Public Grand Staircase: The Street Extends Upwards

A giant public staircase climbing diagonally from the sidewalk to the building's roof. The staircase is over ten meters wide, with a middle section where people can sit and view the street. Both sides are diagonally cut concrete volumes, and the roof is an open viewing platform. People are sitting, walking, and taking photos on the staircase. The staircase itself is the facade of the building.
Avoid: making the staircase a fire escape hidden on the side of the building, setting up gates at the entrance to restrict access, making the staircase too narrow for passage, or having an empty roof platform.

一道從人行道斜斜爬上建築屋頂的巨大公共階梯。階梯寬度有十幾公尺,中段可以坐下看街景,兩側是斜切的混凝土量體,屋頂是開放的觀景平台;人群在階梯上坐著、走動與拍照。階梯本身就是建築的立面。避免:把階梯做成藏在建築側邊的逃生梯、在入口設置閘門限制進入、讓階梯寬度窄到只能通行、屋頂平台空無一物。
