St. Helen's, Office skyscraper in City of London, United Kingdom
The 118-meter-tall St Helen's building contains 28 floors and features a central concrete core encased in a suspended steel framework for maximum office space.
Constructed between 1968 and 1969, St Helen's underwent major repairs after the 1992 Baltic Exchange bombing and changed ownership multiple times through the decades.
The structure incorporates design elements influenced by Ludwig Mies van der Rohe, particularly resembling New York City's Seagram Building with its geometric form.
Located at 1 Undershaft with entrance on Leadenhall Street, the building includes underground levels containing restaurants and storage facilities for office tenants.
The building earned the Civic Trust Award and Structural Steel Design Special Award in 1970 for its innovative top-down engineering construction method.
