架构师提供的文本描述。如何在不改变现有架构的情况下为单个家庭住宅创建扩展？这是该项目的主要问题，客户和建筑许可证当局都明确表示了这一点。

Text description provided by the architects. How to create an extension for a single family house without altering the existing architecture? This was the main issue of the project, clearly expressed both by the clients and the building permit authorities.

扩建的项目是三间儿童卧室，一间公共游戏室和一间浴室。现有的房子是一个精心设计的建筑，从40年代后期，相当常见的郊区的斯德哥尔摩。客厅里的山墙是扩建的完美起点：一颗专为儿童设计的卫星的入口处。

The program of the extension is three bedrooms for children, a common playroom and a bathroom. The existing house is a well-drawn architecture from the late 40s, quite usual in the suburbs of Stockholm. A blind gable in the living room was the perfect start point for the extension: the entrance to a satellite designed for children.

这座新的小房子有一个倾斜的屋顶，上面覆盖着落叶松板。游戏室里有两个大的滑动窗户，把不同的层次连接到花园里。在他们中的一个旁边，一个坐椅被放置在西边的太阳上，这揭示了室内空间的重要性。

The new small house has a pitched roof and is covered with larch panel. Two large sliding windows in the playroom connect the different levels to the garden. Beside one of them, a sitting bench is placed towards the west sun, which reveals the materiality of the interior spaces.

室内空间的概念并没有反映在房子的简单的外部形状上。卧室形成不同的体积，由一个间隙空间连接在一起。

The conception of the interior spaces is not reflected in the simple exterior shape of the house. The bedrooms form different volumes connected together by one interstitial space.

这个间隙从一扇巨大的橡树门开始，宣布在老房子和新房子之间，在成人和儿童王国之间的通道。一个复杂的橡木楼梯连接了现有的房子的水平与游戏室，游戏室与楼上的卧室。这个建筑长廊遵循幼稚的规则：直线可能有点无聊，最快的方式并不总是最好玩的！螺旋运动肯定更有趣。

This interstitial space begins with a large oak door, announcing the passage between the old and the new house, between the adults and the children’s kingdom. A complex staircase of oak connects the level of the existing house with the playroom, and the playroom with the bedrooms upstairs. This architectural promenade follows childish rules: the straight line can be a little bit boring and the fastest way is not always the most playful! A spiral movement is definitely funnier.

其中一间卧室被橡木板覆盖，漂浮在游戏室上空，给人一种感觉，在这个狭小的空间里有一种魔力。

One of the bedrooms is covered with oak panel and is floating over the playroom, giving the feeling that a kind of magic is present in this tiny space.

物质性很简单：橡木和白色的表面可以很容易地随着孩子的成长而进化，而这些空间会让他们想起他们嬉戏的童年。

The materiality is simple: oak and white surfaces that can easily evolve with the growing kids, while the spaces will remind them of their playful childhood.
