This document summarizes a proposed new terminal building design that combines elements of circular and rectangular designs. The design aims to provide flexibility, expandability, aesthetic appeal, compactness, integrity, and allow for low-cost implementation. It is a unique shape that can address problems with existing divided and extended terminal designs. The design was tested using software to analyze its properties and capacity. Its capacity is estimated to be able to handle over five times the passengers of an existing major airport terminal while maintaining safety and functionality even at maximum expansion.
