It now serves as accountants' offices.","why_significant":"It is an early work by Richardson and shows his grasp of French architectural ideas, recalling the Louis XIII style with red brick and light stone trim and the Neo-Grec severity he learned in Paris. It also reflects the strong influence of French culture on American taste after the Civil War. It was built for Dorsheimer, a lawyer, politician and promoter of Buffalo's park movement, who later helped bring Richardson to the Albany capitol.","narrative":"Built between 1868 and 1871 on Delaware Avenue in Buffalo, this two-and-a-half-story brick house was designed by Henry Hobson Richardson only a few years after his return from training in Paris. Its red brick walls, light sandstone bands with incised decoration, saw-tooth brick courses and straight-sided mansard roof recall the Louis XIII style and the severe Neo-Grec manner he absorbed in France. The south garden front, treated more formally than the entrance side, follows French custom. The house was built for William Dorsheimer, a lawyer, politician and journalist who promoted Buffalo's park movement and later, as lieutenant governor, helped Richardson win the commission to complete the state capitol at Albany. The house shows how French ideas shaped American taste in the Gilded Age. Though the interior has been remodeled for offices and later additions have been made, the exterior remains largely intact, and the main staircase survives from Richardson's time.","period_of_significance":"1868-71","architect_builder":"Henry Hobson Richardson, arch.","architectural_style":"Louis XIII style / Neo-Grec, French-influenced Second Empire domestic architecture","criteria":[],"status_note":"Occupied and in excellent condition; used as accountants' offices.
