Fairfax County school officials, after being rebuffed by the Board of Supervisors on a plan to renovate and buy a new administrative building, are again seeking approval after reducing the cost by millions of dollars.

The School Board has renegotiated the price tag to acquire the Gatehouse II building from $110 million to $94.5 million. The board wants to use it to consolidate administrative offices scattered throughout the county, which they argue will save money long-term and free up much-needed space for instruction.
