The three-level facility comprises an under-croft car park, twelve classrooms, examination centre, occupied stair, break-out areas, tutorial rooms, staff offices, dining hall with associated commercial kitchen and an alfresco dining area.
Excelsior House was designed to enable students to enjoy a wide range of informal learning spaces outside of classrooms. A high level of transparency and flexibility throughout has been achieved by minimising internal columns and using operable glazed acoustic walls to all classrooms.
External materials for the building include fair-face white concrete, terracotta cladding, zinc roofing, bronze anodised window frames and bronze anodised vertical sun-breaks. Internally white painted plasterboard walls and ceilings are complemented by American White Oak timber flooring and wall panelling, grey granite flooring to specific areas and a range of highlight colours for wall fabrics and loose furniture elements.
Construction of Excelsior House commenced on site in September 2016 and the building was officially opened in March 2018.
