable for the future.
Smaller office fit outs typically focus on maximising functionality without compromising the employee experience. Businesses often need collaborative zones, meeting areas, quiet working spaces and breakout facilities within a relatively compact footprint.
This means careful planning becomes critical.
In smaller workplaces, layout efficiency is everything. Design teams must balance circulation space with functionality while ensuring the office still feels open, comfortable and welcoming.
At Crafted, the workspace was designed to support collaboration and creativity within an efficient footprint. Breakout zones, flexible seating and multifunctional areas were carefully integrated to support hybrid working while maintaining a strong visual identity throughout the space.
Similarly, Acteon used thoughtful spatial planning to maximise natural light and create flow throughout a smaller office overlooking the River Wensum. Meeting rooms were repositioned to preserve views and openness across the workspace, helping the office feel significantly larger and more connected to its surroundings.
Compact offices need furniture and layouts that can adapt quickly throughout the working day.
Features often include:
At Agile Analog, acoustic booths and adaptable meeting areas allowed employees to transition between focused work, collaboration and wellbeing spaces without requiring excessive floor area.
Smaller offices often rely on clever zoning rather than physical separation to create different workplace experiences.
Large office fit outs introduce a completely different level of complexity. As projects scale, workplace design becomes increasingly strategic, balancing operational performance, departmental requirements and employee experience across much larger environments.
One of the biggest challenges in larger office environments is maintaining a cohesive workplace identity while supporting multiple working styles.
At Bidwells, more than 40 teams were brought together into a single agile working environment. The workspace included collaborative cafés, touchdown zones, meeting rooms, social areas, and flexible workspaces, all carefully connected through a consistent design language and spatial flow.
Likewise, Birketts combined hospitality-inspired client areas with professional meeting environments and large-scale employee workspaces to support both recruitment ambitions and long-term business growth.
Large projects require careful workplace zoning to ensure teams can collaborate effectively while still having access to quieter, focused environments.
As office size increases, so does the complexity behind the scenes.
Large office fit outs often require:
At Jagex, the three-floor workspace required specialist environments ranging from collaborative gaming lounges and presentation spaces through to focused development areas and sound-sensitive environments.
Meanwhile, projects such as Mishcon de Reya demonstrate how larger offices often require highly detailed planning for privacy, acoustics, and client experience, particularly in professional services environments.
Project scale has a major impact on construction delivery and programme management.
Smaller office fit outs can typically progress more quickly due to:
However, smaller projects still require detailed coordination. In compact workspaces, even minor layout decisions can significantly impact functionality and employee experience.
Larger projects introduce more moving parts and longer lead times.
These projects often involve:
At AMFRESH, the sheer scale of the workspace required careful furniture planning across collaboration areas, meeting rooms, training spaces, wellness rooms and operational workspaces, all while maintaining consistency with the company’s wider global brand.
For large workplace projects, communication and programme management become just as important as design itself.
The employee experience also varies with workspace size.
Smaller workplaces can naturally encourage closer collaboration and stronger team interaction. Design tends to focus on:
This can create highly connected workplaces with strong team identity.
In larger offices, employees often require more varied environments throughout the day.
This may include:
At Sphere Bio, communal environments played a central role in bringing teams together across a large and technically complex workplace. The kitchen and town hall space became a focal point for collaboration, wellbeing and community.
Similarly, Oxford Ionics integrated wellbeing rooms, gaming areas, touchdown spaces and collaborative environments to support a rapidly scaling workforce.
Across both small and large office fit outs, several themes consistently influence successful project delivery.
The earlier workplace strategy, technical planning and employee needs are considered, the smoother the project becomes.
Understanding future growth, hybrid working patterns and operational requirements at the start helps avoid costly changes later.
Regardless of project size, businesses increasingly want workplaces that can evolve.
This includes:
The best workplaces are not simply aesthetically impressive. They actively support recruitment, retention, collaboration, productivity and brand perception.
Whether creating a compact creative studio or a multi-floor headquarters, office design should always align with the organisation’s culture and ambitions.
At COEL, we understand that office size fundamentally shapes the way a workspace is planned, designed and delivered.
From smaller hybrid working hubs to complex headquarters and multifunctional science and technology workspaces, our integrated teams collaborate to ensure every project delivers long-term value, operational performance, and an exceptional employee experience.
Whether maximising efficiency within a compact footprint or coordinating complex, large workplace transformations, successful office fit outs rely on strategic thinking, technical expertise and a clear understanding of how people work best.
Because ultimately, great workplaces are not defined by size alone, but by how effectively they support the people within them.
