We recently completed a lifecycle cost study comparing traditionally built meeting rooms with modular rooms, looking not just at initial cost, but how those costs behave over a typical lease cycle.
This article follows the same structure as a presentation we shared last week, but goes into more detail behind the thinking, assumptions and conclusions.
1. Why we looked beyond the day-one cost of meeting rooms
Most fit-out cost decisions are still made on a day-one capital basis.
That is understandable. It is the point at which budgets are approved, options are compared and schemes are benchmarked. But it also assumes something that rarely holds true in practice: that the space will remain broadly unchanged for the duration of the lease.
Hybrid working, evolving team sizes and changing patterns of collaboration mean that meeting rooms are among the most frequently altered parts of an office.
The question this study set out to test was simple:
What happens to cost when change is treated as inevitable rather than exceptional?
2. Scope and methodology (in brief)
To keep the comparison robust, we modelled a like-for-like suite of meeting rooms using both approaches and tested them across multiple global cities.
The assessment covered four scenarios:
- Day-one installation
- A modest reconfiguration after three years
- A major reconfiguration after seven years
- Full removal and reinstatement at lease end
Traditional construction costs were benchmarked and adjusted for local labour markets. Modular room costs were based on supplier pricing, including delivery and installation. Inflation was applied consistently across all scenarios.
The intention was not to “win” an argument for one solution, but to understand how cost, risk and disruption accumulate over time.
3. Day-one cost of meeting space: a mixed picture
At day one, the results were not uniform.
In higher-cost labour markets, modular rooms were often already cheaper. In lower-cost markets, traditional construction could appear competitive, and in some cases marginally cheaper.
This is usually where the comparison stops — and where many decisions are made.
But day-one cost only tells you what something costs to build once.
4. Reconfiguration of meeting rooms: where the curve bends
The cost profiles diverged sharply once reconfiguration was introduced.
Traditional meeting rooms are effectively single-use assemblies. When layouts change, partitions are demolished, services are altered, finishes removed and waste generated. Much of that cost is repeated each time change occurs.
Modular rooms behave differently. They are dismantled, relocated or reconfigured, often with minimal new material input and significantly less on-site disruption.
Even at a relatively modest level of change after three years, modular rooms became materially more cost-effective in most markets. By year seven, the difference was no longer marginal — it was decisive.
This was not driven by inflation alone. It was driven by repetition of labour, waste and disruption in traditional builds.
5. Programme certainty and occupied buildings
Cost is only one part of the equation.
Traditional construction relies on sequential trades working on site, often over extended periods. In occupied buildings, this introduces programme risk and disruption that are not always fully priced at concept stage.
Modular rooms shift much of that activity off-site. Installation is condensed into days rather than weeks, with fewer trades and fewer interfaces.
From a commercial perspective, that reduction in programme risk and disruption has real value — even if it does not always appear neatly as a line item in a cost plan.
6. End of lease: meeting rooms as assets versus liabilities
One of the clearest differences appeared at lease end.
Traditionally built meeting rooms have no residual value. They are removed and disposed of, and the space reinstated — often at significant cost.
Modular rooms retain value. They can be relocated, reused or sold. In cost terms, that turns what is normally a liability into an asset.
This has implications not just for occupiers, but also for landlords considering how flexible space is offered and how fit-out risk is allocated.
7. Circular economy: commercial, not just environmental
While embodied carbon and circularity were not the primary drivers of the study, the link was unavoidable.
Repeated demolition and rebuild generates waste and carbon by default. Designing for reuse reduces both. More importantly for many decision-makers, it reduces commercial inefficiency.
The circular economy argument only really lands when it aligns with cost, programme and risk. In this case, it does.
8. How to read this study
This study is not intended to suggest that modular solutions are appropriate in all circumstances, or that traditional construction has no place.
Instead, it should be read as a behavioural comparison of cost over time.
The most important takeaway is not any single percentage saving, but the pattern that emerges once change is introduced. Where layouts remain static, differences narrow. Where change occurs – even modestly – costs diverge quickly.
In other words, the findings are most relevant where flexibility is genuinely required, not where it is simply desirable.
9. Conclusions
The main conclusion from the work is straightforward.
The biggest savings did not come from specification tweaks or procurement strategy. They came from accepting that offices change — and designing meeting spaces accordingly.
This is not really about modular versus traditional as a binary choice. It is about whether fit-out strategies reflect the reality of modern occupancy.
When flexibility is planned upfront, it stops being a premium and starts functioning as risk management.
Limitations and assumptions
As with any comparative cost study, the findings should be read in the context of the assumptions made.
The analysis was based on a defined suite of meeting room sizes that reflect common workplace typologies. Individual projects may vary depending on layout density, acoustic requirements, servicing complexity and landlord constraints.
Traditional construction costs were benchmarked using a UK base and adjusted for local conditions using published cost indices. Actual outturn costs will vary depending on procurement strategy, programme, market conditions and contractor pricing at the time of tender.
Modular room costs were based on published supplier pricing, including allowances for delivery and installation. The study assumes standard configurations; bespoke finishes or non-standard integration requirements may affect costs.
Lifecycle scenarios assume representative levels of change over a typical lease cycle. Actual rates of reconfiguration will differ by occupier and business model. Where no reconfiguration occurs, the lifecycle cost differential will reduce.
Inflation was applied consistently across scenarios. No allowance was made for currency fluctuation, tax treatment or financing costs.
Programme durations are indicative and will vary by site conditions, access constraints and landlord requirements.
Embodied carbon commentary is qualitative and intended to provide context rather than a full life-cycle assessment. A project-specific carbon study would be required to quantify absolute impacts.
Final note: traditional build or modular meeting rooms?
This study was intended to support better conversations at the start of projects – not to replace judgement or context. As ever, the right solution depends on how a building is expected to be used, adapted and managed over time.
