The Glendale Power House is located southwest of Stockbridge's village center, sandwiched between Massachusetts Route 183 on the northwest bank of the Housatonic River, below the point where Glendale Middle Road crosses the river.

The power house is a single-story stone structure, three bays wide and four long, with a slate roof.

The interior is a single large chamber, which historically house turbines and electrical control equipment.

A sliding gantry-style crane provided the means to move equipment around within the building for maintenance.

[2] The power plant was built in 1905 by Monument Mills of Housatonic, at the site of a dam that dated to the 1840s for a papermaking operation.
