The Developer/Owner for 505 Fifth Avenue is a repeat client for Pavarini McGovern (360 Madison Avenue). The recently-completed 505 Fifth Avenue is a 275,000-SF new mixed-use office building located on the high-profile northeast corner of Fifth Avenue and 42nd Street in Manhattan, situated diagonally across from the Landmarked NYC Library and Bryant Park. The lot once held the mansion in which Edith Wharton made her society debut in 1879. The program includes retail space at the sidewalk level and in the cellar, with frontage on both Fifth Avenue and 42nd Street. The building above has multi-tenant offices in the 29-story tower with the office tower lobby accessed from 42nd Street.

The design is a reinforced concrete structural system and curtainwall, with floor to ceiling vision panels at the base and a curtainwall tower above the streetwall setback, slightly angled in plan along the Fifth Avenue façade, and both a Butt glazed glass fin and point glazed system for the storefront. A more rectilinear "spine" element sheathed in metal panel wall, housing the building's core for six elevators and two fire stairs, provides visual support of the glass elements.

This project was the recipient of NY Construction’s 2005 Merit Award/Office Project.
