Should Alexandria convert vacant office space in Carlyle into senior housing?

18th Street Development LLC has asked the city of Alexandria to shift about 61,000 square feet of planned office space at 765 John Carlyle Street to residential use in the Carlyle neighborhood. The request would add 214 residential units in a proposed south tower while shrinking the office building from 12 stories to eight.

Why it matters

For Alexandria households in and around Carlyle, the change would add housing supply to a neighborhood that has been waiting for its last undeveloped parcel to be built, with a site that has sat vacant despite development approval for over 19 years. The city report cites persistent challenges in the regional office market and long-term vacancy as the reasons for repositioning the property.

The proposal covers approximately 61,000 square feet of office space and would add 214 residential units in a proposed south tower. The 12,000 square feet of approved ground-floor retail is unchanged, and the residential building would reach 220 feet while the reduced office building would stand 101 feet tall.

The Home Front

The proposal reflects the long-term vacancy of the approved Block P parcel, the last undeveloped part of Carlyle, despite more than 19 years of development approval. It shifts a stalled office plan toward housing, which the city report ties to persistent challenges in the regional office market.

If you live in or near Carlyle, watch the November 5 and November 14 meetings to see whether the added housing moves forward. Renters and buyers looking at the neighborhood should factor in that the remaining Block P parcel may bring new housing supply, though construction timing has not been set.

The takeaway

The proposal could convert a long-vacant Carlyle parcel into 214 new homes, which matters for anyone tracking local housing supply. Keep the November 5 and November 14 meeting dates on your calendar if you want to follow the outcome.
