Changing Skyline: Philly housing authority brings suburban mentality to Ridge Avenue

As the name implies, the Philadelphia Housing Authority's speciality is housing. Though its designs have been a mixed bag - from the dystopian Schuylkill Falls towers to the gentle, rowhouse-scale MLK houses - the agency has ensured that thousands of low-income families have a basic roof over their heads. It might surprise some to learn that PHA is the city's biggest residential developer, the landlord for about 81,000 people.
