Herman B. Dahle's Neo-Classical Revival style house occupies a large, well-landscaped lot in a quiet Mt. Horeb neighborhood. Madison architect James O. Gordon designed the house for one of Mt. Horeb's most important families. Herman's father, Onon B. Dahle, a pioneer general store owner in nearby Perry Township, established the village of Daleyville. In 1895, Onon Dahle moved to Mt. Horeb, where his two oldest sons, Herman and Theodore had already started another general store in 1885. By 1895, the brothers' store was the most successful retail operation in Mt. Horeb. Onon and Herman Dahle also incorporated the State Bank of Mt. Horeb in 1891. Herman's brothers, Theodore and Henry, later joined their partnership. With the bank, the general store and their other ventures, the three brothers became the principal merchants of Mt. Horeb. It was Herman B. Dahle, however, who was the senior partner and prime mover in these projects and many others.

Herman Dahle's business success is reflected in his two-and-one-half-story-tall home, which rests on a beautifully crafted brownstone foundation. The most impressive feature of the house is its two-story porch supported by classical columns, an important feature of Neo-Classical residential design. Inside, the intact and well-maintained interior is furnished with period antiques and containing four bedrooms. The house is currently (2003) operated as the Arbor Rose Bed & Breakfast. Please respect the privacy of the residents.
