Pennlyn is far from a cookie-cutter neighborhood. It is comprised primarily of detached, single family homes built during virtually every decade of the twentieth century. The majority of homes range from 2 to 5 bedrooms with 1 to 3 bedrooms and range from 1,000 to more than 5,000 sqft. Most of the homes have basements. Some have garages.
The neighborhood is generally bounded by railroad tracks, Gwynedd Avenue, Township Line Road and Penllyn Pike.
