UPDATE:

I just received an email from the developer. Apparently, B&T was incorrect in what it reported.

Eastat is developing 250,000 sf of office and 174 parking spaces. We are not touching the historic Jacob Wirth building at all and it will be preserved, protected and remain operational. The project you describe was the pervious proposal by Weston Associates in 2006.

Thank you, Mr O’Marah, and good luck!

Earlier:

The Boston Business Journal reported today that the parking lot will be sold by the owner of Jacob Wirth’s and developed by the new owners.

Further:

[The developer] plans to build 250,000 square feet of office space, 2,000 square feet of retail space and 174 parking spaces at 45 Stuart Street. The building will have entrances on both Stuart and LaGrange streets with the main entry featuring a two-story indoor public winter garden with a cafe. The developer is also proposing six roof gardens to manage storm water and create an environmentally friendly project.

Even earlier:

According to Banker & Tradesman, a new developer will propose a multi-use project to rise in the parking lot beside the Jacob Wirth’s restaurant, on Stuart Street, in Boston’s Theater District.

Boston-based Eastat Realty Capital is planning a 326,000-square-foot development at 31-39 Stuart St. that would include a 108-room hotel, 181 housing units and ground floor retail, including a café at the Jacob Wirth Restaurant. The historic eatery near Washington Street, which specializes in German food, will undergo a major renovation as part of the proposal.

The proposal is just slightly smaller than a similar project announced last year, which met with neighborhood resistance and was ultimately canceled due to “market conditions”.
