Abstract: The entrance as a basic element of the building，contains the functions，moral ＆ aesthetics values，and presents variable images． It is always the focus of the building，and the joint point of the passenger flows． The transport building complex is breaking the comparatively frozen status and is transforming into a dynamic ＆ open system constituted of multiple layers ＆ elements． With the introduction of the transport features，the cohesion of space ＆ function does not only exist in the outer forms of the building，but also emerges into different parts of the transport complex． It is explored the layered transition space，features，space orientation ＆ implications resulted from the converged ＆ softened internal ＆ external interfaces，based on stereo，plane and building forms of the entrance space．
