How Do You Create a Secure and Collaborative Defence Workplace?

Written by Candace Fowles | Sep 14, 2026, 2:50:09 PM

A defence organisation creates a secure, comfortable and collaborative workplace by zoning the building by sensitivity, giving open, controlled and confidential collaboration their own spaces, and planning access, acoustics and comfort before design is fixed. At Isembard's 38,000 sq ft London headquarters, Habit Action strengthened access control alongside a CNC power upgrade in 12 weeks.

Key Takeaways

  • Security works best in layers: most secure workplaces need around six zone types, from public reception to secure meeting rooms, not one locked-down building.
  • Collaboration comes in three flavours (open, controlled and confidential) and each needs a different room, not a compromise.
  • Sightlines and circulation routes are security decisions, so they belong in the workplace plan before the fit-out starts.
  • Comfort isn't optional in secure areas: rooms with limited glazing need better ventilation, lighting and acoustics to stay usable.
  • If your site is List X, agree physical security requirements with your security controller before design. At Isembard's 38,000 sq ft London headquarters, access control was designed in alongside the power upgrade.

Walk into a typical corporate office and you might see people gathered around a screen, moving between meeting rooms, grabbing a coffee or finding somewhere quiet to concentrate.

In a defence environment, those everyday interactions can be more complicated.

An engineer might need to discuss a project with a colleague. A leadership team might need a confidential meeting. A manufacturing team might need to collaborate with technical specialists.

The work still needs to happen. But the information being discussed, the equipment being used and even who can enter a particular area may need careful control.

That creates the real workplace design challenge: How do you create an environment that supports collaboration while protecting the things that need to stay secure?

The answer isn't to make everything more restricted. It's to understand what needs protecting, who needs access to it and how the organisation actually works, then design the workplace around those requirements.

What makes a defence workplace secure?

A secure defence workplace starts with understanding that different activities need different levels of protection.

Not every person needs access to every area. Not every conversation needs a secure meeting room. And not every part of the building needs the same physical controls.

A well-planned workplace can therefore create different security zones. That could mean:

    • Public-facing areas for visitors and non-sensitive activity
    • General employee areas with controlled access
    • Restricted project spaces for specific teams
    • Secure meeting rooms for sensitive conversations
    • Specialist areas for manufacturing, engineering or testing
    • Controlled routes between different parts of the facility

Access control can help manage who enters each area, while visitor management can provide another layer of control.

But security isn't just about doors and fobs. The workplace itself can either support or undermine the security strategy.

Consider a meeting room positioned beside a busy circulation route. People walking past might be able to see screens, documents or who is attending the meeting.

A glass-walled room might create useful visual connection in one part of the workplace, but be completely inappropriate somewhere else.

Likewise, a conversation in an open breakout area has very different privacy requirements from one taking place in a controlled meeting room.

Acoustics, sightlines, circulation routes, room positioning and access all become part of the security conversation.

This is why security needs to be considered during workplace planning rather than bolted on once the fit-out is already underway.

How can defence organisations encourage collaboration without compromising security?

The trick is not to choose between security and collaboration. It's to give different types of collaboration the right environment.

Think of it as a spectrum.

Open collaboration

Informal breakout areas and shared social spaces can support everyday conversations, idea sharing and team interaction where sensitive information isn't being discussed.

Controlled collaboration

Project rooms can provide dedicated space for teams working on particular programmes, with access limited to the people who need it.

Confidential collaboration

Secure meeting rooms can provide additional levels of acoustic, visual, access and technology control where conversations involve sensitive information.

This approach creates something much more useful than a workplace where everything is either completely open or completely locked down.

Space

Purpose

Security consideration

Informal breakout

Everyday interaction and conversations

Suitable for non-sensitive discussions

Project space

Collaborative team working

Controlled access where required

Meeting room

Formal meetings and presentations

Acoustic and visual privacy

Secure meeting room

Sensitive discussions

Restricted access and appropriate technology

Focus space

Individual concentration

Privacy and reduced distraction

The important point is that security doesn't have to mean isolation.

