Concrete is strong and imposing and emotional. It feels authoritative and cold. A warm building feels like it has deliberately undermined its own status to feel welcoming and feels fake. A brutalist building doesn't lie. It is a massive concrete edifice containing a large space within.
It also weathers in distinctive ways. The water stains are like seniority, telling me the building has and will last forever. A big glass skyscraper feels replaceable and new, like it's disposable and will be replaced in a few years.
I get a lot of hate for this but one of the benefits of a concrete house is the ability to throw stones.
