More Desks, Less Comfort? Rethinking Office Interior Design

High-density workplaces present a difficult challenge for office interior design. Businesses want to accommodate more employees without increasing property costs, but squeezing additional desks into existing floor plans can compromise comfort. Narrow walkways, crowded workstations, excessive noise and limited personal space can make even a modern office unpleasant. South African employers must also consider workplace safety and ergonomic regulations when planning office capacity.

A successful high-density office isn’t necessarily one that fits the most desks into the smallest area. It’s one where employees can move comfortably, adjust their workstations, concentrate and collaborate without disturbing colleagues. Achieving that balance requires thoughtful planning, suitable furniture and an understanding of how employees use their workplace throughout the day.

Why Does Office Density Affect Employee Comfort?

Increasing workstation numbers doesn’t automatically make an office more efficient. Every additional desk introduces another employee, chair and set of movement requirements. Without sufficient clearance, employees may struggle to adjust their seating, access storage or move around without disturbing colleagues.

Research illustrates the importance of these conditions. A 2020 study involving 113 employees across five offices found that workers in shared or open-plan offices performed 14% worse on a concentration task than those in individual offices. Noise differences contributed to this finding.

These results don’t mean open-plan layouts are always unsuitable. They demonstrate why office interior design must consider workstation density alongside acoustic comfort, privacy and employee activities. Businesses should assess whether additional desks genuinely improve operational efficiency or simply introduce new workplace difficulties.

How Much Space Should Each Workstation Have?

South Africa’s General Safety Regulations, amended in March 2025, require at least 2.25 m² of effective open floor area per employee in indoor workplaces, excluding workplaces where building work is performed. This is a minimum workplace safety requirement, not a recommended workstation size.

The distinction matters because furniture occupies space that employees cannot freely use. For example, a desk measuring 1.2 m by 0.6 m occupies 0.72 m² before accounting for seating, storage and circulation. A floor plan showing sufficient desk positions may therefore still be impractical.

Businesses should calculate workstation requirements around actual working activities. Employees need room to move chairs backwards, stand, access belongings and change positions comfortably. Testing furniture arrangements before installation helps identify whether the proposed layout provides enough functional space.

Why Does the Space Behind a Desk Matter?

Chair clearance is easily overlooked when businesses increase workstation numbers. Employees need room to stand, rotate and move backwards without colliding with colleagues. When opposing workstations share a narrow aisle, even ordinary movements can temporarily obstruct circulation.

A desk measuring 1.2 m across its work surface doesn’t reveal how much space its user needs behind it. Chair dimensions, movement requirements and nearby furniture must also be considered when calculating usable space.

Before approving a layout, businesses should test whether neighbouring employees can leave their desks simultaneously. They should also check whether occupied chairs block important routes. These simple observations can identify practical problems that might otherwise remain hidden until employees occupy the office.

Which Areas Should Never Become Additional Desk Space?

Walkways, emergency exits and essential access points should never be sacrificed for additional seating. South Africa’s General Safety Regulations require employers to maintain unobstructed workspaces and keep floors, passages, stairs and walkways in good condition.

The March 2025 amendments reinforce the importance of usable floor space. The 2.25 m² minimum doesn’t automatically establish how many desks can fit safely, especially when furniture and circulation requirements reduce the available area.

Businesses should identify essential movement routes before allocating workstations. Entrances, exits, shared facilities and storage areas need adequate access. Protecting these routes reduces congestion and helps maintain a safer, more organised environment.

How Can Office Interior Design Improve Circulation?

Circulation planning becomes especially important when offices operate near maximum capacity. Poorly positioned desks create bottlenecks around meeting rooms, entrances and shared facilities. Employees may repeatedly interrupt colleagues simply because their usual walking routes pass too close to occupied workstations.

Effective office interior design considers how people move between departments and activities. Businesses should observe movement during busy periods, identify frequently used routes and arrange furniture accordingly. Small layout changes can sometimes improve circulation without reducing workstation numbers.

Practical improvements include:

• Define main walkways: Keep primary circulation routes clear of chairs, storage and unnecessary furniture.
• Reposition shared facilities: Place frequently used amenities away from congested desk areas.
• Group related departments: Reduce unnecessary movement between teams that regularly collaborate.
• Review workstation orientation: Arrange desks to minimise interference between seated employees and passing colleagues.

Circulation also affects accessibility. Employees and visitors have different mobility requirements, making it important to assess routes against applicable accessibility and building requirements rather than assuming every person can navigate narrow passages comfortably.

Businesses should test proposed layouts during realistic working conditions. Observing movement with occupied chairs, open storage and employees using communal facilities provides a more accurate picture than reviewing empty floor plans.

How Can Shared Desks Remain Comfortable for Different Employees?

Shared workstations can reduce the need for permanently assigned desks, particularly where employees follow hybrid schedules. However, one employee’s preferred furniture arrangement may be unsuitable for another person’s height, posture or working activities.

A 2019 study involving 51 office workers found that 73% had used no more than two chair adjustments, despite their chairs offering an average of 5.39 adjustable functions. This highlights the importance of teaching employees how to adjust shared furniture.

Businesses should provide adjustable seating, suitable work surfaces and accessible storage. Clear instructions can help employees configure workstations correctly and return them to a neutral arrangement afterwards. Shared desks should remain comfortable and functional regardless of who uses them.

Which Ergonomic Adjustments Matter Most in Compact Offices?

Ergonomic improvements don’t always require additional floor space. Employees can often achieve more comfortable working positions by adjusting existing furniture. Appropriate lumbar support, monitor placement and keyboard positioning help reduce unnecessary strain without increasing workstation footprints.

