Atelier de l'isthme was referenced as the author of the “Rapport d'étude paysagère 2023” (landscape study report) published in the document library for the Centre Manche 1 offshore wind project area. The report formed part of the project’s environmental and use-related study set made available for the zone, alongside other baseline and specialist environmental investigations. In this capacity, Atelier de l'isthme provided landscape and seascape assessment work to support early-stage project development, helping to characterise the visual environment and sensitivities relevant to an offshore wind farm off the Normandy coast. The study scope typically includes defining the landscape/seascape baseline, identifying sensitive receptors and viewpoints, and producing visualisations (e.g., photomontages or visual simulations) to evaluate potential visibility and magnitude of change. It also supports the identification of mitigation measures and contributes to the evidence base used in environmental impact assessment and stakeholder dialogue. The source material did not state the contracting entity, contract date, or commercial terms; it only attributed authorship of the 2023 landscape study report to Atelier de l'isthme for Centre Manche 1.
