I have not received an update from Fr. Andrew yet today, but here are some pictures from Mr. Davis and Mr. Righter. Looks like the houses are coming along nicely! You can see here how the styrofoam walls are put up to give the house its shape, and then how they are covered in mortar. The mortar is made by combining dry cement, sifted sand, and water in the cement mixers, and then it is applied to the walls with trowels. You may also see video of this here (taken by Mr. Righter):
