The promise of a new idea.
Advisory and delivery for complex real-estate operations.
IDNéa supports property companies, investors and asset managers in framing, securing and executing their real-estate operations.
In-depth reading of existing fabric
Analysis of every building component: structure, materials, systems, uses and construction history.
Economic & technical arbitrage
Rigorous scenario comparison, comparative costing, intervention prioritisation by impact.
End-to-end management
Coordination of the entire transformation chain, from initial diagnostic to handover.
The value is already there.
It just needs to be revealed.
Every building is a coherent assembly of structures, materials, systems, uses and history. Our approach consists in analysing each component, understanding interactions, identifying hidden resources, and transforming without erasing.
From analysis to transformation.
Strategic diagnostic
In-depth building analysis, identification of constraints and latent resources.
Technical & economic optimisation
Scenario arbitrage, maximising the cost-to-value ratio.
Responsible transformation
Targeted interventions, construction sobriety, respect for the built heritage.
End-to-end management
Coordination of all stages, from diagnostic to handover.

Owner's read
Project management from a former client's chair.
IDNéa is led by Nicolas Idelot, who managed, invested in and delivered complex real-estate operations before founding the practice. Being a former principal, investor and client changes how a file is read.
In practice this means pragmatic trade-offs — conservation versus transformation, phasing, CAPEX prioritisation — genuinely held interfaces between designers, contractors, operators and users, and sustained attention to risk and execution. The only interest defended is that of the project and its owner.
An asset to optimise?
A project to structure?
IDNéa intervenes where value depends on an intelligent understanding of the existing.
