Being from New England, living in a house from the 1600, 1700 or 1800's is commonplace, however, I've come to discover that San Francisco is a city of a different build. Since the majority of the city was destroyed during the 1906 earthquake + fire, it has a relatively new feel, which isn't necessarily bad. There are some beautiful homes (+ buildings) around the city and certainly no lack of character! The houses here are an incredible living history of architectural styles in the 20th century. Much like the weather changes from hill to hill, so does the architecture. Most of my current favorites are the ornate Victorian + Edwardian (think Painted Ladies) style houses around the city.
I'm hoping to take time and see the mid-century modern Joseph Eichler Diamond Heights neighborhood soon.
