81st St Between West End Ave and Amsterdam Ave

Sitting in the heart of the Upper West Side, this segment of 81st Street cuts right across Broadway before continuing on along Theodore Roosevelt Park, and eventually Central Park. While the majority of the block is home to apartment buildings, getting nearer to the corners brings some commercial presence.

On the West End Avenue side, the Calhoun School sits with dominance on the corner. A uniquely-styled building (especially for a school), the architecture looks like something half-way between Frank Gehry and some Soviet-era institutional style. This could be explained by the fact that the top four stories were added on top of the 30-year-old structure in 2004.
