Its landscaped acreage is screened from the green by mature trees, and is accessed via a drive on Main Street North (Connecticut Route 61).

The house consists of a 2+1⁄2-story main block, oriented facing south, with a two-story ell and modern wing to the north.

Its exterior is finished in wooden clapboards with corner quoin blocks, and there is a projecting two-story entry section in the rightmost bay.

The ell lacks evidence of a chimney adequate for cooking and heating, however, and it is more likely the house was built and occupied around 1760.

The museum features American and European antiques and a formal parterre garden with a collection of roses, peonies and lilacs.
