Demolition has started on a century-old home along Washington Blvd in the Ballston area.

Known as the “flag house,” for the giant American flag that was often draped across it, the home was said to be in disrepair and was reportedly lacking in historic significance, following multiple additions and exterior changes.

“It is literally just an old house,” Arlington county Preservation Planner Rebeccah Ballo told us last year. “Nothing particularly noteworthy about it.”

The redevelopment plan, which was first proposed in 2013, calls for the house to be replaced by a fancy, four-story duplex. Homebuilder Wormald Homes says the new residences, at 4210 and 4214 Washington Blvd, will feature:

• Four bedrooms, four full baths and one powder room
• About 2,860 finished square feet of space
• Two car garage with two additional parking spaces
• Rear deck
• Covered front entry
• “Loft level terrace with sweeping views”
• “Classic urban design”

No word yet on when demolition is expected to wrap up or when the new building is expected to be built.
