架构师提供的文本描述。这座20世纪20年代的小房子有一个大花园-2010年冬天被客户收购-位于亚琛市的北部周边。在这所70平米的房子上增加了一个两层50平方米的扩建部分，以满足有三个孩子的新业主家庭的空间需求。最初的建筑是一个简单的砖结构与熟料表面。设计阶段的主要问题之一是“如何扩展？”其意图是扩建和部分新建屋顶，将现有的简单建筑结构改造成一个宽敞、开放、紧凑的住宅，从而利用当代手段继承了现有材料的简单性。

Text description provided by the architects. This small 1920s estate house with a large garden - acquired by the clients in the winter of 2010 - is located on the northern periphery of the city of Aachen. A two-storey, fifty sqm extension was added to the seventy sqm house to cater to the spatial needs of the new owner family with three children. The original building is a simple brick structure with a clinker façade. One of the main questions during the design phase was, “how to extend?” The intention was that the extension and the partially new roof convert the existing simple building structure into a generous, open, compact residential home, which carried forward the simplicity of the existing materials using contemporary means.

主房子和花园在延伸的底层互相流入。这里创造了一个主要的居住空间，作为一种花园房，由于所使用的材料，它在内外之间形成了大气中介：一个开放的混凝土骨架被广泛地玻璃化，使花园和周围的景色畅通无阻。主房的东面红熟料外墙已经清理干净，作为内墙，它现在占据了“花园房”的空间特征。熟料的稀薄性与细白色浸出的木地板形成鲜明对比。

The main house and the garden flow into one another on the ground floor of the extension. A main living space has been created here as a sort of garden room, which atmospherically mediates between inside and outside as a result of the materials used: an open concrete skeleton has been extensively glazed to provide an unimpeded view of the garden and the surroundings. The east-facing red clinker outer wall of the main house has been cleaned up; as an interior wall, it now dominates the spatial character of the “garden room”. The rawness of the clinker contrasts with a fine, white-leached wooden floor.

把房子向花园延伸，把楼梯打开到楼上，用综合栏杆隔开楼梯的新墙板，改变了旧木楼梯的作用。以其牛血红色，它现在已成为最简洁的元素的中心，作为一个中心空间，慷慨连接旧的和新的建筑物，地面和顶层之间的联系。现有的红白瓷砖门楼现在就像一条地毯铺在房子中间。

Extending the house towards the garden, opening up the staircase to the upper floor and the new wall panelling of the stairs with integrated balustrade, have transformed the role of the old wooden staircase. With its oxblood red colour it has now become the most succinct element of the entrée, which, as a central space, generously connects old and new building, ground and top floor with one another. The existing red and white tiled entrance floor now lies like a carpet in the middle of the house.

沿着楼梯和天窗走到顶层，你到达了私人生活区。四间卧室各有特色，可容纳两名成人和三名儿童。一个光轴提供了一个新的，中央位置的浴室自然光。巧妙的重叠意味着浴室的天花板在原来的建筑中充当邻近儿童卧室的睡眠阁楼。分店里为男孩们建了两间房间。梯子从顶层的大厅通向阁楼，为游客提供空间、休息或储藏空间。

Following the stairs and the skylight to the top floor, you reach the private living area. Four bedrooms, each with its own character, accommodate two adults and three children. A light shaft provides natural light to a new, centrally located bathroom. Clever overlapping means that the ceiling of the bathroom acts as a sleeping loft for the neighbouring children’s bedroom, in the original building. Two rooms have been created for the boys in the extension. A ladder leads from the hall of the top floor into the attic, which provides room for visitors, retreat or storage.

原建筑的暗红色熟料外观与红褐色未抹灰浮石和扩建的轻质混凝土砖交织在一起；它以当代的方式诠释现有的材料，并与原来的颜色结合在一起，形成一个新的紧凑建筑体积。1=1。这种建筑力求专业化，而不是流线型密集化；它打破了传统的感知空间和模式，以发扬这个前工人住宅的原始、轻率的魅力。它的外观与主流明显相反，过于流畅和完美。狭小的空间已经转变成一种现代住宅的广阔而轻盈的感觉。

The dark red clinker façade of the original building interlocks with the red-brown unplastered pumice and light-weight concrete bricks of the extension; it interprets the existing material in a contemporary manner and combines with the original in colour to form a new compact building volume. 1+1=1. This architecture strives towards specialness rather than streamlined densification; it breaks conventional perception spaces and patterns to take forward the raw, brash charm of this former workers’ housing estate. Its appearance clearly stands in contrast to the mainstream too smooth and too perfect. Cramped spaces have been transformed into the expanse and lightness of a sense of contemporary dwelling.
