Harold L. Esten, a Washington-area architect who designed and built private homes, industrial buildings, hotels, apartment buildings and shopping centers, died Feb. 19 at an assisted-living center in Fresno, Calif. He was 94.

The cause was cardiac arrest, said his son, Hugh Esten.

Mr. Esten owned Esten Associates Architects from 1955 to 1974, and his work included Nevey Shalom synagogue in Bowie, Md., and the American City Building in Columbia, Md.

In later years, Mr. Esten designed and supervised the renovation of eight Amtrak stations between Washington and Boston and taught architecture at Howard University. He returned to private practice from 1986 to 1998, with a focus on home design.

He was a longtime Silver Spring resident before moving to California in 2010.

Mr. Esten was a fellow of the American Institute of Architects, which bestowed nine design awards on him.

Survivors include his wife of 65 years, Alice McCaffrey Esten of Fresno; three children, Dora Esten and Hugh Esten, both of Los Angeles, and Amelia Ryan of Fresno; a sister; and five grandchildren.
