@Chaitanya-Das-Ma Hi At the Mazunte workshop 35 inexperienced people got a 6m dome almost completed in a week. The organisers quote about $10,000 for a dome home (not including the cost of the footings, because it varies so much depending on the soil type). The biggest expense was for plans drawn up by a structural engineer as required by my local council. I reckon it’s costing me about $A1 a block (220 x 330mm) and I’ll need about 2500 for the 3 domes.
