Ivy Lodge
Why it's listed
Ivy Lodge is a two-storey house of ashlar granite in Philadelphia, Pennsylvania, designed by the architect Samuel Sloan about 1850. It is built in the Italianate style that was popular in the second quarter of the nineteenth century, a manner considered well suited to suburban houses set between city and countryside. The house has a hipped roof with large Italianate brackets supporting wide eaves. In the centre of each of its four facades, the cornice rises into a large semicircular dormer. A wooden Italianate porch runs along almost the length of two sides, and an enclosed frame bay sits on the southwest side. The plan and silhouette retain an irregularity drawn from the Gothic, while the regular window arrangement and symmetrical main facade show classical influence. Sloan is described as a major exponent of the Italianate Villa style, and Ivy Lodge is regarded as a fine example of it.
Significance in brief: The nomination describes Ivy Lodge as a fine example of the Italianate Villa style of the mid-nineteenth century. Its designer, Samuel Sloan, is described as a major exponent of that style. The house combines the regularity of classical forms with the irregular plan and silhouette associated with the Gothic.
