Notes

{{reflist|group=Note|refs=

At the time of original construction it was between {{convert|37,000|sqft|abbr=on}} and {{convert|42,500|sqft|abbr=on}}. Various sources state that it is currently {{convert|62,500|sqft|abbr=on}} with the addition of a {{convert|20,000|sqft|abbr=on}} ballroom by Donald J. Trump in 2005. Since this large addition was made after the home was converted into a club in 1995, the additional space from the ballroom is not calculated into the ranking of largest houses.
