Q4: Off Grid - roof and final touches

Add rafters. I used the following rafter sizes

  • 50 by 50
  • 100 by 100
  • 150 by 50
  • 200 by 50

    I did this by adding beams onto beams and bolting them together. This made a shallow pitched roof, cheap, with second hand roofing sheets.

    On the corner are threaded bolts with concrete locking the top bond beams to the bottom bond beams. Poking through the roof are these thread rods holding down steel pipes and solar frame purlins, on an angle for the sun (23 degrees roughly).

    The bottom of the top bond beams are placed on chicken wire, to stop concrete poured into all cavities of the walls, the four corners are left for concrete to run down the entire channel, encasing the 12mm threaded rod in concrete.

    It takes almost a wheelbarrow load of concrete to fill a corner post, before moving along the top bond beam channel.

    The gaps between walls and roof is vermin proofed and cemented to make insect and mice proof.

    Next the door is welded and steel added with slid lock bolt for security.

    Like so, the red arrow shows cement render between walls and roof.

    The window details, and the cement render (red arrow) along roof.

    The basic power house building is complete.

    The building is weather and water proof.

    Inside is a flat ceiling, and is painted inside and out.

    The floor while a dirt floor is covered with carpet.This allows a cheap building and easy access to water pipes if needed in the future.

    The building is insect proof, fly screens add to window, and wind seals to the door.

    Next we consider the power components inside the power house.
