Lots of dads buy houses for their kids. Not many buy their kids multi-million dollar waterfront estates.

Ira Trocki did. The prominent plastic surgeon and businessman purchased a brand new 10,000 square-foot home near Longport a year-and-a-half ago. Then he gave it to his daughter.

Problem was, she didn't want it.

"She said, 'Dad, it's gorgeous but it's way too large for us,'" Trocki says. "Even though she's married and has children it was way too big a house for them.

The dimensions of the house are jaw dropping. There are seven bedrooms, seven full baths and three full bathrooms. The great room has a 20-foot-high coffered ceiling and could pass for the lobby of a J.W. Marriott hotel. A walk-in closet is the size of a typical master bedroom and the shower chamber in the master bath could comfortably accommodate a dozen.

"Part of the second floor is like a separate house, with three bedrooms, two baths, a living room and a kitchen," Trocki says. "It's like a family compound."

The colossus stands on 2.6 acres at the end of a long gated driveway in Seaview Harbor, a bayfront community just across the Intracoastal Waterway from Longport and a stone's throw from where the Great Egg Harbor Bay meets the ocean. It wasn't even completed when Trocki contacted the owner and worked out a deal.

"I looked at that piece of ground years ago and thought, 'What a gorgeous area,'" Trocki says. "You have a view of the ocean and bay but it's very private."

Trocki put the finishing touches on the property before offering the estate to his daughter.

"I had my architect come in and make some changes," he says. "We put in the spiral staircase, changed the outside deck and added an Infinity swimming pool. And there's enough room for a three-or-four-hole golf course and a tennis court."

Size doesn't begin to tell the story. The property includes a sandy, 400-foot private swimming beach that extends all the way to the Longport Bridge. A large floating dock has plenty of room to park a luxury yacht or two, and the open ocean is just a couple of minutes away.

"We're going to put in a gazebo and we're thinking of putting in a lifeguard stand to give it the beach look," Trocki says.

The exterior of the house is made of white brick while the interior is a marvel of marble floors and travertine tile walls and counters.

The main kitchen has two large islands and two sets of upscale stainless steel appliances. A cappuccino maker is built into the cabinetry. The kitchen opens into a spacious lounge area with a two-story ceiling that overlooks the huge rear deck, the pool and the bay. A full bar with seating for at least 15 has refrigerated drawers.

An elevated formal dining room is separated from the great room by massive wood columns and features a hardwood floor and tall casement windows that look out over the bay. The first-floor master bedroom features a triple tray ceiling that has to be seen to be appreciated. In the master bath, an elegant whirlpool tub is sheltered by an ornate canopy supported by columns.

The shower chamber has two overhead shower fixtures, multiple jets and plenty of seating. The entire chamber is crafted in tumbled marble except for a curving wall made of glass blocks.

The second floor is accessible from two staircases and an elevator. It consists of two wings, each of which has its own full kitchen, bedrooms and bathrooms.

Amenities also include a three-car garage with a ceramic tile floor, heat and air conditioning.

"It has a high ceiling so you could fit six cars in there if you put in a lift," Trocki says.

When his daughter refused to accept his generous gift, Trocki considered moving in himself.

"I thought maybe my wife and I would like it so we stayed there for a few days," he says. "But she said it was just too large for the two of us."

So, the Trockis will stay put in their smaller bayfront home in Margate. Their mega-house is now on the market, listed for $5.5 million.

"It's a beautiful, livable house," Trocki says. "But I don't need a second home two miles away from my primary home."
