Honouring the legacy of the founders of the Anglo-American School of Sofia (AAS) while confidently embracing contemporary technologies, IPA – Architecture and more delivered the expansion of the existing campus, adding two new academic buildings.
Completed in 2012, the project paved the way for sustainable construction in Bulgaria and earned a LEED Gold certification. This became the first LEED-certified project by IPA – Architecture and more, while AAS emerged as the first LEED-certified school in the Balkans.
The two new wings extend the existing structure in a natural and coherent manner. They accommodate classrooms for ten cohorts of twenty students each, a library, a canteen, science laboratories, an auditorium for ceremonial and interactive learning events, a sports hall, informal learning and social spaces, as well as administrative, service, and technical facilities. The overall vision for the campus - shaped initially by the conceptual design of the American architecture company TruexCullins - was to create a unique school building with a strong connection to nature and the future.
The design by IPA – Architecture and more further developed these elements as a seamless continuation of the original structure. The terraced terrain, rather than posing a constraint, was transformed into an advantage - adding functionality and distinct character while enabling an elegant and purposeful landscape arrangement. A small amphitheatre was integrated into the grounds, flowing gently along the facade. The facade itself features extensive glazing, giving the composition a welcoming presence and ensuring generous daylight and spatial openness within. Both the exterior and interior employ a palette of soft, harmonious tones complemented by wood accents, creating a calm, friendly atmosphere with a subtle academic energy.
All facilities across the campus are designed to be energy-efficient or powered by renewable resources, in line with the client’s priority of achieving the sustainability criteria required for LEED certification.
A comprehensive water management strategy is an integral part of the project, based on the natural water cycle and the reuse of water for the school’s operational needs. This allows AAS to effectively manage rainwater, treat wastewater, and optimise irrigation costs. A green roof acts as a bio-filter: collected water is stored in a tank and pumped to the sanitary facilities for reuse. Additionally, an artificial pond incorporated into the courtyard collects surplus rainwater, supplying the irrigation system for the landscaped areas and the vegetated roof.
To maximise the building’s energy performance, the envelope is designed with high-efficiency external insulation, eliminating the need for conventional air-conditioning. Classrooms rely on natural rather than mechanical ventilation, reducing energy consumption. Significant portions of the roofs and outdoor areas are fitted with photovoltaic panels. Pathways are paved with specialised grass pavers that reduce heat absorption during the day and the subsequent release of heat at night.
