1728 14th Street, NW
This was the former International Union of Bricklayers and Allied Craftworkers building.
Here’s a rendering from Perseus Realty who add:
“1728 14th Street is a 35,000 square foot mixed use office and retail project located in the heart of Washington’s cultural epicenter, the 14th St corridor. Perseus Realty partnered with Ogden Capital to acquire an existing warehouse and adaptively reuse it to meet growing demand for goods and services retail and boutique office space in this corridor. The current design anticipates the first two floors as retail space with two floors of office space above. Construction is scheduled to begin by the first quarter of 2013 and will be completed by the first quarter of 2014.”
