The current structure, built in 1924–1925 and expanded in 1928–1929, is eight stories tall and was designed by Robert D. Kohn and Charles Butler in the Art Deco style.

The current structure replaced Namm's original building on the site when it was completed in February 1925, and it was expanded in November 1929.

The facade of the current building is divided horizontally into four sections and includes decorative features such as pilasters, balconies, and pediments.

[10][11] After relocating to Fulton and Hoyt Street, Namm gradually acquired buildings and added new selling departments to his store.

The old Zipp's Casino extended 156 ft (48 m) east to Elm Place, giving the Namm store a third entrance from that street.

[20] New York City officials approved plans for a six-story wing on Hoyt Street, south of the existing structure, in 1906.

[26] The 1907–1908 expansions doubled Namm's floor area and gave the building entrances from all sides of the city block.

[29][30] Namm's proposed erecting an eight-story wing on Hoyt and Livingston streets in May 1912,[29][30] partly on the site of a theater known as the Grand Opera House.

[31] Construction of the Hoyt and Livingston annex began the same year, with contractors completing the iron frame in five weeks.

[32][33] The Hoyt and Livingston annex officially opened in January 1913, providing additional space for the store's selling departments and offices.

[31][34] The Interborough Rapid Transit Company agreed to allow Namm's to build a subway entrance from the store's basement to the Hoyt Street station in September 1914.

The company opened a "bargain basement" that April,[41] and it hosted a groundbreaking ceremony for an annex at the corner of Elm Place and Livingston Street two months later.

[44] By then, the building occupied nearly the entire city block between Fulton, Hoyt, and Livingston streets and Elm Place, and it employed between 1,200 and 2,100 people at different times of the year.

[51] Namm's acquired three buildings on Fulton Street in June 1923[52] and issued $3.5 million of bonds the same month to fund an expansion of the store.

[65][66] The company never built the 15-story tower on Livingston Street,[56] citing the fact that the new annex was large enough for the store's operations.

[72][73] The Sorosis Shoe Company's building, which occupied the site, could not be demolished until its lease expired at the beginning of February 1929.

[95][96] Following the merger, Namm-Loeser's opened several additional stores on Long Island while maintaining the 452 Fulton Street location as its flagship.

[98] The Namm family's Arebec Corporation, which owned a 69 percent stake in the Namm-Loeser's chain,[99][100] acquired 452 Fulton Street in February 1956.

[100] Namm-Loeser's announced in February 1957 that it would close its Brooklyn store to concentrate on its eastern Long Island operations.

[99] The company held a liquidation sale that attracted thousands of patrons,[104] and the store officially closed on March 2, 1957.

[114][115] The remaining portion of the Namm building on Fulton and Hoyt streets was to be renovated with stores at ground level and offices above.

[115] The garage opened in August 1959, at which point A&S had begun moving its offices into the remaining portion of the Namm building.

[118] Crown Acquisitions, operated by developer Stanley Chera, acquired 458 Fulton Street and a small portion of the adjacent parking garage from Federated Department Stores in January 1985.

[119] The Municipal Art Society's Preservation Committee, along with local civic group Brooklyn Heights Association, began petitioning the New York City Landmarks Preservation Commission (LPC) to designate over two dozen buildings in Downtown Brooklyn as landmarks in 2003.

[56] When Namm's Fulton Street annexes were completed, few contemporary architectural publications wrote about the structures.

[97] Nonetheless, Kohn and Butler received an award from Turin's Exposition of Fine Arts in 1926 for their design of the first Fulton Street annex.

[110] In the center three bays of the Fulton Street facade, there was originally a wide ground-level entrance with two Corinthian columns,[63][64] which in turn was flanked by large storefront windows.

The eighth story is set back from the rest of the facade and contains metal railings, which run between the tops of each pier.

Above the eighth story is a parapet with crenellations that are linked by a metal-tube railing, as well as a bulkhead on the Hoyt Street side of the building.

[34][31] By the mid-1910s, the store building covered 300,000 square feet (28,000 m2) and had its own post office; 20 private telephone booths; an employees' clinic, a roof garden, reading room, and library; two escalators; 12 elevators; and entrances from the subway and from all four sides of the block.
