Paris remains the European epicentre of high-end renovation. With new environmental regulations, rising budgets, and increasingly exacting client expectations, 2025 is reshaping the practice of luxury interior architects. Here is a clear, well-sourced and genuinely practical overview to help you prepare your project, with a particular focus on the approach of Laurent Galle, an interior architect widely recognised for his residential and hospitality work at the highest level.
Key figures for 2025
- Rental ban on G-rated properties: since 1 January 2025, properties classified G under the French Energy Performance Certificate (EPC) can no longer be let. This is accelerating the pace of energy renovation across Paris’s existing housing stock.
- Median renovation budget in France: up 33% over three years, rising from €15,000 (2020) to €20,000 (2023-2024), with kitchens and bathrooms consistently the most costly areas.
- VAT on works: 10% for the majority of renovation projects, 5.5% for energy improvement works. From 2025, a simple mention on the quote or invoice is sufficient to benefit from the reduced rates, replacing the former Cerfa attestation.
- Renovation costs in Paris (high-end segment): full renovations are frequently priced between approximately €1,500 and €3,200 per square metre, with costs rising further depending on finishes and site constraints.
- Paris bioclimatic local urban plan (PLU): adopted at the end of 2024 and coming into force in 2025, this new framework strengthens environmental requirements and introduces enhanced protections for retail and craft businesses.
What changes in practice for your high-end project
The acceleration of energy renovation
Energy efficiency has become a condition of rental: properties rated G can no longer be let as of 1 January 2025. For investors and landlords, energy auditing, insulation, ventilation, HVAC systems and the selection of high-performance materials are no longer optional considerations. Interior architects now integrate technical routing as standard from the earliest design stages, covering internal insulation, joinery, and the treatment of thermal bridges.
New rules under the bioclimatic urban plan
The Paris bioclimatic PLU demands a more detailed reading of regulatory constraints: preservation of ground-floor retail, environmental requirements around permeability and greening, and a careful balance between permitted uses. For interiors, this affects planning permissions, the management of external technical units (heat pumps, air handling units), and changes of use. Working with an interior architect who is well-versed in the PLU protects both timelines and compliance.
Simplified VAT and billing
On the administrative side, there is welcome news: a simple mention on the quote or invoice now replaces the former attestation in order to obtain VAT at 10% or 5.5%, depending on the nature of the works. This saves time for both studios and clients alike.
Circular economy and the construction waste management scheme (REP PMCB)
For a full high-end renovation in Paris, budget approximately €1,500 to €3,200 per square metre, and potentially more for exceptional finishes such as solid stone, made-to-order joinery, marquetry, or premium home automation systems. Wet rooms and kitchens remain the principal cost centres.
Fees: an architect or interior architect typically charges between 8% and 15% of the total works budget for a full service covering design, consultations, site management, and handover. On larger budgets, the percentage may decrease incrementally across agreed thresholds.
Useful benchmarks: specialist platforms publish detailed case studies and pricing ranges by service level. These are helpful for establishing an initial budget framework, but are no substitute for a precise tender document and a competitive multi-contractor process.
Heritage, haussmann and planning permissions: navigating without missteps
In Paris, protected heritage zones and the surroundings of listed historic monuments can subject even internal works to a prior declaration. Instruction periods, often running from two to four months depending on the type of authorisation, must be factored into the project timeline from the outset. Haussmannian signatures, including cornicing, parquet floors, and original joinery, call for reversible interventions, like-for-like restoration, and materials compatible with the existing fabric of the building.
Expert focus: Laurent Galle's approach
Interior architect Laurent Galle is distinguished by a restrained and timeless design language, in which materials, solid woods, natural stones, technical textiles, and light work together to structure the space. His Paris projects are built around:
- Optimised floor plans: considered circulation, integrated storage, and the careful attention given to the home’s key spaces, the kitchen and the principal suite.
- Thermal and acoustic comfort developed in close collaboration with specialist engineering consultants, covering insulation, high-performance linings, and intelligent solar shading.
- Made-to-order design: joinery, ironmongery, and fully scripted lighting atmospheres.
- Full regulatory compliance: the bioclimatic PLU, EPC requirements, insurance, and health and safety coordination are all integrated from the design phase, securing both costs and timelines.
This “architect as conductor” approach meets the expectations of Parisian owners: uncompromising quality, respect for the intrinsic character of the space, and a handover without unwelcome surprises.
How to choose your luxury interior architect in Paris
- Verifiable references in Parisian apartments, including Haussmannian properties, and private mansions.
- A clear project methodology: master programme, defined milestones at each design stage, site meeting minutes, and a structured approach to managing the unexpected.
- Regulatory fluency: the bioclimatic PLU, EPC compliance, any constraints relating to listed buildings or protected areas, planning requirements, and applicable VAT rates.
- A trusted ecosystem of contractors: high-calibre artisans, premium suppliers, and the capability to source responsible materials and construction waste management partners.
- Budget transparency: itemised estimates by trade, design alternatives, clearly detailed fees (typically 8-15% for a full service), and a rigorous approach to managing variations.
Key takeaways
In 2025, delivering a luxury renovation in Paris means reconciling aesthetics, performance, and regulatory compliance. The rules are tightening, with EPC requirements and the bioclimatic PLU setting a higher bar, but the wider value chain has professionalised in step: VAT has been simplified, construction waste management is now properly structured, and costing tools have become considerably more robust. An experienced interior architect, such as Laurent Galle, makes all the difference: vision, rigour, an established network of trusted contractors, and the assurance of a delivered result.
