The Broad Exchange Building's articulation consists of three horizontal sections similar to the components of a column, namely a base, shaft, and capital.

[6][17] At ground level, there is an entrance portico projecting slightly from the center of the Broad Street elevation, measuring two bays wide and two stories high.

The portico consists of fluted Doric columns supporting an entablature with the text broad exchange, underneath which is a cast-iron aedicule containing the main doors.

[5][6] The six center bays at the 3rd story are topped by an alternating series of four granite modillions and three heads depicting Greek figures.

The 18th through 20th stories comprise the attic; the two outermost bays on either end of the Exchange Place and Broad Street elevations are clad with rusticated terracotta.

[21] The rear elevations are composed mostly of brick, as was the now-demolished south wing, and contain arched and rectangular window openings.

The south wing was topped by a decorative cartouche similar to those on the Exchange Place and Broad Street elevations.

[22][29] One such project was headed by the Alliance Realty Company, who hired Clinton & Russell in 1900 to design a speculative development at 25 Broad Street, near Exchange Place.

[31] In June 1900, Alliance Realty transferred ownership to the Broad Exchange Company, in which Fuller was involved, for $4 million.

[32] The Broad Exchange Company then secured a $2.25 million construction loan from the Equitable Life Assurance Society.

[52] 25 Broad Street was purchased by the City Investing Company in 1945, at which point its worth was assessed at $4.85 million.

[25] Morgan planned to replace 25 Broad Street with a new office tower to serve as its headquarters,[55][59] but put it for sale in 1981 after failing to do so.

[60] Olympia and York subsequently bought 25 Broad Street for $20.5 million,[59] also planning to build an office tower, and also failing.

[61] After the 1987 stock market crash, Neumann locked up 25 Broad Street in 1988, and the building sat empty for the next four years, during which it was looted.

[24] New West placed 25 Broad Street for sale in 1992, and the next year, Arthur Shapolsky signed a contract to buy the building for $5.8 million.

[63][62] Costas Kondylis,[16] as well as John Cetra of CetraRuddy,[64] devised a plan to renovate 25 Broad Street, in one of the first major commercial-to-residential conversion projects in Lower Manhattan.

[65] The conversion was originally supposed to be completed in 1996,[16] although a rental office opened in 1997[63] and the project was ultimately finished the next year.

[66] Around the same time that the conversion was completed, city officials were considering a plan to purchase and raze the entire block upon which 25 Broad Street was located, erecting a new New York Stock Exchange building on the site.

[66] The building was added to the National Register of Historic Places (NRHP) on April 13, 1998,[1] and was designated as a landmark by the LPC on June 27, 2000.

[69] About fifty tenants left the building after the September 11 attacks on the nearby World Trade Center in 2001, though these vacancies were quickly filled as part of a grant program to encourage people to live in Lower Manhattan.

[70] Crescent Heights put 25 Broad Street for sale in 2005,[71] and Swig Equities purchased it for $260 million,[72][73] planning to convert the building into a rental complex.

[74][75] Swig subsequently indicated plans to de-designate part of the building as a landmark, because it wished to demolish the southern wing above the first floor, transferring the air rights to its new residential skyscraper at 45 Broad Street.

[79][80] Lehman Brothers itself filed for bankruptcy in 2008, prompting Swig to close the sales office for the condos at 25 Broad Street.

[81] A court-appointed receiver designated LCOR, a subsidiary of the California State Teachers Retirement System, as the new developer for the rental project, and Lehman spent $39.9 million on preparing the building for conversion.

[82][83] In March 2011, Lehman sought permission from the judge overseeing its bankruptcy proceedings to restart work on the conversion, as well as demolish the south wing.

[83] 25 Broad Street was auctioned in 2012 as part of the foreclosure proceeding against Swig,[79] and LCOR made the winning bid of $170 million.

[10] After receiving approval from the LPC, LCOR spent another $50 million to renovate 25 Broad Street in 2013, demolishing the south wing and restoring the exterior to its early-20th-century appearance.

[86] A judge ruled in 2015 that two rental tenants could stay in their rent-stabilized apartment, since they had not been given proper notice that the exemption for their unit was expiring.

[91] In July 2020, the developers announced that 15% of the condominium units were under contract, despite a general slowdown in real estate market due to the COVID-19 pandemic in New York City.
