Space Planning & Office Layout Optimization Using Facility Data
By Jhon Polus on March 24, 2026
Most office portfolios are optimised for a workforce that no longer exists. Floor plans designed for pre-pandemic headcounts are running at 38% to 52% average utilisation, with FM teams paying full operating cost for layouts that no longer match how space is actually used. Data-driven space planning converts occupancy evidence into layout decisions and CapEx cases that reduce facility cost while improving the experience of occupants who do come in.

Space Planning Data and PM Scheduling in One Platform
Oxmaint connects occupancy sensor feeds, booking system data, and asset records into one space management platform. FM teams get utilisation heat maps, zone-level reporting, and CapEx forecasting for right-sizing decisions. Book a demo to see space analytics configured for your portfolio.
Data-driven space planning is the practice of making office layout, zone allocation, and right-sizing decisions based on measured occupancy evidence rather than headcount assumptions, lease terms, or manager estimates. It uses sensor data, booking system logs, badge access records, and FM asset data to produce a utilisation picture that is accurate to the zone level and updated continuously, not just at annual lease renewal review.
For FM teams, the distinction matters operationally. A floor plan redesign based on headcount assumptions 30% higher than actual occupancy produces a new layout that is still inefficient. The same redesign based on 12 months of hourly occupancy data by zone matches actual demand patterns across the full working week.

Connect All Space Data Sources Into One Platform
Oxmaint integrates with occupancy sensors, booking systems, and badge access via API to feed live utilisation data into zone-level asset records. FM teams get one space management view across all data sources. Book a demo to see the space data integration for your building stack.
Fixed-assigned desks with utilisation below 50% on average should be converted to hot-desk pools. Each converted desk reduces annual cost by $8K to $14K and improves space yield. Target: retain fixed desks only for roles requiring consistent equipment configuration.
Conversion threshold: Below 55% average utilisation
Collaboration Zones
Meeting rooms booked at less than 40% of available hours should be assessed for conversion to open collaboration areas. Sensor data showing actual in-room occupancy versus room capacity identifies consistently oversized and underused rooms.
Post-hybrid data consistently shows unmet demand for quiet focus space while open desk areas show excess supply. FM teams using heat maps to add focus pods see 22% satisfaction score improvement within 90 days.
Demand signal: Peak usage above 80% in 25% of available hours
Amenity and Support Space
Break rooms, print areas, and storage zones sized for pre-hybrid headcount are frequently oversized by 30% to 50%. Occupancy data confirms whether amenity space is appropriately sized or represents convertible floor area for higher-value uses.
Reassessment trigger: Amenity zone utilisation below 30%
Entire Floor Right-Sizing
When 12-month data shows consistent sub-40% average occupancy across an entire floor, the FM case for subletting, surrender, or floor consolidation is quantified. FM teams with occupancy data make these decisions on evidence; those without act on risk.
Right-sizing trigger: Sustained below 40% average floor occupancy
CapEx Planning for Fit-Out
Layout changes require CapEx for furniture, AV, power, data, and acoustic infrastructure. Oxmaint's rolling CapEx forecasting models zone conversion investment against projected cost reduction from improved space yield over a 3 to 5 year horizon.

From Space Data to Layout Decision: The Four-Step Process
1
Collect 90-Day Baseline
Sensor, booking, and badge data aggregated at zone level for 90 days minimum. Heat maps generated from week 1.
→
2
Identify Underperforming Zones
Zones below 40% average utilisation flagged automatically. FM cost per square metre overlaid to quantify the cost of each underperforming zone.
→
3
Model Conversion Scenarios
Oxmaint models hot-desk conversion, zone repurposing, floor consolidation, and subletting scenarios with projected cost reduction and CapEx per option.
→
4
Execute and Track Outcome
Post-conversion occupancy tracked against the baseline. Oxmaint confirms whether the layout change achieved projected utilisation improvement and cost reduction.
Space Planning: Reactive vs Data-Driven FM Approach
Decision Area
Data-Driven with Oxmaint
Reactive Without Space Data
Desk allocation
Hot-desk ratio set by 90-day data. Desk count matches actual peak demand with 15% buffer. FM cost per desk tracked by zone.
Desk allocation based on headcount assumption from HR. Actual occupancy unknown. Fixed desks maintained for occupants present 1 to 2 days per week.
Meeting room sizing
Room utilisation and group size from sensor data. Oversized rooms converted or subdivided based on actual demand evidence, not manager feedback.
Meeting rooms maintained at original design capacity regardless of booking utilisation. 34% no-show rate means rooms are empty for significant booked time.
Floor consolidation
12-month heat map confirms consistent sub-40% occupancy. Sublet or surrender decision supported by quantified cost reduction evidence for ownership group review.
Floor consolidation based on gut feel or cost pressure without utilisation evidence. Risk of consolidating active space or retaining genuinely empty floors based on wrong assumptions.
CapEx for fit-out
Zone conversion CapEx modelled against projected utilisation improvement and FM cost reduction. 3 to 5 year payback period confirmed before commitment.
Fit-out CapEx requested based on design concept without utilisation justification. No pre-conversion baseline means post-conversion outcome cannot be measured objectively.

QWhat data sources does Oxmaint use to generate space utilisation heat maps?
Oxmaint integrates with PIR and ultrasonic occupancy sensors, desk booking systems, and badge access platforms via API. All data feeds into zone-level records and generates heat maps at configurable intervals from 15 minutes to daily summary. Book a demo to see the sensor integration configured for your building stack.
QHow much utilisation data is needed before making a right-sizing or layout decision?
A minimum of 90 days of continuous zone-level data is needed to capture the full hybrid work pattern across seasonal and weekly variation. 12 months is recommended for floor consolidation or lease decisions to capture any seasonal variation in attendance patterns. Start free trial to begin capturing baseline space data from day one.
QHow does Oxmaint model the CapEx case for a space layout change?
Oxmaint's CapEx forecasting takes zone conversion cost inputs, applies them against projected utilisation improvement and FM cost reduction per square metre, and models the payback period across a 3 to 5 year horizon. The output is an ownership group-ready investment case with before and after FM cost comparison. Book a demo to see CapEx modelling for your specific zones.
QCan Oxmaint track post-conversion space performance against the pre-conversion baseline?
Yes. Oxmaint stores pre-conversion utilisation data against the zone asset record and automatically tracks post-conversion performance against that baseline. FM teams confirm within 60 to 90 days whether the layout change achieved the projected utilisation improvement and FM cost reduction target. Sign up free or book a demo today.
