Commercial honesty is part of our method. Three configurations do not justify a full materials library pathway.
Area below 200 m² or single-material renewal. The five steps become disproportionate: the consultant time is not justified by the value of the trade-offs at stake. A short brief followed by a 90-minute workshop is then sufficient.
Traffic above 200 people/day. Polished concrete and certain wool carpets lose their relevance: the wear calculation projects refurbishment at 4-5 years, which invalidates amortisation over 8-12 years. We favour reinforced LVT or linoleum in these configurations.
Group charter imposing more than 70% of the finishes. The physical materials library ceases to provide differentiating value: a documentary audit on FDES sheets is sufficient, without a materials workshop.
Two points of attention complete this reading. A 20 × 20 cm sample does not reproduce the perception across a floor plate (a light shade can dazzle under 500 lux, a graphic pattern can tire after 8 hours at a workstation): we systematically recommend the 1:1 test. Certain premium references require a minimum order above 100 m², a constraint that we validate ahead of the supplier schedule to secure the project sequence.
