Ayers and converted to condominiums in 1959.","why_significant":"The nomination argues it is an exceptionally well restored and well-designed early apartment building, one of Macon's first, representing the 1860s. It is also historically tied to James B. Ayers, a master builder who served as local representative and builder for the Johnston-Felton-Hay House. Its 1922 and 1959 renovations are described as in harmony with the original structure.","narrative":"Slate House is a c.1860 apartment building at 931-945 Walnut Street in Macon. Two stories tall with a daylight basement, it is a simplified Second Empire design, best known for its fish scale shingled mansard roof and segmental arched and pedimented dormer windows. A wide cornice conceals a deep gutter, and diamond-patterned holes bored in the cornice underside provide ventilation. Built and owned by master builder James B. Ayers, who served five terms as city alderman and worked on the Johnston-Felton-Hay House, it was one of Macon's first apartment buildings. Each of the four original apartments had kitchen and dining space in the basement, living space on the main floor, and bedrooms above. Renovations around 1922 and in 1959 altered the interiors and basement areas, and the 1959 work turned the building into condominiums. It was listed as an architecturally outstanding, well-restored example of adapting a century-old building to modern living.","period_of_significance":"19th Century (c. 1860)","architect_builder":"James B.
