While we have observed ways in which structural engineers achieve sustainability, it remains important that we holistically understand the purpose of sustainability.

The general message remains just about the same despite the language being spoken, but the influencing factors behind sustainability will ultimately vary based on the global region.
Located on 23rd Street in Manhattan’s West Chelsea District, HL 23 sits next to and under the High Line historic railway district, which bisects the site. Completed in 2010, this project contains 14 floors and 42,000 square feet of ultra-luxury residential space with generous ceiling heights and expansive column-free zones, as well as 3,585 square feet of street level gallery space and an elevated terrace/garden area.
The HL 23 project is a testament to the versatility and beauty of steel and showcases the ability of the Owner, Architect, Structural Engineer, and Contractors to work together for inventive solutions in a unique site.

The glass mega panel system is located on the North, South and part of the East facades, with the remainder of the East façade clad with an all stainless steel system.