People still need to exchange ideas, solve problems and work across teams. The workplace simply needs to make the boundaries around sensitive activity deliberate. And those boundaries should be easy for people to understand.

What should be considered when designing a secure defence workplace?

Security is only one part of the workplace strategy. The physical environment also needs to support the way the organisation operates.

That means looking at five things together.

1. Security requirements

Start by identifying what needs protecting.

Consider information, equipment, people, processes and activities, and understand the organisation's relevant security requirements before developing the layout.

For organisations handling classified information, this may include specific physical security arrangements and requirements associated with Facility Security Clearance (FSC).

The important thing is not to assume every defence organisation needs the same solution.

The security strategy should reflect the actual risk and operational requirements of the organisation.

2. People and movement

Map how people move through the workplace. For example:

  • Who needs access to which areas?
  • Where do visitors go?
  • Which teams need to work closely together?
  • Where could sensitive conversations be overheard or sensitive information be seen?

These questions can influence everything from room locations to circulation routes and access control.

3. Technology and infrastructure

Technology needs to be considered early because it can have a surprisingly large impact on the workplace.

Meeting rooms might require AV and video conferencing. Secure areas may need specialist systems. Access control needs to integrate with the building. Future technology may require additional power, data or service routes.

For defence manufacturers and technically demanding organisations, the conversation can go considerably further.

Power capacity, floor loading, data infrastructure, environmental conditions, specialist utilities, extraction and equipment access can all influence the building.

A workplace shouldn't be designed around what the existing infrastructure happens to allow. The infrastructure should support what the organisation needs the building to do.

4. Employee experience

Security shouldn't automatically result in a workplace that feels clinical or restrictive. People still need somewhere to concentrate, collaborate, meet and take a break.

Natural light, acoustics, ventilation, temperature and ergonomic furniture all contribute to how effectively people can work.

Forget fashionable. The aim is an environment where people can do demanding work without unnecessary friction.

5. Operational continuity

This is particularly important when the workplace sits alongside manufacturing, engineering or other mission-critical activity.

A refurbishment isn't successful if the finished workplace looks great but the project has caused unnecessary disruption to production.

The design and delivery strategy therefore need to consider how the organisation will keep operating while work takes place.

That might mean phased works, temporary arrangements, careful sequencing or separating construction activity from critical operations.

For defence organisations, protecting operational continuity is part of the workplace strategy, not a separate construction issue.

How should technology and infrastructure be planned for future change?

Defence organisations don't stand still.

Contracts change. Teams grow. Technology develops. Manufacturing requirements evolve.

A workplace designed entirely around today's requirements can become restrictive surprisingly quickly. And that's why flexibility needs to be considered alongside security.

Accessible service routes, adaptable layouts, sufficient power and data capacity, and spaces that can accommodate different activities can make future changes considerably easier.

This is especially relevant to defence manufacturers.

A new contract might require additional production capacity. New equipment might increase electrical demand. Automation might change how teams use a space. A growing project team might need more secure collaboration areas.

The workplace needs enough flexibility to respond without requiring a major rebuild every time something changes.

This is where workplace strategy becomes particularly valuable. Instead of asking: "Where can we fit everything today?"

ask: "What might this organisation need the building to support next?"

That can make a significant difference to the long-term value of the fit-out.

What does a secure defence workplace look like in practice?

The balance between security, collaboration and operational capability becomes much clearer when you look at a real project.

Take Isembard.

The organisation needed to scale its advanced manufacturing operation within an accelerated programme. Its work spans rockets, drones, nuclear energy and Formula 1, so the challenge wasn't simply about creating a larger office. The building needed to support the manufacturing operation itself.

Habit Action delivered Isembard's 38,000 sq ft London headquarters in 12 weeks, increasing electrical capacity to support CNC machinery, providing infrastructure for automation, improving production processes and strengthening access control.

The workplace and manufacturing environment were considered together. That matters for any secure manufacturing site, defence or otherwise, because a production facility isn't an office with a workshop bolted on.

The building is part of the operation. People, machinery, technology, power, security and production processes all need to work together.

The same principle applies to the workplace itself. If secure areas are positioned without considering how teams actually collaborate, security can become a barrier to productivity.

