write about the changes in designs of building
Most current buildings are still designed from a linear perspective, neglecting future change and creating construction and demolition (C&D) waste during and at the end of their service life. The conception and design stages are crucial to ensure that buildings can support planned and unpredictable changes, in order to increase or maintain their quality of use.
However, designing buildings and building products to be reused and transformed is not yet integrated in current design practice.

  A building stock that can easily be maintained and adapted to future changes. Instead of prematurely demolishing buildings because they are unfit to meet changing demands, the actual service life of buildings will increase, which increases the added value for end users. In order to do so, building and product designers will need to take into account different future scenarios, using design principles supporting transformation, multi-use and disassembly. Facilitating this will lead to business opportunities for:
  
  • 
    designers: supporting technical designs for future retrofits;
    
  • 
    contractors: more construction and deconstruction projects within a shorter timeframe;
    
  • 
    facility managers: smooth maintenance and repair actions with no or restricted time delays.
    
• 
  Zero waste construction and deconstruction activities. Instead of landfilling and down-cycling of construction and demolition waste, as it is often done today within the EU, building components and materials will be reused and recycled for other useful applications, within or outside the built environment. Ideally, these continuous cycles can be repeated over and over again. To make this principle reality, building elements and product components need to be designed in such a way that they can be disassembled and reused, and that material quality and value are kept at the highest level possible.
