Permits have been issued for the construction of a four-story, 16-unit mixed-use building at 633 North 5th Street in Northern Liberties, Lower North Philadelphia. The development will apparently replace a pair of three-story prewar rowhouses situated at the southeast corner of North 5th Street and Fairmount Avenue. The new structure will span a footprint of 6,000 square feet and will hold 13,972 square feet of floor area, of which 423 square feet will be allocated for ground-floor commercial space and around 3,000 square feet for storage. The remaining square footage, totaling just over 10,000 square feet, will be residential, which translates to an average of just over 600 square feet per unit. The development will feature full sprinkling, a solar energy roof array, and indoor parking for five cars (including one accessible) and six bicycles. Permits list Volunteer for Internation.
