The 25,000-square-foot home, nestled into a ridge near the intersection of Dover Road and Tufton Avenue, dates to 1985. A 1991 renovation added a gym with a full-size basketball court, batting cage, training room and locker room.
The home features six bedrooms, 10 full bathrooms and five half baths. There's a home theater with a box office, stage, candy counter and seating for 11, and an expansive kitchen designed to feed 100 guests.
There are two four-car garages. An outdoor entertaining area includes a heated pool, 10-person spa, kitchen and picnic area.
Ripken also designed and built a full-size baseball field on the property, which also features a 1-acre pond with a fishing pier and a biking and running trail.
Monument Sotheby's International Realty is the broker listing the property for Ripken.
Ripken purchased the land in 1984 for $215,000. The property is now valued by the state for tax purposes at just over $2 million.
