1. LLI in 2025: the return of a product, the launch of a model

The disappearance of the Pinel scheme opens up a gap. LLI (logement locatif intermédiaire - intermediate rental housing), relaunched by the government via targeted tax measures (10% VAT, property tax credit, extension to family SCIs, etc.), is settling in as a transitional solution.

But in practice, the LLI is not a unified system:

• it is neither social housing nor open market,
• it is based on capped rents, but without any obligation to obtain certification,
• it is attracting new operators (private developers, property companies), but the historical social landlords are gradually withdrawing from it, in the absence of a clear economic framework.

The result is a blur: an attractive tax product, but with no guarantee of structural value.

2. Is an asset sustainable if it is neither proven nor certified?

In the majority of LLI transactions analysed by ARKORIS over the past two years, we have observed the same characteristics:

• Clear financial objectives (profitability, controlled cost per m², limited carrying costs);
• Partial efforts on thermal engineering (RE2020, sometimes Effinergie);
• Little or no acoustic, fluidic or biodiversity strategy;
• No formal ESG trajectory, particularly in the operating phase.

📌 Yet an asset not aligned with long-term environmental trajectories will lose value - not necessarily at purchase, but at resale, refinancing, or in mixed tenders.

3. Three operational risks for promoters

❶ Delayed regulatory obsolescence

Thresholds are changing: what is compliant in 2025 will not necessarily be in 2030. Especially if local authorities tighten up their specifications.

❷ Incompatibility with the requirements of responsible investors

Real estate companies and insurers integrate sustainability criteria (biodiversity, low-carbon, usage performance). A project that cannot be traced is out of scope.

❸ The impossibility of claiming an environmental commitment without proof

A project without independent audit, certification or data will not be able to claim any extra-financial leverage.

4. What ARKORIS offers: engineering, structure, demonstration

ARKORIS does not sell a label. We don't make promises. We organize a structured response, integrating three operational levels:

🔹 ARKEMEP

Technical design office - thermal, acoustic, fluids → Dimensioning, traceability, real environmental planning.

🔹 ARKENOR

Environmental project management - NF Habitat HQE, BDM, infiltrometry, ecological engineering → Support for certifications, control of regulatory interfaces.

🔹 IRICE

Independent third-party certifier - Effinature and Biodiversity Performance Score standards → Verification, auditability, external recognition.

📌 It's the articulation of these skills that makes a project credible, not a mention on a brochure.

5. How can we make LLI an asset for the future?

We have identified three simple levers for property developers:

① Define a proof trajectory right from the competition or PC phase

No sustainable strategy without indicators. No indicators without method.

② Combine engineering and certification for efficiency, not extra cost

Certifying what is already intelligently designed doesn't cost more. It simply adds value.

③ Structuring ESG communication around audited elements

When it comes to LLI projects, marketing is no longer enough. Investors and local authorities demand proof.

Conclusion

LLI can become a pillar of sustainable residential supply. But only if it goes beyond the strictly fiscal sphere and embraces a logic of demonstrated value. At ARKORIS, we work with developers and landlords who want their projects to be sustainable - not just compliant.
