Located in the established suburb of Opawa in Christchurch, St Mark's is an integrated co-educational school offering a special Christian character to Year 0 - 8 children. The school caters for a maximum roll of 245 students. The school experienced significant damage in the Canterbury earthquakes with a number of buildings having to be demolished.

Signal Management Group led the preparation of a comprehensive $7M development master plan for the St Mark's School board of proprietors. Signal then subsequently managed the implementation of the master plan over a series of stages, to allow the school to be fully functional throughout the major site redevelopment.

The existing library building was damaged beyond repair and was demolished. In its place a new four teaching-space senior school building was constructed, designed to modern Innovative Learning Environment standards. The school's hall was repaired and substantially strengthened with new foundations, new floor slab and significant additional steel structure. A new stage house, music suite and toilets were also added to the building.

The school's iconic existing four-teaching space junior block and the existing middle school building housing teaching spaces, library and administration areas, were repaired, strengthened and significantly modernised.
