It replaces a pragmatic 1960s brick structure adjacent to a 17th century stone structure by James Gibbs, holding the “Great Hall” and the famous Hogarth staircase. The building is envisioned as a “vessel within a vessel within a vessel.” The structure is a branching concrete frame, the inner layer is perforated bamboo and the outer layer is matte white glass with colored glass fragments recalling “neume notation” of Medieval music of the 13th century. The word neume originates from the Greek pnevma, which means ‘vital force.' It suggests a ‘breath of life’ that fills oneself with inspiration like a stream of air, the blowing of the wind.

The outer glass layer is organized in horizontal bands like a musical staff while the concrete structure branches like the hand. The three story centre has an open curved staircase integral to the concrete frame with open spaces vertically lined in perforated bamboo. The glass facade geometry, like a musical “staff” is in horizontal strips 90cm wide, which follow the geometry of the main stair along the north facade, while lifting up with clear glass facing the main square, marking the main front entry.

There is a second entry on the west opening to the extended garden of the adjacent church. The building tops out in a public roof garden with flowering trees open to a large room for yoga, Tai Chi, meetings etc. The interior character of this building will be shaped by colored light washing the floors and walls, changing by the time of day and season. Interior lighting is organized to allow the colored lenses together with the translucent white glass of the facade to present a new, joyful, glowing presence on this corner of the great square of St.
