Built in 1830 in Bedford, Mass., the Lewis P. Gleason Homestead was constructed as a duplex by Joshua Page, who was a prolific builder and responsible for much of Bedford’s town center.

Page is thought to have introduced the idea of the two-family home into Bedford, and many of his structures still stand today.

The Gleason Homestead, which is in the town’s downtown historic district, currently serves as a parsonage for the Congregational Church next door.
