Notes

1. At the time of original construction it was between 37,000 sq ft (3,400 m²) and 42,500 sq ft (3,950 m²). Various sources state that it is currently 62,500 sq ft (5,810 m²) with the addition of a 20,000 sq ft (1,900 m²) 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.
