Diolch yn fawr, Llywydd. Following on from yesterday's debate on affordable housing in Wales, I would like to touch upon some important broader concerns that weren't raised in the debate. My concerns particularly regard the futureproofing of the increased supply of housing that we need and how we can build homes at volume that meet the needs and demands of future generations, particularly regarding energy efficiency. We are currently experiencing the struggle of modernising homes that weren't futureproofed when they were built originally, or indeed with any sense of adaptability in mind, and, ideally, we need to learn from history and not repeat this mistake. So, what support is being given to the sector so that they can build at volume the houses that we need to the standards that are going to be sustainable in the twenty-first century?