If collaboration spaces are created without considering confidentiality, the workplace can introduce unnecessary risk.

If specialist equipment is added without considering infrastructure capacity, the building can limit the organisation's ability to grow.

Good workplace design connects all three: security, people and operational capability.


What are the key principles for a secure and collaborative defence workplace?

The strongest approach can be reduced to five practical principles:

01 — Understand what needs protecting

Don't start with locks, doors and access systems. Start with the information, people, equipment and activities that need protection.

02 — Create different levels of access

Not every person needs access to every space. Use appropriate zoning and access controls so security is targeted rather than unnecessarily restrictive.

03 — Design collaboration around sensitivity

Give people somewhere to collaborate, but make sure the environment reflects the sensitivity of the work. Open, controlled and confidential collaboration can all have a place.

04 — Build security into the workplace infrastructure

Consider access control, acoustics, visual privacy, technology, power, data and specialist services during design.

Trying to solve these requirements after construction usually gives the project fewer options.

05 — Design for the operation, not just the building

The workplace needs to support what the organisation actually does.

For defence manufacturers, that can mean considering manufacturing capacity, specialist equipment, utilities, logistics, security and operational continuity alongside traditional workplace requirements.

So, can a defence workplace really be secure, collaborative and comfortable?

Yes, but it requires a different way of thinking about workplace design.

The most secure-looking building isn't the goal. The goal is an environment where the right people can access the right spaces, sensitive work can happen with appropriate protection, and teams can still collaborate effectively.

That means bringing security, workplace strategy and operational requirements into the same conversation from the beginning.

For a defence organisation, that might mean controlled access and secure meeting rooms.

For a defence manufacturer, it might also mean increased electrical capacity, specialist utilities, production requirements and carefully phased construction.

And for an organisation expecting to grow, it means designing enough flexibility into the workplace to respond to new contracts, new technology and changing teams.

The best secure workplace doesn't make security everyone's problem. It makes security part of how the workplace works.

At Habit Action, we plan security, collaboration and comfort as one brief across defence, advanced manufacturing and other technically demanding environments. A secure room nobody wants to work in is just a very expensive cupboard.

FAQs

What is a secure defence workplace?

A secure defence workplace protects sensitive information, people, equipment and activities while still supporting everyday work. It usually combines controlled access, security zoning, secure meeting rooms, acoustic and visual privacy and appropriate technology. The level of control depends on the organisation's security requirements, so most buildings use layers of security rather than locking down every space to the same standard.

How can defence workplaces support collaboration securely?

Defence workplaces support collaboration securely by matching each type of conversation to the right space. Open breakout areas suit everyday, non-sensitive interaction. Controlled project rooms give programme teams dedicated space with limited access. Secure meeting rooms add acoustic, visual, access and technology controls for confidential discussions. Planning these as a spectrum avoids a workplace that's either completely open or completely locked down.

What is List X and does it affect a fit-out?

List X is a UK commercial site approved to hold classified government information on its premises, under the Government's security framework. Yes, it affects a fit-out. Physical security arrangements, access control, secure areas and contractor access usually need agreeing with the site's security controller and the contracting authority before design is fixed. Contractors working on site may also need vetting.

Can a secure defence workplace still feel comfortable?

Yes. Security and comfort don't have to compete. Natural light, good acoustics, fresh air, temperature control, ergonomic furniture and a choice of places to work can all sit alongside access control and secure rooms. Rooms with limited or no glazing need extra attention to ventilation and lighting, so they stay usable for long meetings rather than becoming somewhere people avoid.

Should security requirements be considered before a defence fit-out begins?

Yes. Security requirements should be agreed as early as possible because they affect the layout, access arrangements, technology, building services and how construction is run. Settling them before design gives the project more options and reduces the risk of expensive changes later, such as moving a secure room or rerouting services once walls and ceilings are already in.

How can a defence workplace be designed for future change?

A defence workplace can be designed for future change by building in flexible layouts, accessible service routes and spare power and data capacity. New contracts, teams and equipment often need more secure collaboration space or more electrical supply. Planning for that from the start means the building can adapt without a major rebuild every time requirements change.
