What do you do after buying Pinellas County's largest mansion?
You make it the biggest in Tampa Bay.
The already swollen estate on Old Keystone Road in Tarpon Springs is about to grow to 44,954 square feet, about the size of the average Publix supermarket.
Plans for the mega-mansion, highlighted in building permits, might make Robin Leach blush.
The ground floor expands by 5,537 feet to house a bowling alley, museum, staff lounge, spray-tan room, massage room and wine-tasting room. An office, beauty salon and several his-and-her bathrooms need 5,259 square-feet. A nanny/guest room on the second floor will require 2,138 square-feet — bigger than the size of an average house.
The 13,000-square-foot expansion includes new elevators and separate rooms to store luggage, golf clubs and museum artifacts, which is in addition to the museum.
Texas-based Lake Ridge Trust bought the house last January for $8 million from former NBA player Matt Geiger. He originally listed the six-bedroom, eight-bathroom mansion for $20 million in 2007. Amenities included a shark tank, a 330,000-gallon swimming pool and a rock-climbing wall.
The estate sits on nearly 28 acres and includes a 5,000-square-foot guest house.
Several people connected to the trust have declined numerous requests for comment.
The contractor, Lithia-based Bartlett Custom Homes, signed a confidentially agreement not to talk about the project, an official said.
The mansion will top RV king Don Wallace's 40,000-square-foot estate on the shores of Lake Thonotosassa and New York Yankee star Derek Jeter's 30,000-square-foot palace on Davis Islands.
The county estimated the cost of the expansion at $1.6 million, but that was using average construction costs.
A luxury expansion of this sort will cost much more than that.
The county approved the plans last week. The cost of just the permits: $9,621.
