Portner House is a low-rise, four-story condominium building completed in 1999 on the historic site of the Joseph Portner Brewing Company in North Old Town Alexandria. The boutique community of roughly 36 units blends traditional brick-and-glass façades with contemporary condo construction, and includes an elevator and secure underground parking. Unit layouts are varied — one- to three-bedroom plans ranging from standard single-level condos to rare two-story penthouses with lofted living areas and expansive private balconies. Interiors commonly feature hardwood floors, crown moldings, built-in shelving, gas fireplaces, updated kitchens with quartz or granite counters, recessed lighting, and a mix of full and ensuite bathrooms with soaking tubs and walk-in closets. Common building systems include sprinkler protection, intercom access, exterior lighting, secure storage rooms, and well-maintained sidewalks and street lighting around the property. On-site conveniences emphasize urban comfort: private garage parking (often deeded tandem or assigned spaces), storage units in the garage, in-unit laundry in most homes, and elevator access to each floor. The building’s footprint places it directly across from Trader Joe’s and steps from Harris Teeter, the Potomac waterfront and Mount Vernon bike path, multiple Metro stations, Reagan National Airport, and a dense offering of restaurants and shops, supporting a highly walkable, transit-oriented Old Town lifestyle.
