"An unfinished walk-out basement in a large two-story or ranch house. Basements are often left looking like this after initial construction, a cost saving move which allows for future expansion. This image would make a good starting point for a remodeling or house completion concept. The floor and right exterior wall are poured concrete, the left wall is framed, insulated and covered with plastic. The floor joists are engineered I-beams. Some broken concrete is visible behind the far wood frame wall."
