Merrill Brown and built by Albert Norris and Company Builders. Original frame of the home assembled by Kennenbec Framing Company in Maine (the same company that built the frame for Thomas Edison’s home in Fort Meyers, Florida).

Museum quality restoration and addition completed in 2010, with all systems updated to the highest contemporary standards by architect Siemasko + Verbridge and builder Gilman Guidelli.
