Move over Salt Lake City. Lehi is about to get the state's tallest building -- a 450-foot hotel with the Frank Gehry touch.

Comprising up to 300 rooms, the 220,000-square-foot, 45-story hotel and convention center in Lehi will supplant the state's tallest building to date -- the LDS Church Office Building in downtown Salt Lake, which stands at 435 feet, and the second-tallest building, the Wells Fargo Center, at 422 feet.

Details of the 85-acre multi-billion-dollar mixed-use project near the Point of the Mountain, which is being designed by world-renowned architect Frank Gehry, were unveiled Wednesday afternoon by Brandt Andersen, a 29-year-old Provo entrepreneur and majority owner of the NBA Development League for Utah.

Inspired by the natural architecture found in Utah's slot canyons such as The Narrows at Zion National Park, the Lehi project will include a signature 500,000-square-foot, 10,000-seat arena, an amphitheater, 3.6 million square feet of residential space or 2,500 condo and multi-floor residential units, and 1.12 million square feet of retail space. The project also includes a boating lake, a wakeboard cable water park and 61 acres of open space.

Funded by Andersen, the project hopes to attract action sports-type tenants, high-end restaurants and upscale retail stores. A timeline for its construction hasn't been determined because that depends on how quickly the property can be rezoned by Lehi City for sports and entertainment.

Just how will a Frank Gehry-designed community relate to Utah?

"We have some of the world's greatest natural architecture in Utah. Our buildings will reflect that. Along the walkways, we will have buildings hovering over the water or recess back to reflect the canyons' structure," he said. "As you look at the development, the first thing that strikes you is the openness of it. The majority of parking will be underground in order to leave more than 70 percent of space open."

Business people and government leaders got a glimpse of Gehry's vision Wednesday, albeit a sketchy one as the wooden and translucent glass blocks representing homes, retail stores and a hotel on the model don't represent the final artistic product. The model has undergone 30 different designs so far, but actual building specifications and designs aren't available yet.

"Not every building will be iconic," Andersen said. "The hotel, the arena and the amphitheater will be iconic, and these are spliced throughout the site to grab the eyeball."

"Before the Guggenheim was built, Bilbao has centuries of history, and hardly any buildings that are postmodern," Andersen said. "But Gehry took the lay of the land, and created something Bilbao's residents initially thought strange but later became very proud of."

Lehi Mayor Howard Johnson, who was at the project's unveiling Wednesday, says he believes the project will be a "beauty spot" and "an international draw."

He said the city has seen a surge of new projects converging at the Point of the Mountain in recent years because "both Salt Lake and Utah counties are growing together at this area."

"We have Thanksgiving Point, Cabela's, Micron, the Terrace at Traverse Mountain that's literally a city in itself with 30,000 to 40,000 people, a possible lifestyle center and now, this, a Frank Gehry-designed project. This is the last major location to grow along the Wasatch Front," Mayor Johnson said.

But all this growth presents a problem, he said. "How do you put two potential major malls, a manufacturing plant, Cabela's, and potentially up to 40,000 more people in an area fed only by SR 92 and a sidewalk cow trail?"

To handle the potential surge in traffic, Andersen is in talks with the Utah Department of Transportation on the possibility of building an additional off-ramp more than a mile north of SR 92 or the Highland/Alpine exit.

For Joel Racker, president and CEO of the Utah Valley Convention and Visitors Bureau, the growth can't come fast enough. "We want to know how soon we can sell the project to trade shows, conventions, athletic events, water sports, wakeboarding events, corporate associate type meetings. It's hard to sell a place when we don't know when it'll be built."
