Today’s home is, at $11,800,000, the most expensive home currently listed on the MLS in the state of Kansas.
Located in Shawnee, about 10 miles outside of Kansas City, this contemporary European seven bedroom and 15 bathroom home is complete with a network of underground, water-filled tunnels designed for scuba diving.
Via a series of grottoes and pop-up holes, the tunnels lead to a 30-foot-deep outdoor pond, which is filled with statues, faux fossils and exotic fish.
The largest of the grottoes features a 30-foot waterfall, a heated swimming pool, a sauna and a wet bar for entertaining.
The owner, Lyn Shaw, built the house with her late husband, Dennis Langley, an energy executive and scuba enthusiast who also served several years as a speechwriter for then-Senator Joe Biden.
inspired by the legends of King Arthur and the design aesthetic of contemporary European mansions, this 17,755-square-foot property consists of a main house with three floors, seven bedrooms and 14 bathrooms as well as a guest house.
The home features several commercial-grade kitchens and a butler’s pantry.
The massive home includes a two-story office, library, conference rooms, a recreation room with billiards and a projection screen media center.
There is also a wine cellar, multiple wet bars, a heated garage and multiple living and entertaining spaces.
Coined “The Spirit of Avalon,” the mansion also features various imported antique and artistic elements, including hand-carved dragon doors, a pulpit from Salem, a Spanish hutch from the 1490s, stained glass windows, mosaics and more.

The 14.9-acre grounds boast trees, garden water features, statues and wildlife. Primarily built in 1993, a grotto feature constructed over a three-year period was implemented in 2000, followed by a two-story library in 2002. This incredible home is listed with Gary Hosack and his daughter, Katie Casey, both with Crown Realty, a Leverage Global Partner Member Brokerage.
