We develop sustainable conservation strategies for art and cultural assets and can manage your collection on a short or long-term basis. Holistic, innovative and reliable.

Our team combines conservation with art historical expertise and many years of experience from working with public and private partners.

We provide independent advice: from bespoken concepts for individual artworks to full-scale management of large collections.


We support museums, collections, estates and archives as well as artists in securing, maintaining and assessing their collections. Depending on the respective need, we can expand our team with specialists from our network to provide professional support.

Your advantage: We provide you with a single source that can take care of everything.


The core competence of our consulting:

  • Art historical and conservation evaluation

  • Strategic planning for long-term preservation

  • Analysis for the optimization of storage conditions

  • Formulation of standards for acquisition and handling

  • Preparation of specifications for digitization projects

  • Inventory and metadata registration

  • File analysis and forensic examination of data carriers


Our proposed solutions are based on the respective framework conditions and thus enable a realistic implementation of the required measures.

During the implementation phase, we support the project participants. In addition to written reports, we also offer in-depth workshops for you and your employees.

In the case of more extensive transformation projects, we are also happy to support the process as moderators.


As reliable partners, we also ensure long-term maintenance and can take over the execution of specific collection management tasks as an external service provider.

Our main areas of expertise are:

  • Art historical processing of convolutes

  • Arrangement of details and communication for exhibition conditions

  • Accompanying loans and new installations

  • Regular condition checks / reports

  • Coordination and supervision of complex acquisitions (purchase agreement)

  • Organization of digitization projects


Interdisciplinary knowledge transfer for the preservation of cultural heritage is an important task for us at Preservation as a Service. Embedded in the international research community, we regularly contribute articles on preservation theory and practice to renowned publications. In addition to academic teaching, we offer seminars for practitioners on specific tasks, e.g., long-term archiving of audiovisual cultural property or the processing of artists’ estates.

Please find below a selection of our contributions. We will gladly send you a reference list of our previous projects upon request.

Our unique feature is the combination of conservation consultancy and art historical expertise in one team. Thanks to our many years of experience in the practice and theory of preserving cultural heritage, we have been combining the perspectives of technical know-how and the latest specialist research in "Preservation as a Service" since 2019.

When developing long-term preservation concepts for contemporary art, this interdisciplinary collaboration is indispensable. In this case, the decision-making process involves consideration and assessment of both material and conceptual aspects of the work, according to ethical preservation guidelines.

With our combined expertise, we bring together these diverse perspectives in a structured process to ensure the comprehensive consideration of all value-relevant characteristics.
