A Park City architect representing the ownership of the Claim Jumper building on Main Street last week filed papers at City Hall in anticipation of a major renovation of the historic building, a signal that the vacant property could someday reclaim its status as one of Park City’s grandest historic buildings.

Jonathan DeGray, the architect, submitted paperwork requesting officials review the designs against City Hall’s strict Old Town guidelines. A team of staffers is scheduled to review the designs during a Wednesday meeting. The Planning Department said alterations on the outside would include changes to the look of the windows and masonry work.

In a one-page letter to the Planning Department, DeGray provides a brief description of the plans for the Claim Jumper, 573 Main St. The letter said the blueprints envision the lower level becoming a restaurant or a nightclub. The main floor would become a lobby and space for special events, DeGray said in the letter.

Two apartments would be built in the upper two levels, according to the letter. Each apartment would occupy one floor, he said in the letter. In an interview, DeGray said the apartment on the third level could be as large as 2,800 square feet while the one on the second level could spread through 1,000 square feet.

Meanwhile, an application was submitted to clear up underlying lot lines at the site, a common request in Old Town. The Park City Planning Commission is scheduled to address the lot lines on Feb. 23, followed by the Park City Council.

“They’re preliminary. Right now, we’re trying to figure out what we can do,” said Billy Reed, a developer who represents the Claim Jumper ownership.

He said the changes to the outside of the building would be minimal under the plans.

The plans will likely be welcomed by various interest groups in Park City, with the Main Street businesses hoping the building opens again and Old Town enthusiasts anticipating the re-emergence of a highly visible historic building.

The Claim Jumper, one of the largest buildings on Main Street, sat abandoned for some time as the Arizona developer that owned the building considered redeveloping the property. The developer, though, scrapped its plans to open a boutique hotel in the Claim Jumper amid the recession. A subsidiary of the bank that was the lender on the building later took control of the building after the developer defaulted.

The bank put the building on the market, but it has not been sold. Reed said there is a possibility the bank could redevelop the Claim Jumper itself.

It has long been anticipated that a redone Claim Jumper would involve commercial space on the Main Street level and residential square footage on the upper floors.

The Microsoft search engine Bing operated a hot spot in the Claim Jumper during the Sundance Film Festival in January, believed to be the first time in years there were crowds inside the building.

In DeGray’s letter to the Planning Department, submitted shortly after Sundance, he indicates the Claim Jumper ownership wants to make structural improvements in an effort to meet building codes. Changes also would include removing columns on the inside. The letter says doing so would “free up the floor plan and allow for greater flexibility of uses.” It also says the ownership wants make the ceilings higher on the bottom level by digging two or three feet deeper.
