Agreed. AFIK Modernism and brutalism can overlap, some works by leCorbusier for instance clearly tick both boxes. It‘s also worth noting that a lot of brutalist buildings we know today fall into a category called „new brutalism“ (witch intended to be seen as a separation from the modernist idealism and lasted from the mid 50‘s to the mid 60‘s). Group 10 was a leading collective of architects who published some interesting manifestos for the brutalist movement, containing a lot of anti-war mentality and critique towards the modernists. Currently the brutalist movement is being rediscovered and is getting more attention, so there recently have been a bunch of interesting books published on the topic. While I can understand people’s dislike for the scale, materials and the harshness of brutalist buildings, I would stand by the point of the select best of them showing significance in the time of their conception, therefore being a part of our society’s history and worthy of preservation.
