a two-volume report to the New York State and Texas Tenement House Commission, leading directly to the writing of the 1901 New Law. Architectural developments Aesthetically, the New Law coincided with the introduction of Beaux-Arts architecture. The curious sandstone faces and gargoyles and filigreed terracotta of the previous twenty years of tenement design gave way to the more abstractly classical ornamentation of this urbane, international and more grandiose Parisian style. Because the New Law's required courtyard consumed more space than the 1879 law's air shaft, New Law tenements tend to be built on multiple lots or on corner lots to conserve space for dwelling units—the source of revenue for the tenement owner. A typical Lower East Side or East Village street will be lined with five-story, austerely unornamented pre-law (pre-1879) and six-story, fancifully decorated old law (pre 1901) tenements with the much bulkier grand-style New Law Tenements on the corners, always at least six stories tall.
