Every triennial break opens a window: renegotiate or relocate. We cost out both before you decide.
“Our lease is ending, we’re torn between staying and leaving, and no one has the figures to decide.”
A poorly negotiated renewal often costs 80 to 120 €/sqm/year too much in rent over 9 years. On 850 sqm, the cumulative gap reaches 600,000 € to 900,000 €, not counting recoverable charges and the Île-de-France office tax (24.01 €/sqm in zone 1 according to Légifrance 2024).
Nearly 38% of employees consider their work environment unsuitable. An ageing, un-renovated site accelerates turnover and hampers the return to the office, already limited to an average of 3.1 days per week in the tertiary sector.
The tertiary decree requires a 40% reduction in energy consumption by 2030. A building rated E or F exposes you to a costly action plan. Regulatory obligations on workplace lighting and ventilation also apply: a non-compliant site generates CSE reservations and an employment-tribunal risk.
Before the property decision, not after. We deliver four things: an audit of the site you occupy (technical condition, compliance, real capacity), a discreet market study of your micro-sector, a costed stay-vs-leave comparison on total occupancy cost, and a reasoned recommendation. The difference: these figures come from teams that build, not from a spreadsheet. No commitment, confidential, independent of any landlord.
Technical audit of the site (acoustics, thermal, utilities, compliance), occupancy count over 20 working days, manager interviews. Deliverable: a 25-page report with scoring out of 100 and a list of R4214 non-compliances. Timeline 3 weeks for an 850 sqm floor.
Definition of the target programme: ratio of workstations, meeting rooms, informal spaces, net usable area. Benchmark of the local market and identification of 4 to 6 real-estate alternatives. Deliverable: a framing note and comparative grid of renewal versus relocation over 9 years.
Layout sketch for the two selected scenarios, costing of tenant works per sqm (range 800 to 1500 € excl. VAT), post-renovation energy simulation, break-even calculation. Deliverable: a 40-page decision file presented to the executive committee with a reasoned recommendation.
Management of the chosen scenario as general contractor: lease negotiation or outgoing condition report, detailed 12-week schedule, trade coordination, handover and snagging. Deliverable: an operational floor at D+84 days and a maintenance log for the facility manager.
"The quantified 9-year comparison unlocked the decision at the executive committee. We renewed by negotiating 14 months rent-free and financed a complete renovation."
That’s the right time. A decision prepared 18 to 24 months before the break keeps your negotiating leverage; prepared under pressure, you lose it.
The market study is discreet and the diagnostic stays between us. Nothing leaves — not to a landlord, not to your teams — until you decide.
The diagnostic doesn’t replace your decision, it equips it. You leave with figures you can defend, whether or not you hand us the next step.
Yes, through an amendment, often in exchange for extending the firm term. The diagnostic tells you what that lever is worth in your case.
No: it requires a downward consumption trajectory, not a move. If the existing site is energy-hungry, a heavy refurbishment can rival a relocation — which is exactly what the diagnostic costs out.
The trio of general management, property management and facilities, with the works council informed early. You leave with a single file that serves the board decision.
