The register’s text, word for word
Description
Winterholme National Historic Site is a large, Queen Anne Revival-style residence located on a landscaped urban corner lot at 79 Rennie’s Mill Road in St. John’s.
Heritage value
Winterholme was designated in 1991 because it is a fine example of the conservative approach to the Queen Anne Revival Style in Canadian domestic architecture.
Its heritage value resides in the physical attributes illustrating a conservative example of the eclectic, picturesque Queen Anne Revival style, typical of grand homes in late nineteenth-century Atlantic Canada.
Winterholme was built by the Horwood Lumber Company in 1905-1907 as a residence for Sir Maramaduke Winter (1857-1936).

-the heavy classical cornice;
-the use of varied window forms (bow, curved and flat-headed);
-the decorative ironwork crenellation on a second floor bow window;
-the whimsical repetition of features and motifs in pairs with each paired element in a slightly different form (two articulations of curved window forms, two articulations of gables of different sizes, two iterations of a floral motifs);
-varied exterior textures (shingles, wooden clapboarding, projecting string courses, curved clear glass, stained glass);
