My issue is that even with the Cheddington, which isn't as cheap looking as some places, still just uses pre-cast patterned concrete. It also tries to imitate the excess of Victorian era buildings, without applying the same level of attention to detail that made many of those structures so grand. I also can't tell exactly what it's trying to imitate specifically though, as it looks like a mishmash of styles.
There's nothing wrong overall with drawing influences from past generations of architecture, but a good architect will create something unique to this era using cues from the past, rather than just taking details but not really doing anything exceptional or different with them. Besides, I'm not really a fan of historicist buildings anyway so it's hard for me to relate with them. I'd rather see us embrace modernity and new styles that are of our time, rather than trying to recreate an imitation past.
The federal architecture of Russia that you're referring to, while overbearing, at least represents the era in Russia well. These modern historicist buildings don't really do that as much. Though again, interchange put it well, you get what you want from architecture. I love classic architecture and buildings, especially the Victorian stuff, but when it comes to our new stuff I'll take a clean modern design any day.
