Approximate assessment

The zome is now out of water and of air, there remains the insulation, the preparing and interior installation, the élec and plumbing, etc... work which will continue according to the serviceable time but one can estimate that for the expenditure and the working time, half was carried out.

If there existed in a shop, this space of more than 54 m2 of floors would cost approximately 50 000 ¤, that is to say 25 000 ¤ for half. It cost approximately 10 000 ¤ (one can add to the expenditure various expenses, displacements for the purchase of materials for example). The economy of the self-help housing is thus 15 000 ¤ . The working time representing 4 months at 35 hours per week, this corresponds to annual wages of 45 000 ¤. Not badly. This to confirm the prediction of Micmacher: "the year without wages that you pass to build your house may be the year best paid in your life!"
