[1] The Deering House is located on the south side of United States Route 1, a short way north of Saco's central business district.

It has a side-gable roof with a denticulated and bracketed cornice, with a front-facing gable above the centered entrance.

This house was supposedly the first in York County to have running water and indoor toilets.

Deering's heirs undertook a series of extensions and alterations to the property, hiring architects John Calvin Stevens and Joseph Stickney to design them.

[2] The library merged with the adjacent York Institute in 1976 to form the organization now known as Dyer Library/Saco Museum.
