Construction is proceeding as planned on The Heights Building, the name of the H-B Woodlawn Secondary Program’s new home at the former Wilson School site in Rosslyn.

Located at 1601 Wilson Blvd, The Heights Building will include an estimated 775 seats for students, at a cost of around $100 million. The Leo A. Daly– and BIG-designed building, with its unique stacked-rectangle design, will house both H-B Woodlawn and the Stratford Program.

H-B Woodlawn, an arts-oriented high school program with a focus on self-discipline, was once known as “hippie high.” Stratford is a secondary school for students with special needs.

Demolition for the project started in 2017.

Arlington Public Schools spokesman Frank Bellavia told ARLnow that the project remains “on schedule to open in September,” though he offered no other details on the construction progress so far.

Meanwhile, next to The Heights Building, another large construction project is underway. Excavation for the massive project — which will feature three towers, a park and a new road as part of a mixed-use development called The Highlands — appears to be mostly complete.

More from our prior coverage in October:

Work is kicking off on a massive new development in West Rosslyn, and its developer is offering a first look at its plans to build three new residential towers, a new fire station and an improved Rosslyn Highlands Park.

The D.C. developer Penzance announced today (Monday) that it would be dubbing the project “The Highlands,” which will be located at 1555 Wilson Blvd.

In all, the development will include 104 condos, 780 apartments and 40,000 square feet of retail space, including a new CVS pharmacy replacing the old shop at the location that closed earlier this year.
