Space Data Is the New Fitout Brief: What JLL’s 2026 Occupancy Benchmarks Mean for Irish Office Design

The JLL Global Occupancy Planning Benchmark Report 2026, published in May 2026, marks a significant moment for the fitout sector. Global office utilisation reached 56% and the gap between actual utilisation and company targets has narrowed for the first time. The report identifies a structural design shift: assigned offices are shrinking while investment accelerates in focus rooms, phone booths, and small meeting areas. Space data accuracy is now the second-highest priority for corporate real estate teams globally, and the fitout brief is increasingly derived from utilisation data rather than headcount ratios.

This shift presents a capability opportunity for Ireland’s fitout sector. Dublin’s multinational occupiers in technology, financial services, and professional services are the same corporate real estate teams the JLL report captures. Practitioners who develop competence in reading and responding to occupancy data will move from delivering against a brief to helping shape one, grounding spatial allocation in how space is actually used.

The report identifies design outcomes utilisation data is generating. Assigned offices are giving way to activity-based environments, with investment in focus rooms, acoustic booths, and small collaboration areas. These are the space types Leesman’s workplace research correlates most strongly with high office experience scores. With 89% of employees ranking focused individual work as their primary activity, utilisation data confirms that quiet, bookable focus zones are consistently underbuilt. Fitout teams entering a brief with occupancy data can specify for actual use rather than inherited assumptions.

The report reveals that more than 70% of organisations are still researching AI for occupancy planning rather than deploying it. Deloitte’s analysis of digital twins in corporate real estate confirms the technology holds equal or greater value for existing buildings as for new construction, enabling real-time monitoring without physical alteration. Fitout contractors who specify sensor networks, smart booking systems, and IoT-ready infrastructure at brief stage serve clients across both delivery and the operational lifecycle.

The commercial stakes in Dublin are high. CBRE Ireland’s Real Estate Market Outlook 2026 confirms prime rents are forecast to rise 8% to €753.50 per square metre in 2026, with Grade A stock constrained. Where every square metre carries a significant occupancy cost, demonstrating that a fitout configuration reflects genuine utilisation patterns gives clients a defensible board-level return-on-investment narrative. Fitout decisions justified by space data are stronger commercial propositions than those derived from benchmarks.

Three capability investments position Irish firms to lead this shift. First, develop a pre-brief space data review service, analysing occupancy sensor readings, badge data, or room booking records before a design concept is produced. Second, specify IoT-ready infrastructure such as power-over-ethernet cabling, sensor mounting provisions, and smart panel capacity as standard in commercial briefs, enabling clients to add data collection capability without retrofit. Third, build working knowledge of occupancy analytics platforms and activity-based design frameworks that translate utilisation data into spatial recommendations.

The JLL data signals that convention-driven fitout briefing is giving way to one grounded in occupancy evidence. Ireland’s fitout sector, serving organisations that treat space data accuracy as a board-level priority, is well positioned to make that transition a commercial advantage. Practitioners who move from delivering a brief to helping define one will find the capability to justify every square metre of specification distinguishes them where it counts most.
