当顾客一迈进舒展的挑空空间入口后，映入眼帘的就是中央跨度长达7米的漩涡式旋转梯与双层空间合纵连横，与迎宾的圆形吧台交相辉映。旋转梯直达屋顶，宝马4S装修设计设置的空间轴线和视觉效果不约而同地营造了纵向的空间延伸感，并将人们的视线引向了天空和阳光射来的方向，以空间的精神力量给人以通往“上空”的无限遐想。

So when the customers enter the open space entrance, what comes into view is the whirlpool rotating ladder with a central span of up to 7 meters and a double-layer space, reflecting each other with the welcome round bar. The rotating ladder goes straight to the roof, and the space axis and visual effect create a longitudinal sense of space extension, that lead people's sight to the direction of the sky and the sun. The spiritual power of space gives people an infinite reverie to the sky.

于是最后形成了凝聚、分散、引导人流的连廊、扶梯，连通着不同楼层，产生了空间上的“合纵”与“连横”关系。

Finally, the corridor and escalator that condense, disperse and guide the flow of people are formed, which connects different floors and produces the relationship between "vertical" and "horizontal" in space.
