A 22-room Neoclassical mansion in Wallingford, Pennsylvania, built in 1921 for industrialist Howard H. 15 million. The six-bedroom property, known as the Houstonia mansion, sits on five acres that include a former greenhouse, extensive lawns, and woods. The estate is bounded by township parks and Ridley Creek.

The home features a bluestone terrace with a Juliet balcony and two-story portico. Inside, preserved elements include hardwood floors, hand-carved millwork, custom wainscoting, pocket doors, and dual staircases. A light-filled living room with a soapstone hearth fireplace connects to a sunroom.

The dining room also contains a soapstone hearth fireplace. A gourmet chef’s kitchen includes a butler’s pantry. The main stairs in the entry hall lead to a large Palladian window and split into two curving stairways. The office contains Houston’s original hand-painted safe built into a custom closet.

A 2,500-square-foot detached carriage house with three heated garage bays sits on a separately deeded parcel. The two-bedroom residence includes a great room, eat-in kitchen, family room, and private deck. A guest suite occupies the third floor along with bonus rooms, walk-in cedar storage rooms, and a billiard room currently used as a family room. The primary suite contains a dressing room.

The property lies near the Philadelphia International Airport and commercial centers in Philadelphia and Wilmington. It also provides access to recreational areas including the New Jersey shore, Delaware beaches, Pocono mountains, and Chesapeake Bay.
