In 2005, Loudoun County underwent its most extensive project in school history, an eighteen million dollar endeavor, which included the building of another auxiliary gym to replace the older one. The old auxiliary gymnasium turned into a new library, which used to be on the second floor. The library's area turned into a new section of classrooms, which eliminated the need for the six foundation based trailers. Additional classrooms were built adjacent to the science wing. Aerial walkways were built, connecting the separated second floors. The renovation was completed in late 2006.
