为了重建公寓，需要把重点放在厨房和厕所上。业主希望有一个更明亮和更宽敞的厨房，每天烹饪和享受准备食物与朋友在那里。至于厕所，业主希望有一个相对独立的浴室，设有浴缸。

For reconstruction of the apartment, it is required to focus on the kitchen and toilet. The owner wishes to have a brighter and more spacious kitchen, for daily cooking and enjoyment of preparing foods with friends there. As to toilet, the owner wishes to have a relatively independent bathroom with a bathtub provided.

原来的厨房和厕所都很小，照明不足，令人不快。因此，有必要扩大厨房和厕所。然而，由于住宅建筑内几乎所有的墙都是承重的，不能拆除，所以新的内部结构的设计必须以现有的墙体结构为基础。这无疑增加了重建的难度。设计的核心是在不拆解主体墙体的情况下对厨房进行搬迁，同时厨房需要与其他功能区相结合，使公寓具有更大的容量、亮度和舒适性。而原来的厨房将被改造成浴室。卫生间和浴室设计为两个相对独立的部分。

The original kitchen and toilet are small with unpleasant insufficiency of lighting. Therefore, it is of necessity to expand the kitchen and the toilet. However, since almost all the walls inside the residential building are load-bearing and cannot be dismantled, design of the new internal organization must be based on the existing wall structure. This undoubtedly adds to the difficulty in reconstruction. The core of design is to relocate the kitchen without dismantling main wall bodies, meanwhile the kitchen need to be combined with other functional areas to make the apartment of greater capaciousness, brightness and comfort. While the original kitchen area is to be transformed the bathroom. The toilet and bathroom are to be designed as two relatively independent parts.

新公寓将有两间相对私人的卧室，以及一间公用的开放空间，可以灵活地为多种用途服务。这样设计的开放空间是为了消除空间限制，使居住者在那里做正常的日常活动时更接近对方。同时，沙发、书桌和橱柜等固定装置结合在一起，形成一个整体，靠在同一堵墙上，使公寓显得豪华，有更多的活动空间。

The new apartment will have two relatively private bedrooms, and one shared open space that flexibly serves for multiple purposes. The open space so designed is to remove spatial limitation and make the occupants closer to each other while doing the normal daily activity there. Meanwhile, fixtures such as sofa, desk and cabinet are combined to form an entirety and set against the same wall, making the apartment appear luxurious with more room for activities.
