A UU friend is building a green house near us (so we walk over periodically to see progress). It's not in cohousing. She's using Faswell block that sounds similar to Rastra Block. Faswall blocks look like concrete block but are made of specially treated wood chips and concrete and have about 4" of rockwool insulation on the outer inside edge. These block do not use mortar, instead they are stacked (not staggered), have rerod inside vetically and horizontally. After each four feet are stacked they are filled with concrete (so they are refered to as a "form" system). She has a blog with construction pictures at: http://barbsgreenhouse.blogspot.com/ Faswall is one form of Insulating Concrete Forms (ICFs) construction. http://en.wikipedia.org/wiki/Insulating_concrete_forms I think we are in a period of many different innovative construction techniques which have various advantages and disadvantages and only time and experience will tell which are optimum in what conditions.
