4. Enough is Enough
Compared to new construction, repair and renovation are generally more sustainable as they require less raw materials. However, current repair and renovation practices need to be overhauled. Of all the construction and demolition waste generated by the construction sector in Finland, a whopping 85% is caused by renovation and demolition and only 15% by new construction

In their current use, the terms ‘renovation’ and ‘repair’ cover a vast field of construction practices, from almost full demolition to high-quality restoration. These broad definitions blur the effect that these activities have on the built and natural environment, as well as the communities in which they take place. More precise terminology brings to light the differences within renovation practices, and therefore guides us to make more balanced decisions.
When changes are planned, we need to ask ourselves: “What is enough?” The necessary scale of renovation needs to be critically evaluated. In many cases the need for changes and alterations may derive simply from a craving for novelty. What changes in our attitudes towards existing structures, materials, and communities, if instead of pursuing maximum wow-factor, we strive for the smallest possible intervention? Architecture can play a crucial role in communicating that sustainability is not about “settling for less”, but about harnessing the full potential of what we already have.
