At In Situ Heritage, conservation is guided by a profound philosophy: "Preservation before renewal". This principle underpins a commitment to meticulous, sensitive intervention that respects the intrinsic value and authenticity of every heritage asset. Our approach is fundamentally holistic, recognising that complex interior ensembles – whether designed as a unified whole or evolved through layers over time – are composed of numerous interconnected components. We consider all elements, from architectural features and decorative finishes to movable objects, ensuring that interventions on one part harmonise with the integrity of the entire ensemble.

Critical Engagement and Cultural Sensitivity:

We engage critically with diverse conservation approaches, drawing upon best practices both locally within the UK and internationally. This includes a deep understanding of various theoretical frameworks and practical methodologies, allowing us to select the most appropriate and effective strategies for each unique project. Furthermore, In Situ Heritage operates with utmost sensitivity when dealing with material heritage from different cultures. We recognise that heritage objects carry profound cultural significance and diverse interpretations, and our work is always conducted with respect for their origins, histories, and the communities connected to them.

Integration of Research, Education, and Engagement: 

Our conservation work is not an isolated practice; it is strongly integrated with our research, education, and public engagement services. Every conservation project benefits from rigorous historical and material-technical research, which informs our understanding and guides our interventions. We are committed to sharing this knowledge, incorporating educational opportunities for interns and learners, and developing public engagement initiatives that illuminate the conservation process. This ensures that the stories embedded within the material heritage are not only preserved but also understood, appreciated, and made accessible to wider audiences.

Minimal Intervention: 

Visually disruptive damage within an interior can be distracting. While extensive restoration is sometimes the only option, it is often not necessary. In Situ Heritage employs the "Ontstoren" principle, which involves small, precise interventions to treat the most noticeable signs of ageing and damage. This method offers significant benefits: it prevents the interior from acquiring an "over-restored" or "too new" appearance, thereby maintaining its historical character. Furthermore, it is frequently more budget-friendly than a large-scale restoration. "Ontstoren" is always a customised service, as every interior and its occupant are unique, ensuring that the possibilities are explored collaboratively for each specific situation.
