Tianderah is a historic home located at Gilbertsville in Otsego County, New York. It was built in 1887 by Boston-based architect William Ralph Emerson. It is an "L" shaped, stone Romanesque Revival and Shingle style residence dramatically overlooking the village and complemented by a stone and shingle style stable. The house is three stories and has a steep gambrel roof, a full two stories high. It is built of rock faced bluestone and features a verandah that runs across the front of the main facade. Also on the property is a carriage shed, carriage house, and much of the original landscaping. The estate was placed on the market in July 2007 for $3 million, the highest price ever asked for a private residence in Otsego County.
It was listed on the National Register of Historic Places in 1978.
