The Lab School of Washington, a leading school for students with learning difficulties or disabilities, ranging from elementary to high school levels, wants to expand its high school classroom space. It plans to construct a separate high school space, next to the gym on Whitehaven Parkway. This is part of the school’s main campus at Reservoir Road and Whitehaven. School-owned houses will torn down to make way for the new building which should be ready in two years. The addition does not add any new students, as the school remains below its cap of 33o students. The school’s plans have the support of most of the neighborhood; a Board of Zoning Adjustment meeting is set for Nov. 19.
