Basic colonial revival house, 6400 block of 9th Street NW
The house being rebuilt at the corner of 9th and Tuckerman Streets NW. I think I will start calling this a tear up, because it's not a "tear down," which involves demolishing an existing house and building something bigger, usually much bigger, in its place. Instead this is a partial rebuilding of the house within the original footprint (it's probably easier to get building permits to do this), but in a way that's very much ersatz. In general the choice of materials and the sizing of architectural elements is off.
Side view. Note that this house's original design was somewhat different from the others because it is on a corner lot and they put in a side entry garage.
Use of stone for a building height extension/cornice reconstruction for an 1880s Victorian brick rowhouse on the 800 block of 4th Street NE. It probably hides a rooftop patio.
