Orbis Conservation offer a comprehensive service in the conservation and restoration of all three dimensional art works and architecture. Founded in 2013 by Hans Thompson and Maxwell Malden, Orbis are a small team driven by a thorough commitment to the preservation of cultural heritage and to maintaining the skills of previous craftsmen and artists.


Working with Orbis to conserve, record and re-house our Neolithic monuments, the Calder Stones, has been a pleasure. From the start, the team have taken a positive, proactive and consultative approach, friendly with our volunteers and understanding of our needs and constraints. The standard of care and work with our priceless artefacts has been exemplary. We would heartily recommend Orbis.
