Trombe Wall

The block walls - both exterior and interior - are going up rapidly.

This is the tall southern wall in the living room. The block actually looks quite a bit like granite; the mortar is a yellow/earth color that is one of the tones in the block. We're not quite certain about the mortar color - we'll live with it for a couple of weeks and see. 

This photo doesn't quite capture the color or smooth texture of the block.