South Africa’s Ergonomics Regulations require employers to assess relevant ergonomic risks before work begins and repeat assessments at intervals not exceeding two years. Employers must also review assessments when specified changes or circumstances affect their validity. Furniture purchases alone don’t fulfil these responsibilities.

Useful workstation adjustments include:

• Adjustable seating: Provide suitable back support, seat height and comfortable arm positioning.
• Correct monitor placement: Position screens to minimise awkward neck movements.
• Comfortable keyboard positioning: Keep frequently used equipment within easy reach.
• Appropriate foot support: Ensure employees can maintain comfortable seated positions.
• Regular movement: Encourage employees to change posture rather than remain seated continuously.

The 2019 chair study also found that employees used an average of just 1.86 adjustments per chair. This suggests that businesses should prioritise practical instruction alongside furniture selection, particularly where multiple employees share workstations.

An ergonomic assessment should identify which improvements employees actually need. Some problems require furniture replacement, while others can be addressed through adjustments, revised layouts or changes to working habits. This helps businesses allocate limited refurbishment budgets effectively.

How Can You Reduce Noise When Employees Sit Close Together?

Noise becomes harder to manage as workstation density increases. Telephone calls, conversations and movement overlap, creating distractions throughout the working day. Employees performing concentration-heavy tasks may find these conditions particularly difficult.

Research involving 43 occupied open-plan offices recorded a typical average sound level of approximately 53.6 decibels. While this doesn’t establish a universal noise limit, it provides useful context for understanding the acoustic conditions employees experience.

Businesses should separate frequent callers from employees performing quieter tasks where possible. Sound-absorbing finishes, thoughtful furniture arrangements and designated conversation areas can reduce disruption. Acoustic planning should begin before additional workstations are installed.

Can High-Density Offices Still Provide Privacy and Quiet Spaces?

Private spaces can appear inefficient when businesses are trying to maximise available floor area. However, eliminating them can make confidential conversations, focused work and virtual meetings unnecessarily difficult.

A study involving 113 office employees found that concentration-task performance improved by 16.9% when participants moved from active areas to quiet zones. Moving to individual working rooms produced a 21.9% improvement in the study’s measured performance.

These findings support retaining a practical balance between shared workstations and quieter facilities. A small meeting room or adaptable private workspace can support several activities without requiring every employee to have a permanently enclosed office.

How Do Lighting and Ventilation Affect Comfort in Crowded Offices?

Increasing workstation density changes how employees experience lighting and indoor air conditions. Desks near windows may suffer from glare, while those further inside the building may require additional artificial lighting. More occupants also increase the demands placed on ventilation and temperature control.

South Africa’s Physical Agents Regulations address workplace lighting and indoor air quality, including glare, illumination and ventilation requirements. Businesses should therefore assess whether existing building conditions remain suitable when increasing occupancy, rather than concentrating exclusively on furniture arrangements.

Practical considerations include:

• Natural light: Arrange desks to provide useful daylight without excessive screen glare.
• Task lighting: Provide appropriate lighting for different activities and workstation positions.
• Ventilation: Check whether airflow remains suitable for the intended number of occupants.
• Temperature: Investigate uncomfortable hot or cold areas before increasing density.
• Employee feedback: Identify locations where lighting or air quality regularly causes discomfort.

Workstation orientation can improve visual comfort without major building changes. Positioning screens appropriately and managing direct sunlight may reduce glare, while adjustable lighting helps employees working on different tasks.

Ventilation requires more careful evaluation because additional occupants may exceed the conditions originally considered in the building’s design. Businesses should seek competent advice where necessary and verify that proposed office changes meet applicable requirements.

How Can Businesses Assess Comfort Before Adding More Desks?

The best approach is to evaluate existing conditions before increasing workstation numbers. Observe circulation, employee activities and shared facilities during busy periods. An office that accommodates 30 employees comfortably on quieter days may experience different problems when all 30 attend simultaneously.

Employee feedback identifies difficulties that floor plans cannot reveal. Ask staff about seating, noise, lighting and movement around their workstations. These observations should complement formal ergonomic risk assessments, which South African regulations require at intervals not exceeding two years.

Businesses should then prioritise improvements according to their likely impact. Repositioning furniture or reorganising storage may solve some problems immediately, while inadequate circulation or unsuitable workstation dimensions may require more substantial office interior design changes.

What Office Interior Design Mistakes Make High-Density Workplaces Worse?

One common mistake is assuming that smaller furniture automatically creates a better workplace. Compact desks may increase seating capacity but leave employees without sufficient work surfaces. Removing storage can also create clutter, especially when personal belongings accumulate around workstations.

Another mistake is planning around average attendance rather than peak occupancy. An office might appear spacious when half its employees are present but become congested during departmental meetings or compulsory office days.

Common mistakes to avoid include:

• Overcrowding workstations: Adding desks without allowing for chairs and employee movement.
• Ignoring acoustic conditions: Positioning concentration-heavy roles beside busy conversation areas.
• Removing essential facilities: Sacrificing storage, meeting rooms or quiet spaces for more desks.
• Overlooking ergonomic requirements: Selecting furniture without considering different employees’ needs.
• Neglecting circulation: Allowing furniture to obstruct essential routes.

Effective office interior design evaluates these requirements together. A layout must accommodate working activities, movement and employee comfort, not simply the maximum possible number of workstations.

Businesses should also reconsider designs that appear efficient only when the workplace is empty. Testing layouts with employees present helps reveal problems before they become costly refurbishment mistakes.
