Built a ~ 1300 sq ft house (above ground sq ft)with finished basement (~600 sq ft). Cost a total of 350k to build without cost of the land. 100k was excavator work (septic/driveway/drainage/basement hole etc) 250k was materials and labor. I did a lot of the work myself with friends and hired a builder to put up the shell (walls, roof, decks). This was in 2012.
