EuroAm’s initial findings encouraged it to do extensive research involving numerous building systems from as far afield as North and South America, and Europe where large scale housing projects are undertaken. The research identified various criteria regarding mass-housing:

• The house has to be affordable

• The house must meet a minimum quality criteria

• The project ought to create employment in the form of a "self help" programme

• The system used must be very labour intensive, but not skills intensive

• The rate of production, although using unskilled labour, must be very high, and

• There should be skills transfer

With the above criteria in mind, a couple of systems were identified and, depending on the local conditions, the suitability of a system can be agreed upon. An example of a system is the Haener Block®.
