ARRS
The ARRS has been consulted for professional restoration, authenticity research, expertise and condition reports by national museums, government agencies, institutions and auction houses. Our international client base includes leading art dealers and private collectors worldwide.

At ARRS, we strive for sustainability in conservation through knowledge sharing, collaboration, and practical action. Our guiding principle is to view conservation not merely as restoration, but primarily as the long-term preservation of cultural heritage. Preventive measures play a crucial role: from climate monitoring and careful packaging management to promoting environmentally friendly materials and ultra-safe treatment methods. By minimizing interventions and focusing on sustainable techniques, we as conservators contribute to the future-proof preservation of nature, art, and heritage. In doing so, we safeguard both the physical integrity and the cultural value of objects - for present and future generations.

Our broad established experience working on Old Master paintings to Contemporary Artists includes:

  • conservation/restoration
  • scientific research
  • authenticity research
  • provenance and arthistorical research
  • advice on the condition and storage conditions
  • advice before and during purchase or sale
