"Holly's country seats: containing lithographic designs for cottages, villas, mansions, etc., with their accompanying outbuildings; also, country churches, city buildings, railway stations, etc., etc"[1] which was published in 1863 by D. Appleton and Co. of New York and is a pattern book of standard primarily Italianate residential designs.
In 1878 he published "Modern Dwellings in Town and Country Adapted to American Wants and Climate, with a Treatise on Furniture and Decoration"[2] by Harper and Brothers of New York.
[5] In the late 1880s he also designed a substantial mansion for the Thatcher family in Pueblo, Colorado which was demolished in the mid-twentieth century to be replaced by a hospital.
However, in 1891, Mr. Thatcher's brother, John, commissioned Holly to design his own mansion and carriage house on a nearby block.
A surviving perspective by his hand depicts a competent Gothic Revival design after the English style of residential college.
