Besides the Callowhill Cut, another prominent curiosity in the Baldwin Park neighborhood is the granary at 411 North 20th Street. It is just north of the apartment complex named The Granary (capital letters) that was completed in 2014. The granary (lower case) was originally a wooden structure built by the Reading Company as a grain distribution center around the time of the Civil War. Grain would come into Philadelphia from central Pennsylvania farms via rail and be stored in the granary's 72 internal silos until local distribution by horse-drawn carts. The inclined railroad spur leading into the granary building is still visible along the south side of the Callowhill Cut. Trainloads of grain would come up the ramp and unload into subgrade vaults. The grain would then be elevated into the silos by a belt-driven scoop system. When grain was offloaded from the granary, carts would pull under the appropriate silo.
The original wooden granary exploded and burned in 1925. The current massive concrete structure was built that same year with the intent of being explosion-resistant. It was one of the first large reinforced concrete buildings using a slip form technique. In this method of construction, a four-foot-tall form is fitted around the foundation on all four sides. Concrete is poured into the form and rebar is added from above. The form is jacked up continuously at a rate of a few inches per hour, so that the concrete at the bottom is hard enough to resist compression free of the form. There are no joints on the building from individual forms.
Each rectangular four-foot wide silo has 15-inch thick reinforced concrete walls. For a three minute video explaining why the fine dust and air inside an enclosed building cause a risk of explosion, see outside link here.

Two things may seem evident from the granary: it is oddly placed in an urban environment and that its hulking cement frame appears indestructible. There was another granary nine blocks from ours, at 29th and Pennsylvania Avenue from the 1890s to the 1930s. This was the grain elevator for the Louis Bergdoll Brewery. The grain elevator was razed in the 1930s after the brewery failed to recover from Prohibition, but the brewery still survives as the Brewery Condominium complexes.

The pedestrian bridge is still there, but the granary is not.

Our granary stands out now only because it is the last of the Philadelphia granaries. The Tidewater Grain Company bought up many granaries in Philadelphia, including ours which was purchased from The Reading Company in 1945. The Pennsylvania Railroad also had granaries which were purchased by Tidewater. On March 28, 1956, the Tidewater granary at 31st and Market exploded, killing four. And in 2007, the Tidewater granary at Girard Point in South Philly went under the wrecking ball (after a partial implosion as seen in this three-minute video here). Granaries were common in the city, and not indestructible.

Also note the fine print: "Loss by burning, fire, or inherent explosion at owner's risk."

There are very few places you can find existing rail tracks along the Callowhill Cut and ramps. One spot is on the ramp to the granary, with rail tracks up to both former loading docks. Here you can see the north set of tracks. The south set is just out of the frame. There are also tracks under the cantilevered overhang between 18th and 19th Streets on the north side of the cut.

In 1970 the Tidewater Grain Company sold the granary to the Baltimore Warehouse Company. By 1970 the building was no longer functioning as a grain storage facility.
In 1974, after the granary had hosted a failed restaurant (called The Granary), Sonny Hopson and Perri Johnson, two local DJ's, leased the granary and turned it into The International Astro Disc. There was a kitchen and DJ, and shows at the Astro Disc were broadcast on Channel 29. Disco parties starting at midnight were not popular with the neighbors, nor with the 9th District police headquarters just across 20th Street.
Our Tidewater granary was purchased by interior designer Ken Parker in 1977 for $150,000 including liens. He used the bottom two floors for business office space and the top four stories as living space for himself. The living space offered fantastic views of the city from the rooftop garden, and the building became famous as the site of lavish parties. This reconfiguration was one of the first industrial adaptive reuse projects in Philadelphia and an early federal tax credit design.

Other water features included a koi-stocked pond visible through a glass-topped coffee table in the living room above. Peacocks roamed freely around the pond.

The metal industrial equipment seen on the north side of the building on the lower left, was installed in 1952 and was the only exterior modification made to the building since 1925. The rusted equipment was removed in 1987 for safety reasons.
The building was placed on the Philadelphia Register of Historic Buildings in 1981, and on the National Register of Historic Places one year later (for 47-page NRHP nomination form with photos from 1978 see here). Parker sold the granary in 1986 to Granary Associates, who used the building as office space until 2007 when Pearl Properties purchased the granary and the surface parking lot on Callowhill Street. The financial crisis ruined plans to build a 35 story apartment building on the lot. A plan to build a twelve story addition atop the granary was floated but encountered neighborhood opposition due to the height of the proposed building.

The next plan, in 2012, was to build a nine story apartment building on Callowhill and an eight story building on the land next to the granary and connect them with a pedestrian bridge, as discussed in an outside article here. The nine story apartment structure was opened in 2014, but the connecting structure has not been built as of yet.
The granary under Pearl Properties was still set up as potential office space, and a lease listing from 2009 shows a fairly plush interior on the bottom and top floors, as shown in these two images.

The granary had been abandoned for several years again, its stucco facade peeling off in chunks captured by the netting surrounding the building. It is on the National and Philadelphia historic registries and is headed for its 100th birthday. Building permits began appearing on the building in 2018, and by February 2021 work neared completion on a conversion to a total of 22 short-stay apartments on the upper floors (nine units on each of floors 3 and 4, and four units on floor 5) and two floors of retail on the lower floors.

Building Permit plans submitted 8/21/2019 by Granary Acquisition Partners, LP.
The plan calls for 24 apartments on the upper floors with retail on the lower two floors. The diagram in the lower right shows the layout of the grain bins, which are about four feet across with 15-inch thick walls. The angles at each intersection are buttressed to give a slightly octagonal cross-section.
The granary under its new function was christened The Tidewater Sonder, with information here. The short-stay apartment entrance is on Shamokin Street. The entrance on 20th Street leads into a Fine Wine and Good Spirits retail store.
