Springside was the estate of Matthew Vassar in Poughkeepsie, New York, United States. It is located on Academy Street just off US 9. Detailed plans for a landscape, villa, and complex of farm buildings were drawn up by the influential Andrew Jackson Downing with assistance of Calvert Vaux prior to the former's death. The landscaping was completed and remains Downing's most intact surviving landscape, but only a few of the buildings he planned were ever built; most have since been lost to fire and structural failure. A cottage where Vassar resided was dismantled and removed in the mid-1970s. Its facade is on display in the New York State Museum.

Carpenter Gothic, also sometimes called Carpenter's Gothic or Rural Gothic, is a North American architectural style-designation for an application of Gothic Revival architectural detailing and picturesque massing applied to wooden structures built by house-carpenters. The abundance of North American timber and the carpenter-built vernacular architectures based upon it made a picturesque improvisation upon Gothic a natural evolution. Carpenter Gothic improvises upon features that were carved in stone in authentic Gothic architecture, whether original or in more scholarly revival styles; however, in the absence of the restraining influence of genuine Gothic structures, the style was freed to improvise and emphasize charm and quaintness rather than fidelity to received models. The genre received its impetus from the publication by Alexander Jackson Davis of Rural Residences and from detailed plans and elevations in publications by Andrew Jackson Downing.
