"How do we co-design with them"

What our clients tell us.

You will recognise your situation if…

  • Employees discover the plans on delivery day.
  • The works council raises late objections that block the works.
  • Managers do not know how to arbitrate between open space and pods.
  • No user panel has been formally consulted.

Issues and impacts

Hidden cost

A project that is not co-designed generates 18 to 25% of post-delivery modifications according to <a href="https://www.arseg.asso.fr/" rel="noopener" target="_blank">ARSEG</a>. For a 850 m² fit-out, that represents 40,000 to 80,000 euros of rework (rewiring, relocated partitions, reassigned furniture). The overall timeline is then extended by 4 to 8 weeks.

Human risk

Nearly 47% of psychosocial disorders linked to the work environment stem from a feeling of not being consulted. Turnover increases by 12% within the 18 months following a poorly prepared move. HR directors then absorb a high social burden, often invisible in the project budget.

Reputational or regulatory risk

Consulting the works council is mandatory for any fit-out project that modifies working conditions. A rushed procedure exposes you to an obstruction offence and to an average delay of 6 weeks. For workplace managers, the internal image of the real estate department is lastingly damaged as a result.

How Kytom goes about it

Kytom structures co-design into three circles: a steering committee (HR director, workplace manager, management), a user panel of 8 to 15 representative employees, and workshops open to all teams. The method draws on the principles of design thinking and on observing real usage at the workstation. Each workshop produces a signed deliverable: empathy map, user journey, test mock-up. Our 11 agencies mobilise a dedicated space planner and facilitator. Across 1200+ projects, this approach markedly reduces post-delivery modification requests and strengthens team satisfaction at six months.

Our method

  1. 1. Diagnose

    In situ observation of usage over 2 weeks, presence counting, acoustic measurement according to the regulatory thresholds applicable to workspaces, interviews with 10 to 15 employees. Deliverable: a quantified diagnostic report, mapping of under- and over-used areas, and a summary of priority irritants validated by the steering committee.

  2. 2. Ideate in workshops

    Three 3-hour design thinking workshops with the user panel. Method: empathy map, weighted vote, paper prototyping. Deliverable: a prioritised functional brief, validated workstation/pod/collaborative ratios, and a report sent to the works council for formal information.

  3. 3. Test and arbitrate

    Immersive 3D mock-ups and an 80 m² pilot zone installed for 4 weeks. Employees test furniture, acoustics and lighting. Deliverable: a quantified arbitration grid presented to the steering committee, quantified feedback (5-criteria questionnaire), and a final plan signed by management.

  4. 4. Deliver and measure

    Works carried out in 12 weeks on average, change support (guided tour, co-written usage charter). Deliverable: satisfaction surveys at 1, 3 and 6 months, measured occupancy indicators, and a quantified adjustment plan if the gap exceeds 15% compared to the initial brief.

Cost and ROI

Additional cost of the co-design approach
30 to 60 euros excl. tax/m²
Workshops, facilitation and pilot zone included, i.e. 3 to 5% of the overall budget.
Participatory framing timeline
6 to 8 weeks before works
Integrated into the schedule, without extending the final delivery (12 weeks on average).
Typical ROI
payback in 18 to 24 months
Via reduced turnover, post-delivery rework and sick leave.

An anonymised field testimonial

"We dreaded co-design, but we experienced it as an accelerator. The trade-offs were settled upstream, the works council approved without reservation, and the teams took ownership of the spaces from day one."

Frequently asked questions

How many employees should be included in the panel?

Between 8 and 15 people representative of roles, seniority and status. Below 8, diversity is lacking; above 15, running the 3-hour workshops loses effectiveness. For 200 employees, 12 panellists are enough.

Does co-design extend the project?

No, if it is framed upstream. The 6 to 8 weeks of workshops fit within the programming phase. The total timeline remains 12 weeks on average for the works, compared with 16 to 20 weeks in the event of post-delivery modifications.

How do you combine co-design and works council consultation?

The works council is informed as early as the diagnostic, then formally consulted on the brief resulting from the workshops, in accordance with article L2312-8. The traceability of workshop reports strengthens the quality of the file submitted and speeds up the opinion.

What budget should be planned for the approach?

Allow for an additional 30 to 60 euros excl. tax/m², i.e. 3 to 5% of the overall fit-out budget. This additional cost is paid back in 18 to 24 months through reduced rework (40,000 to 80,000 euros avoided on 850 m²).

Is design thinking suited to SMEs?

Yes, from 30 employees onwards. For smaller structures, Kytom simplifies into two workshops and a panel of 5 to 7 people. The method remains valid; only the formalism is lightened to preserve agility.

How do you measure the success of co-design?

Three indicators: actual vs planned occupancy rate (target above 85%), satisfaction at 6 months (target above 75%), volume of post-delivery modifications (target below 5% of the budget). Kytom provides the dashboard.
