Hybrid working and the office concept: rewriting the brief.

    By Mark van den Berg

    Hybrid working didn't kill the office, but it did rewrite its purpose. A headquarters designed on a pre-hybrid brief — full-occupancy seating, traditional ratios, default desk-per-person — is almost always the wrong building at the wrong cost. This article describes the implications for the office concept and where boards typically misread the shift.

    What the office is now for

    In a stable hybrid pattern, the office is primarily for what the home isn't good at: collaboration, mentoring, client contact, deep team work, and the cultural infrastructure that gets thin over distance. Routine focused work largely moved to home and is unlikely to return at the scale it had.

    That shift implies a different mix of space: fewer rows of desks, more rooms of different sizes, more shared spaces designed for actual collaboration rather than the appearance of it.

    Sizing on usage, not headcount

    The most consistent error in post-hybrid sizing is using headcount as the input. Headcount predicts the maximum theoretical occupancy, not the actual one. Across knowledge-economy organisations in the Netherlands we see average weekly office occupancy of 35–55%, with predictable peaks on Tuesday and Thursday.

    Sizing for the average over-builds; sizing for the peak over-builds further. Sizing strategically means choosing a target peak coverage and explicit overflow strategy — that's a strategic choice, not a capacity calculation.

    The new ratios

    Post-hybrid headquarters consistently shift the ratios:

    • Desk-to-FTE ratio of 0.5–0.7, sometimes lower for client-facing teams.
    • Significantly higher share of meeting space — bookable rooms, project rooms, collaboration zones.
    • Dedicated focus space for the in-office hours where deep work still happens.
    • Larger and better social spaces, treated as infrastructure rather than amenity.
    • Client and event space sized to the new role the office plays in pipeline.

    Policy and concept need to match

    An office concept built for hybrid only works if policy is consistent with it. A 50% desk ratio with an implicit five-day-in-office expectation creates a crisis on Tuesday and an empty building on Friday. Policy precedes concept, not the other way round — and the board needs to settle the policy before the design brief is signed.

    This is the moment where change management and concept overlap most directly: the building reflects the policy and the policy is led from the top.

    What to stop copying from pre-hybrid playbooks

    Three pre-hybrid defaults that no longer make sense: assigned desks at scale, a 1:10 meeting-room-to-desk ratio designed for an occupied building, and minimal investment in collaboration infrastructure. Each of them was rational for the old occupancy curve and is now structurally wrong.

    Frequently asked questions

    Will hybrid stabilise or keep shifting?

    +

    Most evidence points to a stable pattern of two to three days in office for knowledge work, with cyclical variation. Designing for that range is more defensible than designing for either extreme.

    How do you handle the Tuesday-Thursday peak?

    +

    A mix of policy (encouraging spread), space (bookable overflow zones), and culture (acceptance that not everyone gets a desk at peak). Sizing for the peak in m² is almost always the most expensive option.

    Should executives have fixed offices in a hybrid concept?

    +

    Almost never. Fixed executive offices in a flex environment signal that hybrid applies to others, and that signal undermines the entire concept.

    How long after move-in should occupancy stabilise?

    +

    Six to nine months. If patterns are still shifting after a year, the policy and concept are usually not yet aligned and need explicit board attention.
