Welcome to Earthcube… the fact that you’re here suggests you are seeking better build options and that’s great.
The first question asked is often “How much per square meter?” and that formula works OK on the average 3Bed with Garage etc. But when the home is smaller and intensively fitted out with quality materials as with Earthcube the formula is not really applicable. Think of Earthcube Homes as a “yacht in a box”, built to last for generations and adapt as your needs change.
A properly engineered and fitted shipping container house is around $3,500 per square meter, however in tropical locations this can be cheaper as the insulation systems are not so intense.
Have a look over the many designs and of remember of course, we prefer to individually design each home where possible.
