What Sedap Workshop does

Atelier Sedap is a French family-owned manufacturer of decorative plaster ornaments, architectural objects, and integrated plaster lighting fixtures, founded in 1968 by Charles Bohu and operated from a single production site in La Planche, near Nantes. The company works multiple plaster variants including traditional staff, reinforced plaster (plâtre armé), high-density plaster (plâtre haute densit), and a proprietary Vélistrat formulation, processing 90% pure gypsum from Paris basin quarries at 200°C without additives. Its core technology combines traditional French staff craftsmanship with LED lighting integration, a concept pioneered internally in 1982 by Benoît Bohu, and the catalog spans historical styles (Louis XIV through Napoléon III) alongside contemporary collections developed with external designers.

The product portfolio is organized into three sub-brand catalogs: SEDAP Ornements Architecturaux (cornices, ceiling roses, moldings, wall panels, niches, fireplaces), SEDAP Lighting (recessed domes, semi-recessed units, wall recessed lights, ceiling lights, wall lights, pendant lights, LED profiles), and Nuances et Matières (finishes and textures). The company sells through 100+ authorized resellers across France, 12+ European countries, and the United States (Miami, New York), complemented by direct e-commerce and online quote requests, and offers both catalog and bespoke custom work.

Revenue is generated through one-time product sales with quote-based, non-publicly disclosed pricing: orders under €5,000 HT require full upfront payment, orders ≥€5,000 HT require a 30% deposit with 30-day balance terms, and all custom/special orders require full payment regardless of size. Customer segments include interior designers and architects (primary), construction professionals and contractors (primary), and individual homeowners (secondary), with the company holding the EPV (Entreprise du Patrimoine Vivant) Living Heritage Company label since 2014.

Scale indicators2 records

Recent moves6 records

Expansion highlights4 records

Direct peers

• Marset: Spanish designer lighting brand with strong European dealer presence and designer collaborations. Direct peer for the lighting fixtures segment because it competes for the same architect/designer community on decorative ceiling and pendant fixtures.
• Orac Decor: Belgium-based manufacturer of decorative cornices, moldings, panel moldings, and indirect lighting cornices. Direct peer because it offers comparable architectural ornaments with integrated LED lighting across similar style families and B2B distribution channels.
• Baga (Manufacture Baga): French specialist in decorative fireplaces, moldings, and architectural ornaments, also historically a French craftsman (Établissements Baga). Direct peer because it competes specifically in the French luxury ornament and fireplace category with overlapping style coverage.
• Original BTC / Davey Lighting: UK heritage decorative lighting manufacturer offering plaster, bone china, and metal pendant and wall fixtures through a designer/specifier channel. Direct peer because of heritage positioning, decorative style coverage, and specifier-driven distribution model.
• Arstyl (by NMC): Premium decorative moldings and ornaments sub-brand of NMC, including indirect lighting cornices. Direct peer because the catalog overlaps directly with Atelier Sedap's ornament and lighting system product lines.
• Cosca Decoratiff: Spanish manufacturer of cornices, moldings, fireplaces, and architectural ornaments in polyurethane and plaster. Direct peer because it serves the same interior-decoration use cases across European markets with similar product categories.
• NMC (Nomaco): Belgian manufacturer of decorative wall panels, cornices, and architectural profiles used in interior decoration. Direct peer because it competes head-to-head in the decorative moldings and cornices category, including lighting-integrated products sold through dealer networks.

Regional players

• Luxalon (Hunter Douglas Architectural): European manufacturer of architectural interior products including ceiling systems and integrated lighting. Regional/adjacent peer because while it does not make plaster ornaments, it competes in the integrated lighting-into-architecture space across European commercial projects.

Broad incumbents

• Visual Comfort & Co. Large US-based decorative lighting company offering designer collections of ceiling, wall, and pendant fixtures. Broad incumbent because it competes with Atelier Sedap's lighting fixtures segment via extensive designer partnerships and dealer distribution, but does not specialize in plaster ornaments.
• Focal Point (Architectural Lighting): UK-based architectural lighting manufacturer offering recessed, trimless, and integrated architectural fixtures. Broad incumbent because it overlaps with Sedap's recessed lighting systems in commercial and high-end residential projects, though without the plaster ornament specialization.
