To be built with CEB Press.png CEB Press IV supported by Tractor.png Prototype IV, Sawmill.png Prototype I, Rototiller.png Prototype III, Power Cube.png Prototype V and VI, Backhoe.png Prototype I, Trencher.png Prototype I, industry standard Baler.png and industry standard Chipper Hammermill.png.

Design Discussion

Notes:

Design Rationale

  • Breakthrough cost to performance ratio by DIT Collaborative Production. Goal: $4/sf.
  • Breakthrough construction time: 2 days with 5 people for every 300 square feet of house space for modular structure
    • Preframed door, window, roof. mechanical/kitchen units.
  • Modular structure, additions can be made on-demand
  • Wall-integrated Stove
  • CEB Floors
  • Double CEB Walls insulated with hammer-milled straw
  • Built-in winter-round greenhouse
  • Locally milled lumber

Design

Foundation

  • Shallow insulated footer technique. Works for heated structures to prevent frost heave.
  • Inside - poly goes under footer
  • Outside - poly goes up footer and under insulation
