The blueprints for what will become Dupont’s best burger joint.

Mark Bucher, founder and co-owner of BGR: The Burger Joint, gave Y&H a walk-through preview of the forthcoming shop in the PNC Bank building on Dupont Circle. A preview may be something of a stretch. The site is still a construction zone.

Still, the construction site offers an interesting snapshot of the changing nature of Dupont Circle. The BGR location was, many decades ago, a residential townhouse. It’ll become a burger shop in about three weeks, Bucher promises.

Take a look at the photos after the jump.

Bucher promises that his third Burger Joint will open in about three weeks.

The Dupont location will have seating in front and back, near the rear entrance, which is right where the Dupont Circle farmers market is held each Sunday.

The kitchen will include a few stools from which you can watch the cooks grill your eight-ounce burger.

The bricks on the right provide clues as to where the stairs used to be in this former townhouse. PNC Bank now occupies the upper floor.

Whoever used to live here had classic taste in wallpaper.

The basement will serve as a prep area and as Bucher’s office.

Bucher isn’t sure how old the townhouse is, but at one point, it included a coal chute, which has now been filled with cinder blocks.
