The Capitol is George & Edward Blum's deliberately distinguished Carnegie Hill cooperative — designed in 1910-1912 in a Neo-Renaissance vocabulary with a glazed white terra cotta and Roman brick facade. The building was designated a NYC individual landmark in 1993 within the broader Expanded Carnegie Hill Historic District designation.
The clearest marker of the building's stature is its individual NYC landmark designation — uncommon among Carnegie Hill cross-street buildings and a signal of exceptional architectural distinction. That distinction is the product of the Blum & Blum architectural pedigree, a firm architectural historians call "one of the city's great nonconformist architectural firms," whose Beaux-Arts / Art Nouveau / Arts & Crafts hybrid practice ran across more than 120 apartment houses. Setting the building apart on a different axis is its flexible policy framework — 65% financing plus permitted pied-à-terre, gifting, co-purchasing, and guarantors, all subject to board approval.
Architectural histories document a notable construction-history fact: "During construction, the building collapsed, killing four workers" — a Blum-firm construction history milestone.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01498-0061) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.
