Merestead
Also known as: Sloane Estate
Why it's listed
Merestead is a 136-acre country estate near Mount Kisco in northern Westchester County, created in 1907 by William Sloane, president of the New York furniture firm W & J Sloane. Its centerpiece is a two-and-one-half-story neo-Georgian mansion of red brick with marble trim and a slate roof, designed by the architectural firm Delano & Aldrich. The firm also designed a garden house, garages and a carriage house. Sloane combined two adjacent mid-nineteenth-century farmsteads, keeping a tenant farmhouse, stable and farm sheds and adding a cow barn, so that older and newer buildings formed a single working yet picturesque farm complex. Lawns, gardens and woodlands remain in their original locations. Ten historic components make up the estate, and no non-contributing structures are reported. The property was listed because it shows, almost unchanged, how wealthy New York families set up country seats in the early twentieth century, and because it is a restrained example of Georgian-inspired design by a prominent firm.
Significance in brief: The nomination argues that Merestead is an outstanding, virtually unaltered example of an architect-designed country seat built by wealthy New York industrialists in the early twentieth century. The mansion and service buildings were designed by Delano & Aldrich, and older farm buildings were kept and blended into the estate. The original landscape of open spaces, gardens and woodlands survives, along with the overall estate ensemble.
