Mixed-use residential commercial. About 10,000 square feet of commercial space on the street-level floor of the 93-year-old structure will remain, including restaurant space. About 6,000 square feet of space on the building’s basement level also is being considered for potential commercial use, according to Wishneff. NTCIC is happy to announce the successful financing of the historic Shenandoah building in Martinsburg, West Virginia. Once complete, the building is transformed into a vibrant mixed-use space in the heart of the historic Martinsburg Main Street district. This is the fourth project to utilize NTCIC’s Irvin Henderson Main Street Revitalization Fund.
