‘Undertaking the complete renovation of a large apartment in Paris while living in Hong Kong during the Covid epidemic was a challenge. We were lucky to find Herold Design to meet this challenge with flying colors. Lionel Barde and his team respected our general views of what we wanted to achieve and, through long distance dialogue, oriented our choices particularly with regards to color scheme and the choice of materials. The execution was excellent down to the most minute detail. We are absolutely delighted with the result : an elegant and modern environment while preserving the Art Deco original architecture’

FAQ
As specialists in custom housing, our design is based on space optimization, volumetry, and the design of integrated layouts. We favor the use of noble materials, such as wood or natural stones, to bring lasting elegance to each interior design and renovation project in Paris.
Since 2010, luxury renovation projects have represented a significant part of our activity; our database includes an international clientele that is increasingly present in the Parisian real estate market.
As part of your luxury renovation project in Paris, the mission of an interior designer essentially rests on three key stages:
- The preliminary Conceptual and Technical Study: We carry out a preliminary technical study project (creation of existing plans, projected plan(s), demolition plan, masonry plan, electrical plan, carpentry plans, kitchen sections/elevations, bathroom sections/elevations, final 3D perspectives) allowing for the realization of your interior renovation. To help you better envision the final result, we also create final 3D perspectives.
- We deliver an initial site description by trade (demolition, masonry, electricity, plumbing, marble work, carpentry, kitchen, bathroom, painting, etc.).
- We provide you with a preliminary estimate of the budget and deadlines (no document is handed over at this stage).
- A mission order is contracted between the parties for the drafting of a detailed quote.
- We create a finalized mood board using catalogs and samples.
- We proceed with the selection of paint ranges, marble work, parquet flooring, waxed concrete, resins, carpentry, facades, lighting, mirror work, glasswork, plumbing fixtures, bathrooms and kitchens, equipment, veneers, fabrics, wall hangings, trimmings, blankets, rugs, accessories, framing, furniture, contemporary art, etc.
- We coordinate all the various trades.
- We update the technical plans throughout the construction site.
- We conduct weekly site tracking until final delivery.
- We ensure site tracking until final delivery, guaranteeing execution according to the norms and standards of Parisian luxury.
Our requirements focus on the rigorous mastery of circulation, axes, and symmetry to create fluid and coherent spaces. We favor clean lines for the sake of timeless visual harmony. This quest for balance and elegance is at the heart of every one of our interior design and renovation projects in Paris.
The study project is an essential analysis phase for carrying out interior works, and it revolves around the following steps:
- On-site visit and interview: An initial meeting is organized on-site with our interior designer to analyze desires and take technical constraints into account.
- Initial analysis of desires and technical constraints on-site: Our interior designer in Paris takes measurements of the existing space and creates a technical photo report.
- Design of technical plans: Our interior designer in Paris will first deliver several projected plan proposals, which will be discussed between the parties to lead to the production of a final projected plan. Based on this project
For our initial discussion to be constructive, a few elements are essential. In the case of a new acquisition, access to the apartment must be facilitated to allow our interior designer to take technical measurements. Similarly, a summary of all your desires should be communicated to our interior designer so that all your requests are fully taken into account. Finally, it is highly recommended to provide us with the floor plan attached to the co-ownership regulations if you have it in your possession. This architect’s plan provides information on the original technical elements of the construction, data that proves essential for the flawless execution of your luxury renovation project.
- Standard: ‘Minimal’ design and renovation, without significant remodeling of the existing structure.
- Custom: Fully custom design and renovation (remodeling of the existing structure).
- High-end: Custom design and renovation & high-end services (luxury renovation).
