Hill Farm Estate was originally built in 1919 on 26 acres (110,000 m²) as the spacious and comfortable private home of Kreider and his family. The large Federal mansion is located less than a mile north of Lebanon Valley College on Route 934 in Annville PA. Hill Farm Estate sits in a quiet, scenic county setting with trees, gardens, benches, and walkways high on a hill overlooking the Annville community.

In 1982, the mansion was restored, a wing added, and became an assisted living residence, offering a beautiful homelike setting for retired individuals. In 2002 an additional residence wing was added. The home and independent-living center now offers 46 personal-care rooms for up to 55 residents and seven independent-living Carriage House apartments.

Inside the stately Federal era mansion, there is a comfortable parlor and lounges, antiques and period reproductions that complement the carefully restored architecture. The community is now called Hill Farm Estate. It is a personal care retirement residence and has Independent living units for seniors.
