The Frederick Law Olmsted Summer Home, also known as Felsted, is a historic house in the town of Deer Isle, Maine.

Designed by William Ralph Emerson and built in 1897, it was for one year the summer home of the famous landscape architect Frederick Law Olmsted in a bid to improve his failing mental health.

[1] The Olmsted house is perched on rocky crag above a cove on the west side of a peninsular lobe of Deer Isle south of the village of Sunset.

It is a 2+1⁄2-story wood-frame structure, roughly T-shaped, with a hip roof across its main block and a gable section that projects over the rocky shore.

The house is characterized by numerous porches, gables, dormers, and projecting sections, with expansive use of windows to give fine views accorded by its location.
