Spirit House, also known as Timothy Brown House or Brown's Hall, is a historic home located at Georgetown in Madison County, New York.

The exterior features two-by-fours arranged vertically and scalloped at regular intervals.

The use of the scallop pattern gives the Spirit House a highly textured surface and it is almost impossible to discern how it is constructed without close inspection.

It also features a three tiered cornice with downward pointing keys.

It was constructed as a residence and for meetings of Spiritualists in a large hall on the second floor.
