I have commented before about the perils of over-restoration, in which a building’s owner becomes a little too enthusiastic about its preservation and ends up with a building that, except in style, looks almost new. Chelsea sits on a 500-acre preserve in Muttontown, L.I. which has come into the hands of the government of Nassau (the county on Long Island in-between Queens County and Suffolk). The county has managed to maintain the house and its grounds at exactly the appropriate level: not plastering over every crack to make it ‘good-as-new’, nor neglecting it so it becomes structurally unsound, but rather allowing it to develop and age naturally. These photographs from the ever-capable James Robertson admirably display the house and its grounds, including its shallow canal-moat.
