Upper King Street's first boutique hotel soon will rise.

A 54-room, four-story accommodation to be billed as the King Hotel will be built on a vacant lot at 583 King St. The hotel site is across the street from the twin Hyatt hotels and Midtown mixed-use facility that have been under construction since late last year.

The project will be headed by Trey Sedalik, a managing partner of locally based Prospect Real Estate Partners, and business partner Daniel James.

Sedalik said he's confident the hotel will stand apart from the slew of accommodations planned for the area.

"The Hyatt project will transform the area much like Charleston Place did to the 200 block of King Street in the late '80s," Sedalik said. "We're excited to be part of renewing a once-neglected area in an antebellum city known for preserving its charm and Southern hospitality."

He added that the target clientele is "a younger and more worldly demographic."

TKH Holding Group LLC, registered to Sedalik, purchased the quarter-acre lot for $895,000. Sedalik's plan to build a hotel on the lot has been in the works since 2012.

The Charleston Board of Architectural Review gave the project a green light last week, but its designers will likely have to tweak a few architectural features before construction can begin, city planner Tim Keane said.

The hotel also got a thumbs-up from future neighbors. The Cannonborough-Elliottborough Neighborhood Association sent a letter to the board last month in support of the project.

"After discussion and consideration of the proposed designs, our neighborhood association voted unanimously in favor of recommending conceptual approval to your board," Tim Muller, president of the association, said in the letter.

The small hotel will feature a rooftop pool and a parking deck with 14 spaces, about a fourth of the parking spots the hotel requires.

Keane said the hotel guests will use one of the two city-owned parking garages that are expected to rise in the area.

"We would prefer not to have all the parking on this site because it's a fairly compact in-fill on the set of businesses on Upper King Street," Keane said. "It would be better for those guests to use another public facility nearby."

The Midtown-Hyatt hotel across the street will include a city-owned parking deck, but Keane said it's likely that the King Hotel guests would park in a garage that's been proposed for a city surface lot at Morris and St. Philip streets. The zoning board has approved the 310-space parking deck, but it still must go to the architectural review panel for approval.

The King Hotel is the latest addition to a growing list of accommodations planned for the Upper King Street area. A 10-story, 185-room luxury hotel is under construction at 404 King St., next to Marion Square. Two more large hotels are planned for Meeting Street.
