A couple of years ago we heard about apartments coming to the southwest corner of 14th and Spring, to wrap around the existing corner store and Chinese takeout. Those are making progress, there's workers out there a lot and the building is covered in tarps. Then we heard about two sets of condos coming to 14th and Quincy, a block north of Spring -- one replacing the burned C&K transient hotel, (said to include a 7-Eleven) and the other replacing the Austin Royster Funeral Home.
And recently there's new work: the house on the southeast corner of 14th and Spring, 3619 14th Street NW, was just recently demolished (seen above in progress), and workers have been gutting a house down the street at 1337 Spring. Neighbors told me the project will consist of renovations to 1337 and construction of a new building in the small, empty lot next to it, with about 6 units total.
I guess residential development is catching up to all the bars and restaurants moving northward, like Mad Momos, the Red Derby and newer spots like Lyman's and the coming Laotian restaurant, Thip Kao.
