The Nightmare

The booking system said the building was full. A walk around said otherwise.

Ahead of a 2027 lease break, the Facilities and Workplace team faced a decision worth millions — and they had nothing but spreadsheets to justify it. Booking data, utilisation reports, and occupancy dashboards told three different stories. Operations were chasing gaps every quarter, hoping nothing had slipped through the cracks.

Ghost bookings were everywhere. Large meeting rooms sat dark while calendars claimed them as occupied. Cleaning crews mobilised for empty floors. HVAC ran on schedule, not on reality. Nobody had a single source of truth — so every space decision was a coin flip.

With a lease renegotiation on the horizon, that was no longer acceptable. 

In Their Words

We knew we had empty space. We didn't know how empty ,or what it was costing us. D-XPERT showed us exactly which rooms, which days, and which policies were bleeding money. Then it told us precisely what to change. That's not a report. That's a decision.

The DIREK Fix

DIREK deployed SpaceLens sensors across 140 desks and 3 meeting zones at the firm's London HQ. No cameras. No facial recognition. No personal data — ever. Just clean, anonymous occupancy signals, feeding live into D-XPERT™.

D-XPERT didn't produce another dashboard to ignore. It produced decision-grade recommendations — precise, costed, and ready to act on.

Here's what the data exposed, and what DIREK told them to do about it:

1. Ghost bookings quantified

Problem measured by room and behaviour

2. Auto-release rules deployed

No-shows eliminated through automated booking management

3. Oversized rooms split

61% of bookings were 1–2 people, rooms reconfigured accordingly

4. Booking policy rebuilt

Booking policy rebuilt around real utilisation data, not assumptions

5. Updated cleaning & HVAC schedules

HVAC and cleaning schedules adjusted to align with actual occupancy.

6. Permanent desks consolidated

From 140 to 83, with full peak capacity preserved

Impact

£777k unlocked from desk consolidation alone, rent, FM, and utilities
£11k additional from splitting the oversized meeting room into right-sized spaces
Cleaning and security hours cut to match real occupancy, not a rota built on guesswork
Midweek peaks and Friday lows mapped with precision: Tuesday hit 35.9% utilisation; Friday sat at 15.0%
Monthly governance loop now live, space supply adjusts continuously to hybrid demand
