Historic Houghton Hall

Knox Campus Houghton Hall Courtyard

Houghton Hall is our dormitory for boys, houses the School’s Health and Wellness Center, kitchen and dining facilities, Solarium Art Gallery, and meeting rooms. Named for the School’s second Headmistress, Louise Phillips Houghton, this thirty-five-room Georgian Mansion was built in 1914 by politician Lathrop Brown for his estate called “Land of Clover.” The main house of the estate was designed by his brother, noted architect Archibald Brown, who modeled it after Westover Plantation in Virginia. In 1938, the property was purchased by Stephan LaRosa, who brought in materials and artisans from Italy to finish the interior spaces never completed by the Browns. The house was a summer and weekend retreat for Mr. LaRosa’s extended family until sold to The Knox School for occupancy in the fall of 1954.
