In Stewart Brand’s book called How Buildings Learn he wrote that buildings are inherently conservative meaning they do not change. He believes that buildings should be made in an adaptive way so they can be susceptible to change and adaption. He listed out the components of a building by site, structure, skin, services, space plan, and stuff (site changing the least and stuff changing the most). I agree with his list because I feel like stuff (the interior objects in a building) change the most and the actual site rarely changes. Materials that change quickly would be technology materials in a building because technology is always changing. Materials that change based off fashion would be furniture and accents that go with furniture like the fabrics and pillows, also light fixtures change to keep up with what’s new. Some materials are resistant to change like marble floors for example or classic art pieces. These are timeless items that could remain in a building.
