Most of the main streets would have a capacity for automobile traffic, but it would be entirely possible to live and die in the city without ever setting foot in a car. Smaller streets would be car-free. Depending on how strong the local cycling culture was, there would be a network of bike lanes and paths that people could use to get around.
As for architecture, I don't like modern architecture that much, but I'm not picky. Buildings with a lot of brick are nice. There would have to be plenty of gardens and sitting areas to spend an afternoon in after a long day of work, to read a book, ejpoy a meal, or to wait for a friend.
