The median sales price for homes in Arlington County, Va., was $551,000 in November, according to Bright MLS. For buyers with a budget capped at $400,000, that may seem as if Arlington is out of their price range. That’s especially true if they’re hoping to buy something newly built. But if they need a studio or a one-bedroom, a new condo could be affordable.

Trafalgar Flats, a new high-rise condo being built at 989 S. Buchanan St. in Arlington by Pillars Development Group, includes “junior one-bedrooms” priced from the low $300,000s and one-bedroom units priced from the mid-$300,000s. Two-bedroom condos start in the $500,000s.

The building should be ready for residents this spring, just in time for the first wave of 400 Amazon employees scheduled to relocate to the retailer’s new second headquarters in Crystal City. (Amazon founder Jeffrey P. Bezos owns The Washington Post.)

Junior one-bedrooms typically have a small den or bedroom with a sliding barn door for privacy and without a window. The condos have open floor plans with large windows in the living and dining areas, ceramic-tile flooring in the bathrooms and in-unit washers and dryers.

The kitchens have quartz counters and stainless-steel appliances. Each unit comes with a parking space in the garage.

Building amenities will include a plaza with lounge seating and a fire pit, a clubroom and a 24-hour fitness center. Residents can also reserve indoor bike storage space.

The Ballston Metro station is two miles from the condo. A bus stop for the Columbia Pike bus line is across the street from the condo to take residents to the Metro stop.

Shops and restaurants are within walking distance. The building will have ground-floor retail, and a planned future retail site on Columbia Pike is two blocks from Trafalgar Flats. In addition, Four Mile Run Park is across the street and includes access to jogging trails, athletic fields and a stream.

Monthly condo fees range from $191 to $378.
