The pilot projects developed in each country make it possible to address certain obstacles and are therefore essential. However, many European neighbours share an interest in reuse and it is essential to encourage the transfer of knowledge in order to massively expand these practices. A pillar of the Digital Deconstruction programme, the deployment of pilot projects in the partner regions fosters the confrontation with different types of buildings, such as museums (The Thermenmuseum in the Netherlands), train stations (Villeneuve Saint Georges station in France), historical structures (Hof Ter Laken castle and farm in Belgium), or social housing (Logements à Lomme in France).

Similarly, international collaboration helps to remove obstacles that may be faced in the future. Luxembourg and Belgium, whose small surface area creates problems for the storage of materials and waste, will, for example, work as a priority on facilitating on-site reuse and reducing delays, thanks to more efficient exchange platforms. On the other hand, France and the Netherlands face more regulatory and insurance barriers, and will therefore be the driving force in transforming legislation.

This collaboration also allows for valuable learnings and good practices already in place in neighbouring countries. The cultural diversity, both in the working methods and in the approaches adopted in relation to the different stages of maturity of the sectors, makes it possible, through the cross-border programmes, to capitalise on the strengths to accelerate the emergence of a mature and resilient market.

Moreover, the challenges facing the sector across Europe will require responses organised at local, national and European levels, and the sharing of knowledge within this type of project is a key development asset. Indeed, although the modes of organisation are different, international collaboration is a powerful catalyst for innovation and contributes to reflections on the sharing and replicability of tools and solutions.
