The three-storied building, which stands at the corner of West Chestnut and North Market Streets in downtown Lancaster, was built in 1873 as a store, office and warehouse for Benjamin P Miller and John Hartman, Lancaster County's leading wholesale grocers.

Today, it is the largest intact Victorian commercial structure and the only original facade made of ornate cast iron remaining in Lancaster. The classic Italianete facade was designed by the Royer cast iron Company of Philadelphia. The building was purchased in July of 1985 and after extensive renovations it opened as the House of Pizza restaurant and lounge in February of 1986 with a seating capacity of just sixty. In the spring of 1991, the restaurant expanded into the adjoining building and by doing so, it doubled its seating capacity. The House of Pizza has been named on the "A List" of local eateries in the "Neighborhood Pizza" category by the Central Pennsylvania magazine.
