The promise of a new idea.
From feasibility to signed construction contracts.
IDNéa supports property companies, investors, asset managers and owners of medical centres. A full engagement connects intended uses, technical and regulatory feasibility, budget and the owner's decision.
Service area: the Greater South-West, within three hours of Bordeaux, and Paris.
Clarify
Understand the asset, intended uses, and technical and regulatory constraints.
Compare
Assess scenarios, programme and CAPEX estimates to inform the decision.
Contract
Coordinate design, tendering and signature of construction contracts.
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.
A full engagement to decide and procure the works.
Feasibility
Intended uses, asset condition, technical and regulatory constraints.
Scenarios and CAPEX
Compare programmes, options and budgets to support the decision.
Design and tender
Coordinate studies, prepare the tender package and assess bids.
Construction contracts

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 preparation of construction contracts.
