It is also an early, large-scale example of terrace-type housing, with one building nearly a quarter-mile long. It combines terrace and apartment forms and includes commercial storefronts, unlike most terraces.","narrative":"Oppmann Terrace is a group of six brick buildings on Cleveland's west side, holding 116 housing units between Detroit and Madison avenues beside West Boulevard. Built from about 1895 to about 1917, the buildings were developed by brewer Andrew W. Oppmann and his son Henry G. Oppmann. Corbelled brick parapets, segmental arched windows and repeated front porches with turned or square posts give the complex its look. The principal buildings face a long central lawn rather than a public street, and the longest building runs nearly a quarter-mile. Unlike most terraces, the units are one-floor apartments linked by shared halls, and some buildings include commercial storefronts. The complex was listed for its role in speculative multi-family housing development during Cleveland's rapid growth around 1900 and as a large example of terrace-type housing. Original window sash, porch parts and interior fixtures have been replaced, but the masonry openings, floor plans and overall design remain intact.","period_of_significance":"1895-1917","architect_builder":null,"architectural_style":"Late Victorian","criteria":["A","C"],"status_note":"Residential units remain in multiple-dwelling use; the commercial storefronts are boarded up.
