Here are the videos we watched in Studio with regard to materials and texture. Have a think about the impact using one material can have upon an occupant over another material. What sort of experience do you want to elicit? Is it warmth, comfort, movement, anticipation, etc. etc. How might you conjure these feelings with different use of texture? This is the point of the abstraction of your 36 descriptive words.
Texture in architecture can be a powerful force. Think about what I spoke about the Berlin Memorial to the Murdered Jews of Europe.. the sense of fear, change, anxiety, loss, disorientation, instability. These emotions are in part a result of the form and configuration but also of the textures and materials. The smooth bare concrete blocks from a distance appear the same and repetitive, perhaps like a crowd of people, but on closer inspection, each block is a slightly different size, shape and angle, furthermore, some have developed cracks, chips, blemishes... they are all individual - this is a very powerful notion when you consider what it is a memorial for.
Think about how a different material used at the Berlin Memorial would perhaps not be as successful at communicating the intended message... Like pink blocks?
