I grew up in East Liberty in 60s before moving to Carrick and their where a lot of Italians at one point and many where contractors and Home builders so it just makes sense they would build some unique homes well one went beyond unique to totally out there like UFO type out there.
Built in 1969 by Joseph Yacoboni it sits down the end of a long dead end road.and has been getting stares and visitors for many years.
Its now a AirBnB you can rent .

It was designed to resist extreme storms like Hurricanes and even Earth Quakes was even mentioned in Popular Science magazine in 75 and recently in Pittsburgh Magazine

But while it is a fun place one has to wonder.
There have been many UFO type sightings in the Sky all around that part of East Liberty and
could this UFO home be attracting them? like a Homing Beacon.
One never knows but if your looking for some unique place to stay or just visit look them up.
