Navajo Preparatory School Phase II Historic Academic Buildings

Three “foundation period” historic Buildings dating from 1912 to 1929 called for extensive remodeling and rehabilitation for use as 21st Century classroom space. New stacked classrooms and labs with connecting level two bridge walkways link the contemporary architectural backdrop with the rehabilitated historic structures. Construction for the new buildings was proceeded by demolition of non-significant additions on the north side of each building.  All work was planned in accordance with the Secretary of the Interior’s Standards for the Treatment of Historic Properties under Rehabilitation Standards.  

The new architecture employs an exterior material palette taken from the “transitional period” historic structures on campus, with use of cedar shakes, precast concrete and wood replacement windows in the historic structures. The original historic porches were re-constructed on the south facade of each building, providing egress and sheltered entries for each structure.

Key Design Concepts

  • Strategic rehabilitation of three historic structures
  • Passive solar design for new south facing corridors
  • Accessible level two Bridge connections between the buildings
  • Modern “gabled” classrooms set behind the historic structures
  • South facing brick pilasters reflect historic pilasters on Main Building
  • Use of historic campus materials – cedar shakes and salvaged brick
