The Queen's Building, an acclaimed architectural structure, encompasses a 150-seat theatre, reception and seminar rooms, and facilities for music practice. The theatertheatre inside the Queen's Building is frequently utilized by the College for various purposes, such as lectures, Music Society concerts, admissions open day talks, and is a conference venue. Designed by the renowned architects [[Hopkins Architects | Sir Michael and Patty Hopkins]], the Queen's Building is constructed using [[Ketton limestonestone]]. The architectural design combines the robustness of the stone exterior walls with the spanning capabilities and mass of concrete for the floors. The limestone exterior is load bearing, and is the first building to use [[Stonemasonry#Post-tensioned_stone | post-tensioned stone]] with internal cables. The roof is adorned with lead, and American white oak is extensively incorporated into the roof and paneling. The building was inaugurated in 1995.
