Craft-beer specialist Roy-Pitz Brewing Company of Chambersburg, Pa., has signed to open a brewpub at 990 Spring Garden in the Loft District.

Roy-Pitz Barrel House, which  Boxwood Architects is designing in 4,000 square feet, is on track to open in the first quarter of 2017.

Roy-Pitz's Ryan Richards and Jesse Rotz, boyhood friends who later graduated from West Chester University and opened the company in 2008, will also barrel-age sour beers. The outside of the building will be planted with live hops that will grow vertically before harvested for use in brewing.

Roy-Pitz, which refers to its beer as "liquid art" and creates some of the most beautiful labels out there, has a restaurant attached to its brewery in Chambersburg.

Roy-Pitz's commitment further bolsters the emergence of Callowhill's Spring Arts neighborhood, already home to Union Transfer and a soaring residential population.

The neighborhood also awaits the debut of the High Line-style Rail Park  and the 2017 move of Yards Brewing Company to the former Destination Maternity headquarters at Fifth and Spring Garden Streets.

Craig Grossman and Aaron Cohen of Arts + Crafts Holdings have extensively redone the building between the rail bridge and 10th Street, which was designed by Rankin and Kellogg, designers of the old 30th Street Post Office.

The building now provides loft-style space for Azavea, which specializes in geographic web and mobile software and geospatial analysis services; Boco Digital Media, which works for the biotech/pharma industries; and EducationWorks, a nonprofit.
