J房子的主人是一位单身教师，经过一段时间的积累，她买了一小块联排别墅用地，尺寸为4×24米。这位老师分享说，她喜欢花很多时间在家里，她有照顾花园里的植物的习惯，希望房子是明亮、通风、接近自然的。但是，联排别墅的格局宽度较窄，以J家为例是4×24米，正常的建筑方式拉伸，隔断房间会造成采光不足，通风不好，噪音大，空间也不够。花园空间供房主的爱好。

The owner of the J house is a single teacher, after a period of accumulation, she bought a small piece of townhouse land with dimensions of 4 x 24m. The teacher shared that she likes to spend a lot of time at home, and she has a habit of taking care of the plants in the garden and wants the house to be bright, airy, and close to nature. However, the townhouse layout is narrow in width, in the case of J house is 4×24 m, and the normal construction method stretches, dividing the room will cause a lack of light, poor ventilation, and noise resistance, as well as insufficient space. Garden space for the homeowner’s hobby.

在分析了联排别墅的典型缺陷后，团队在设计过程中把绿化空间、自然采光、自然通风、防噪音等标准放在了首要位置。通过工作过程，团队就布局功能的解决方案达成一致，以帮助限制联排别墅设计时的弊端。

After analyzing the typical defects of townhouses, the team put the criteria of green space, natural light, natural ventilation, and noise prevention into the top priority list in the design process. Through the process of working, the team agreed on a solution to layout functions to help limit the disadvantages when designing townhouses:

首先。在设计联排别墅的布局时，有必要确保每个功能空间必须与绿色空间（天窗、绿地）相关联。从这里开始，所有的空间都暴露在绿色植物和自然光下。

First: When designing the layout of the townhouse, it is necessary to ensure that each functional space must be associated with green space (skylight, green space). From there, all spaces are exposed to greenery and natural light.

第二：当让自然光进入房屋时，有必要计算、实验和检查现实，以调节光量，使其适合日常活动，并为绿色植物提供足够的生长和发展。在J家，太阳能玻璃被用来减少天窗区域40-45%的热量。在玻璃上方铺设石头的方案也可以调节光线，并形成遮阳。因此，室内空间始终充满了自然光，但并不热，此外，石层的阴凉创造了一种像阳光透过树叶的效果，有助于增加联排别墅空间的自然感觉。

Second: When letting natural light into the house, it is necessary to calculate, experiment, and check the reality to regulate the amount of light to be suitable for daily activities as well as provide enough for green plants to grow and develop. In the J house, solar glass is used to reduce 40-45 % of heat in the skylight area. The solution of spreading stones above the glass also regulates light and creates shade. As a result, the indoor space is always filled with natural light but not hot, moreover, the shade from the stone layers creates an effect like the sun through the leaves, helping to increase the feeling of nature in the townhouse space.

第三：在功能设计上，建立垂直和水平的两个自然通风井，确保了联排别墅的所有空间都能自然通风。位于天窗上方的Louvre Z系统有助于释放热空气，降低玻璃屋顶下方的压力。空气从前后两个门系统进入屋内，形成一股气流，在整个空间内循环，然后到玻璃屋顶下面的低压区，带走热量，向上，通过百叶窗Z逃到外面。这个过程始终保持室内空气的新鲜和凉爽。

Third: The design of functions to establish two natural ventilation shafts vertically and horizontally has ensured all spaces in the townhouse are naturally ventilated. The Louvre Z system located above the skylight helps to release hot air and reduce the pressure below the glass roof. Air enters the house from the two front and rear door systems, creating a flow of air that circulates throughout the space, then goes to the low-pressure area below the glass roof, takes the heat, upward, and through the louver Z to escape outside. This process always keeps the indoor air fresh and cool.

第四：对于靠近马路的房屋空间，经常受到交通噪音的影响，内墙采用了表面粗糙的饰面材料，天花板系统也设计成空心框架系统，有厚度，既有美观效果，又能吸音。

Fourth: For the space of the house near the road that is often affected by traffic noise, the interior walls used finishing materials that have rough surfaces, and the ceiling system is also designed as a hollow frame system, with thickness, both aesthetic effect, and noise absorption.

通过以上四个解决方案，J家变成了一个有趣而舒适的生活空间，有树，有自然光，有空气，与一般的联排别墅不同。住进新房后，在充满树木、阳光和风的生活环境中如愿以偿，老师给设计团队写了一封手写的信。这封信是一封充满深情的感谢信，分享了她享受自己宁静家园的喜悦。这一成就让大家都很高兴，也为我们的工作增添了一个特殊的时刻。

Through the above four solutions, J house has turned into an interesting and comfortable living space, with trees, natural light, and airy air, unlike a typical townhouse. After living in the new house, in a living environment full of trees, sunshine, and wind as desired, the teacher wrote a handwritten letter to the design team. The letter is a thank you full of affection, sharing the joy of enjoying her own peaceful home. This achievement makes everyone happy and adds a special moment to our work.
