The construction of the three buildings that make up Morrisania Air Rights was quite the feat. Each building a different height, each building a block apart, all were built on top of pre-existing rail tracks underneath the undeveloped sections of the Metro North rail corridor, south of the famous Metro North station in Melrose. No one at the time thought that this construction could be accomplished due to the weight distribution issues. The initial designs for the units were linear to accommodate these issues, but they were not practical. Instead, in order to complete this task, the New York City Housing Authority (NYCHA) entrusted new-aged technology developed by the Massachusetts Institute of Technology. Utilizing horizontal steel trusses instead of columnns, engineers were able to ensure that construction would not interfere with the underground tracks. Not only was this the largest NYCHA housing development to date, costing the city around $35 million, it was the first time this technology was used for a residential development. The successful construction of the three buildings standing 19, 23, and 29 stories tall was completed by the architecture firm named The Eggers Partnership. Consisting of Otto and Daniel Higgins, the firm had previously constructed the Brooklyn War Memorial along with many other projects across the US and UK.
