The Ismaili Centre in Toronto, Canada has a certain Postmodern take on a traditional mosque, but in a way that actually looks and feels quite nice. It's clean-cut and contemporary, yet warm and inviting. The musalla (prayer room) feels open but not overly so, with a beautiful visual play between the warmth of the lighting and the blue of the sky. The only thing I'd like to see is a similar abstract take on a minaret off to the side of the "dome". This one was completed in 2014.
The Punchbowl Mosque in Sydney, Australia is very Neo-brutalist, but it's done in a way that looks visually striking both inside and out. It feels like it's striking a balance between modernity and tradition, personal and impersonal, unique yet familiar. It's hard to make concrete feel "personal", but I think they did a good job, especially through their incorporation of wood to help balance things. This one was completed in 2019.
