Local subsoil of almost any composition can be used, although an adobe mix would be preferable. A hole in the roof provided the necessary lighting and ventilation. Rammed Earth Building Technique. By the time a temporary roof was installed in 1903 the adobe building had been standing empty and unmaintained for hundreds of years.  , Although construction using the basic principles of MSE has a long history, MSE was developed in its current form in the 1960s. European settlers on the North American Prairies found that the sod least likely to deteriorate due to freezing or rain came from dried sloughs. Vernacular earth building. , In the American Civil War (1861−1865) trenches were used for defensive positions throughout the struggle, but played an increasingly important role in the campaigns of the last two years. Earth sheltered homes are bound to have dark spaces inside and for this reason, lots of lighting is essential.
