swing space

swing space
 n.— «Students from Spingarn Senior High would move into a new building on the school’s Northeast campus, and the old building would be used for “swing space”—housing students from other schools whose buildings are being renovated. The school system also would use Hamilton special education center in Northeast for swing space.» —“D.C. Superintendent to Propose Closing 19 More Schools” by V.
