I have just started building an enclosure for my Testudo tortoises (currently 0.2 T.graeca, 0.1 T.hermanni and 0.1 T.horsfieldi) It will have a greenhouse on the outside of the pen for the tortoises to use in bad weather and early spring\late fall. The greenhouse is 1,5 meter times 2,5 meter (aprox. 5 feet x 8 feet) The enclosure itelf is going to be a triangular shaped semi-concrete\mountain\wood structure. I have a few pics to begin with:
