theater was completed in 1988, and a new middle school building was added in 1999. The Gateway Building, completed in 2010, contains the admission, development, college counseling and business offices, as well as the offices of Breakthrough Manchester. A new Science and Innovation Center was completed in 2019 and contains wet and dry labs, a makerspace, robotics lab, inspiration lounge, and an audio/video production studio. The grounds were expanded in 1996, when the school acquired of land, adjacent to its original parcel, from New Hampshire College (now Southern New Hampshire University). The school used this additional acreage to build six new athletic fields and a cross-country running course, allowing for the continued expansion of its athletic offerings. The Turf Field, Derryfield's premier artificial surface athletic field, was built in 2008, with floodlights added in 2009. Drainage and special snow blowing equipment make it ready to use in or after almost any weather situation. Derryfield's soccer, field hockey and lacrosse teams use it regularly, and the baseball and softball teams use it for practice when their grass fields are unplayable. The field is also used by outside clubs and teams, either for regular rental, or in the early spring, when their own grass fields may be still frozen or under water. The construction of a new athletic and wellness center was completed in November 2019. The new building is located on top of the land where the tennis courts used to be, across from the building with the old gym. Beginning in 2022, construction of a new dining hall has begun. The dining hall will be built into the athletic & wellness center, and fill the space between the center and the main school building. Athletics Derryfield offers a comprehensive interscholastic athletic and physical activity program on several levels, competing in numerous sports in both the Middle and Upper Schools during all three seasons. The Middle School teams compete in the Tri-County League, with teams from New Hampshire's Merrimack, Hillsborough and Rockingham counties. The Upper School is a New Hampshire Interscholastic Athletic Association Division IV member school, although some sports such as lacrosse and field hockey compete in higher divisions, due to the team's record of success. There are also opportunities to participate in non-team and independent sports in both the Middle and Upper Schools. Every student in grades 7–12 is required to participate in two seasons of physical activity each
