Original finishes include the wall and ceiling plaster, moldings and wide plank flooring. The staircase has a finely turned newel and balustrade. The house's kitchen wing on the south, part of its original construction, may stand on the site of an earlier house destroyed when the British burned Kingston in 1777, during the Revolutionary War. The main block has been established as built in 1803, the year the marriage of Jacob Ten Broeck and Margrit Watson, the first owners, was recorded at the Old Dutch Church. It was a monumentally scaled Federal style building, with strict attention to the hallmarks of that style, such as its proportions symmetry and classically inspired roofline details. A few decades later, modifications introduced the Greek Revival elements to the house, such as some of the interior detailing and door surrounds. In the later years of the 19th century, the frame rear and side additions were added. There have been no other modifications since its construction. It has remained a private residence for over two centuries.
