As of currently, I've not touched the sections on history and critical reception yet, but from what I have gathered the article has a number of minor issues and could do well with a bit of polishing. I'll be adding further comments as I go through the rest of the article in some time. Tayi ArajakateTalk11:27, 16 October 2020 (UTC)[reply]
As someone who doesn't understand how landfills work, the following line, "the land under the Whitehall Building was not filled until 1835, when debris from the Great Fire of New York was dumped there" could be interpreted as the debris being used to create the land instead of the land being created for dumping the debris.
The following line, "on Battery Place the original structure is composed of 12 vertical bays" is a bit confusing. Could mention that it concerns the facade facing battery place or the facade facing south.
Fixed
"The elevator lobby is the same height as the annex", this should be elevator bay or elevator lobbies, no? The citation page number for the line should also be 5–6.
Done
The conversions of imperial barrels and short tons to various units seem unnecessary, long tons and imperial gallons can be removed at least.
Done
The sectioning under History can be better stylised by ownership rather than "Construction" and "Use" since there is a bit of overlap.
Done
Could mention that the Century Realty Company was also founded by Chesebrough.
Done
The following line "In 1999 the Moinian Group paid $42 million for the basement, ground floor, and the 14th through 31st floors of the older two buildings." could state 14th to the topmost floor, since the original building ends at the 20th floor.
Done
The last line of Critical reception needs an ending quote.
Done
Issues with original research
The lead states the following, "the annex was built in 1908–1910 due to high demand for space in the original building" but the high demand is not mentioned anywhere in the body other than the bit about the original building becoming occupied so a bit unclear where this is being sourced from. On the same note, the line stating "rents per square foot at the Whitehall Building were generally lower than those on Broadway, and so the building soon became fully occupied" is cited to the Land Commission report which states that the rents were cheaper therefore it became a commercial success but not that it became fully occupied. Correct me if I'm mistaken on this, otherwise the portions needs reworking or needs to be supported with other references.
The following line under the section on Site states, "adjacent to the Downtown Athletic Club building at 18–20 West Street to the north" which refers to its adjacent building doesn't seem to be verifiable from the NYCity Map site, it gives the address of 20 West Street for that building.
The last segment under the section on Site states, "their former lands were combined to build larger commercial buildings", although intuitive, the Landmark Commission on Whitehall Building doesn't state that they were combined.
Removed
Minor, but the source cited for the following line, "the newest addition was originally called One Western Union International Plaza because Western Union employees worked there" doesn't mention anything in relation to Battery Place or Whitehall building, the citation in the next line however identifies it as 17 Battery Place North so would suggest citing it to this line as an additional reference.
Done
Issues with comprehensiveness
The lead should also include its alternative name, 17 Battery Place. The address for both the annex and the original building is the same by the way.
Done
The line, "as a result of the land filling, neighboring buildings such as 21 West Street were constructed without a basement" seems a bit off topic.
Removed
The neo-Rennasiance or Renaissance Revival style needs a mention in the section concerning design.
Done
Could possibly include information regarding the facade on the sides of the two buildings.
Done
The annex had another earlier name called Whitehall Extension which isn't mentioned.
Done
History doesn't mention the transition of ownership from United States Realty to Whitehall Improvement Company.
Done I mentioned when US Realty sold the building. I can't find when Whitehall Improvement got the building, but it was sometime before 1939. epicgenius (talk) 16:54, 17 October 2020 (UTC)[reply]
Bit unclear what happened to the Moinan Group's ownership in the original building. Also unclear if the upper floors were converted into the proposed Ocean rental-apartment.
Done It was completed in 2001, but 9/11 set renting back a little. It wasn't actually called the Ocean by the time the project was done, it was just called 17 Battery Place. epicgenius (talk) 16:54, 17 October 2020 (UTC)[reply]
Epicgenius, the Moinan Group's ownership of the upper floors in the original building is still unaccounted for. Since in the next paragraph it says SL Green sold the building to an unnamed buyer. Also the last line of history should specify that Moinan Group intends to convert 2 Washington Street into a residential structure. Tayi ArajakateTalk03:00, 18 October 2020 (UTC)[reply]
Nothing major, but regarding the bombing incident. The news report suggests that the there was bombing on both the German consulate and a smaller bombing on the office of a paper called the Communist Daily Worker, among which the latter is omitted. Seems like a interesting tidbit that can be added.

Removed Although this source does give the Downtown Athletic Club as being at 18-20 West Street, it may not be necessary for the purpose of this article. epicgenius (talk) 16:54, 17 October 2020 (UTC)
