Ross Brown of Madison County Kentucky has built a 10'x21' backyard solar greenhouse (BSGH) using the Subterranean Heating and Cooling System (SHCS). This solar-greenhouse project was inspired by

Here are some pictures of his BSGH:

The south side is raised up a few feet to give more head room; It would be too low at 10' wide otherwise because of the 45° roof angle on the south.

Note that, instead of a 60° roof angle on the north, the north wall is vertical. This allows for a higher peak for the 10' width.

Here are many construction pictures:

The walls are layered outside to inside as follows:  Hardie Board, 15-lb roofing felt, OSB board, 2'x6' studs and fiberglass insulation, 6-mil plastic VB, Hardie Board.
