L'Atelier Le Castel, in La Chaux-de-Fonds (canton of Neuchâtel, Switzerland), works in creation, decoration and restoration, old and new. His technical and artistic skills cover a rich spectrum of styles and expressions. He masters techniques such as painted canvases, faux wood, faux marble, trompe l'oeil...

La Chaux-de-Fonds, a Unesco World Heritage Site since 2009, provided fertile ground for the development of the Atelier, which took part in major restoration work for:
- the Ancien Manège (faux marble and decor, Art Nouveau style)
- the organ in the Conservatoire concert hall (Baroque style)
- numerous painted stairwells, including that of the building
  Serre 28 (paint trade).

Over the years 2000 - 2010, L'Atelier has completed several large-scale mandates: in particular, it has designed and carried out the complete decoration of prestige liners (MSC cruises), using different themes (see portfolio).

High-end watch brands have entrusted l'Atelier with the enhancement of their exhibition stands, showrooms, reception lounges... And, attentive to the quality of their living spaces, private clients have also called on the Atelier's creativity and professionalism.
