架构师提供的文本描述。在这个项目中，公寓楼的阁楼公寓增加了一个房间。这套公寓有两层以上。楼上是起居室和厨房，下面是卧室.

Text description provided by the architects. In the project the attic apartment of an apartment house was expanded by an additional room. The apartment is conformed over 2 floors. On the upper floor there are the living-room and the kitchen, on the lower the bedrooms.

 Axonometric

由于客户希望扩展应该满足多个用途，这种扩展是有意识的，没有精确的功能。

Due to the client's wish that the  extension should meet several uses, this expansion was consciously left without precise function.

因此，额外的空间必须能够容纳各种功能，例如(客房、书房、办公室)。家具被整合到新木结构的墙壁元素中。它包含衣柜、储存空间和露天货架所需的区域。

The additional space must therefore be able to accommodate various functions such as (guest room, study, office). The furniture is integrated into the wall element of the new timber construction. It contains the required areas for wardrobe, storage space and open shelf.

也有一个空的，缩小的空间，可供用户使用的各种形式，目前用作一个办公室。

There is also an empty, reduced space that can be used by the user in various forms and  is currently used as an office.

为了给住宅小区的高密度问题提供一个合适的解决方案，满足人们对隐私的渴望，有必要预先构建一个内向的空间。新建筑背靠着露台的前缘，创造了一条通往住宅单元的新通道。除了外侧通道外，该延伸部分没有向外开放。

In order to provide a suitable answer to the problem of the high density of the residential complex and to meet the desire for privacy, it was necessary to pre-construct an introverted volume. The new construction backs up to the front edge of the terrace, creating a new access to the residential unit. Apart from the lateral access, the extension has no opening to the outside.

 Floor Plan

我们已小心尽量维持现有的架构。只有屋顶的斜坡部分需要拆除和重建。一种新型预制大体积木结构构件的设计。屋顶的其余部分都被维护好了。

Care was taken to keep the existing structure as far as possible. Only the sloping part of the roof had to be demolished and rebuilt. A new design of prefabricated mass timber construction elements. The rest of the roof was maintained.

在现有的客厅和新的房间之间，屋顶被剪掉了。庭院为室内提供日光，是住宅空间平面图中的一个组织元素。用户可以控制公共生活功能与新空间之间的视觉关系，从而在私人建筑与公共住房功能之间提供缓冲。

Between the existing living room and the new room, the roof is cut out. The courtyard provides the interior with daylight and serves as an organizational element in the open space floor plan of the residence. The visual relations between the public living functions and the new space can be controlled by the user thus providing a buffer between the private building and the public housing functions.

这种干预是可以从内部察觉到的。新的木材和混凝土部件没有经过处理。

The intervention is perceptible from the inside. The new wood and concrete components were left untreated.
