Project Detail

Custom Features

  • 40 coloured test samples were made prior to selection via a full scale mockup
  • Curved and coloured to blend in naturally with its desert surroundings
  • Thirty differently coloured lifts with each colour specified by the architect
  • Over 100 tons of hanging rammed earth above the slot window

Technical Details

  • Largest insulated rammed earth wall in the world: 80m long, 5.5m high and 600mm thick
  • Wall is created of 150mm- to 200mm-high lifts inside 600mm- wide forms
  • Thermal resistance of the wall is R33
  • Wall is heavily reinforced and utilizes HSS frames cast in at 1200mm on centre to hang the section above the slot window from the roof slab
  • Weather conditions and extreme temperature ranges were a significant consideration (-30°C to +40°C)
  • Few control joints and very minimal non-structural random cracking

“We consider the material to have extraordinary promise from both a design and sustainability perspective, and look forward to its broader adoption.”
