The William Curtis House is a historic house located at 2330 Washington Street in the Newton Lower Falls village of Newton, Massachusetts.
This -story wood-frame house was built in 1839 for William Curtis, and is an important local example of transitional Federal-Greek Revival styling. It has Federal massing, with a five bay front facade and four side chimneys, but it has Greek Revival corner pilasters, and a front entry sheltered by a Doric porch. William Curtis and his brother owned a local paper mill, which was the first in the area to install a Foudrinier machine, enabling the production of paper on rolls.
The house was listed on the National Register of Historic Places on September 4, 1986.
