Housing wall units were assembled in the parking lot of Landmark Christian School in Fairburn and transported to Pass Christian, Miss. After Square Foot Ministry volunteers set up the walls and roof, professionals took over the installation of plumbing and electrical systems which had to be installed to comply with local codes. SFM volunteers set up two 1,100 sq. ft. homes in two days and plan to go back in February and do it all again. Photo/Special.
