Habitat 67 in Montreal is a Brutalist concrete building (many cubes) that is generally well-liked and has been a desirable place to live for 50 years.

Its perhaps too large of a building for my liking, and it feels a little bit "minecraft" with seemingly unsupported cubic shapes, but it also has a nice focus on human scale details that make it actually interesting to be in and around.
