307 Fifth Avenue is a landmark professional office building in Midtown South's Murray Hill neighborhood. Constructed in 1928 at the corner of 5th Avenue and E 31st Street, the 17-story property encompasses 64,859 square feet and recently completed a series of capital improvements. Property upgrades include a completely renovated lobby, an elevator modernization, and brand-new, double-thermal pane windows on every floor. Three sides of windows allow natural light to flood into spaces throughout the workday. Tenants benefit from responsive on-site property management and long-term, stable, family-controlled ownership. Entire 3,826-square-foot floors are immediately available for lease. Maintained in excellent condition, these entire floors feature complete office build-outs, 11-foot ceilings, private restrooms, employee kitchens, and tenant-controlled HVAC. Mass transit users are moments from multiple subway stations and bus stops and just a 15-minute walk to New York Penn Station. The property sits just two blocks from the Empire State Building, with direct access to Manhattan's best restaurants, retail, and entertainment options. 307 Fifth Avenue combines historic charm with modern upgrades, offering tenants a prime location and exceptional work environment in the heart of Midtown South.
