原始空间是一个下叠的户型，一楼为卧室和餐厅，原有楼梯位置影响着整个餐厅动线和布局，楼梯位置是解决整个房屋动线最重要的问题。 设计充分利用4.8米挑高隔层，并打破地下室昏暗的刻板印象，注重垂直空间领域的融会贯通，让业主在穿行游走间，激发探索的欲望。 改造后的一楼将楼梯位置南移，扩大了餐厅的尺度，休闲阳台作为雪茄吧使用，同时在楼梯旁边拆掉了部分楼板作为地下室采光补充。 地下室通过隔层后形成挑高空间，负一层是书房，保留原始结构柱，水泥裸露的外表展现原始粗犷的力量。书桌与书柜书架形成搭接关系，书柜作为收纳功能且兼具负一层与负二层挑空区域栏杆的作用。 通过书房顺着旋转楼梯而下是负二层会客区，除了会客，在挑空区域增加水吧功能。天窗引入自然光线，增加地下室的采光和通风效果，提升使用舒适度和空间感。
The original space is a down-stacked house type, with the bedroom and dining room on the ground floor, and the location of the original staircase affects the entire dining room line and layout, and the location of the staircase is the most important issue in solving the entire house line. The design makes full use of the 4.8-metre high partition and breaks the stereotype of a dark basement, focusing on the integration of vertical space areas to stimulate the owner's desire to explore as he walks around. The ground floor was transformed by shifting the staircase to the south, enlarging the scale of the dining room, using the leisure balcony as a cigar bar, and removing part of the floor slab next to the staircase to supplement the basement's lighting. The basement is partitioned to form a high ceiling space, and the negative floor is the study, which retains the original structural columns, and the exposed concrete exterior shows the power of the original roughness. The desk is connected with the bookcase and bookshelf, and the bookcase serves as the storage function and the railing of the open area between the negative one and the negative two floors. Through the study and down the rotary staircase is the meeting area on the negative two level, in addition to meeting guests, adding the function of water bar in the open area. The skylight introduces natural light to increase the lighting and ventilation effect in the basement, which enhances the comfort and sense of space.
