I’ve taken a few minutes to update our expenses. I should note that I’m including GST in all figures, until I apply for the refund.
|Tire Walls (inc. poly, Metal Lath + portland cement)||$513.04|
|Perimeter drain (inc. PVC pipe and fittings, filter cloth)||$528.46|
|Thermal Wrap (inc. poly, rigid insulation, tuck tape)||$3,769.11|
My rough estimates for our building project (minus permits) was about $5,000 to complete the drainage and the thermal wrap. So far, without our excavation time for the drainage trench, we are at $4,313.69 for these items for these two items. Based on my experience quoting out log buildings, I tend to build in a good cushion and it’s a good thing I did! I grossly underestimated the cost of the rigid insulation, thinking this would cost us about $1500. We may still have to purchase a bit more, too.
Overall, we are on budget for getting the earthship to lock up so we can work on it over winter. I’m pleased by that and hope that the roof doesn’t throw me any curveballs in terms of cost!
