A day or two later, reader Paul sent me some flickr photos for some bad mansards. Thanks Paul! This is a view of Philadelphia's historic Broad Street.
A 3 story building, 2 stories of which is all crazy mansard roof. Is it old? New? Infill? A bad facade? I'm going with bad facade over a historic building. The windows level up perfectly with the building to the right. It would appear the shell exterior scales down the original size of the windows. That never looks good. Reminds me of this building in Soulard: click here.
