Today, we are increasingly aware of the environmental harm caused by building with concrete. One approach to using it more sustainably is to repurpose existing buildings, exposing their structural elements and integrating concrete into the surface. While concrete can sometimes give off an austere or overly cold vibe for a residential space, wood provides an alternative to soften this impression, transforming what might seem industrial into a warm and inviting home environment. By doing so, they can impart distinct qualities to the same space through the interplay of their textures and colors, evoking different sensations in occupants. There are various ways to explore the interaction between these materials, and we illustrate some of these possibilities through six Brazilian apartment examples.
