320 West End Avenue is one of Rosario Candela's relatively rare Upper West Side commissions — a 1924 fifteen-story boutique prewar cooperative with 31 apartments. Candela's broader Manhattan body of work — concentrated on Park Avenue and Fifth Avenue — places 320 WEA in a specific Upper West Side Candela cluster that includes 230 West End Avenue (1927) and 865 West End Avenue (1925).
The credential that anchors everything is the Rosario Candela architectural pedigree — the work of the architect Brendan Gill called, in a phrase often cited by public records, "the Michelangelo of Apartments," and a rarity on the Upper West Side at this scale. That scale matters in its own right: a boutique 31-unit configuration, small enough to support both operational intimacy and trophy full-floor layouts. And inside the apartments, the Candela interior planning discipline is unmistakable — immense rooms, grand entry galleries, formal layouts, and the "fantastic prewar details" public records broker reporting attributes to the building.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01167-0001) 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.
