Thermal mass and insulation: The two-story attic (loft) design inherited from traditional local dwellings is a storage and free space all year round, and a buffer in winter and summer, which insulates the main activity spaces such as bedrooms and living room in the first floor, etc. The south-faced passive sun space in the first floor also adjusts the temperature of adjacent bedrooms and the living room.; Meanwhile, internal insulation is adopted in external walls to preserve heat, which exhibits the craft of outdoor plain brick wall at the same time.

雨污分离：实验性将卫生间分解成两个功能单元；小便功能单元居室内，大便功能单元置门房西侧，两个功能单元之间通过排污管道相连，排泄物就近排入入口院墙外的地下三格式化粪池，并定期清理；厨房、淋浴间等生活污水则就近排入后院三格式污水处理池，经人工湿地排入渗井；前后院各设集水坑，并通过雨水管道相连，前后院雨水经集水坑、雨水管道一同排放至路面雨水收集系统，分级解决雨污排放问题。

Rain and sewage separation: The toilet is experimentally designed to involve two separated functional spaces. The urine pool is placed indoor，and toilet for solid excrement is designed to the west of the hallway. Connected through the sewage pipeline, excrement is discharged into the three-cell septic tank underground which is regular cleaned-up, near the entrance wall of the dwelling. Kitchen and shower sewage is drained into a three-cell septic tank backyard, and then discharged into the dry well through artificial wetland. Meanwhile, since the house yard and back yard are equipped with puddles, connected by rainwater pipes, since rain is discharged to the road rainwater collection system through puddles and rainwater pipes , the problem of rural toileting is solved in different treatments.

乡土社会有着细密的社会交往网络和自治传统，其民居设计不受商业操纵和消费主义利用，低成本建造同样需要细节上的周到和精致。项目利用当地匠人、材料与传统工艺，从红砖的十字形砌筑、“梅花桩”砌筑到人字形砌筑，院落铺装的条形密铺与灌沙法、湿接缝法等均能凸显红砖材料工艺的功能性与艺术性；房屋木屋架采用旧屋老木料搭建，材料性能稳定，结构外露，与红砖组合，相得益彰。同时，为防止红砖饰面雨水侵蚀与反碱现象，施工增加清水砖墙面层涂刷真石漆面漆工艺；为防止冬季雨雪冻融导致红砖开裂破损，砖砌院墙、屋脊顶部增加涂抹水泥砂浆面层工艺，弥补了传统材料与工艺的缺陷。

Rural area has complex social network and unprompted tradition, thus, the design of rural dwelling is hardly influenced by commerce or mass consumer culture, this guarantees lost cost and exquisite construction details at the same time. Constructed by local craftsmen with local materials and traditional crafts, the functionality and artistry of red bricks are exhibited by the cross masonry, “plum blossom pile” and herringbone masonry, as well as the stripe paving, sand filling and wet joint method, etc. The exposed cabin frame built of old wood guarantees its stability, and complements with the red bricks. Besides, stone-like coating protects the plain brick walls against rain erosion and alkalization; Besides, cement mortar surface layer is adopted on the brick courtyard walls and roofs to prevent cracking caused by rain and snow in winter, a defect of traditional materials and technologies.

居住品质的提升源自对生活的细致品味，关中传统民居门户空间作为日常非正式交流的重要节点，项目通过主入口外倚墙砌筑红砖长凳，供左邻右舍日常休闲交流；宅院内部院落在满足农忙时节晾晒农作物主要功能时，利用一侧的树下空间形成对内的休憩场所；厨房采用砖砌炉灶与整体式橱柜，既能满足当前传统烧柴烹饪供暖的需求，亦能实现未来天然气引入后的升级换代。

The improvement of living quality comes from a thorough understanding of life. As the key space for daily communication in Guanzhong traditional dwellings, the hallway is facilitated with red brick benches against the external wall in the main entrance for daily communication among neighbors. The yard inside the dwelling is a place to dry crops in farming seasons, an internal rest space is designed under the tree. Brick stoves and internal cabinets in the kitchen enable local traditional firework cooking and heating, and prepare for the use of natural gas in future.

乡土建筑只有在地域内部得以连续发展，维持自身个性和辨识度，才能在地域之间形成多样性。咸阳·莪子村红砖房采用手工、半机械化为主的“乡村基建队”建设模式，工匠组织施工，工程总造价（不含家具、卫生器具等购置费）约31.2万元，每平方造价约1296.8元。其不再追逐落伍的时髦、乡气的都市化，拒绝对资源贪婪的消费，聚焦“文化与绿色”一体协同的营建模式，找回设计中最基本最切实际的目标，构建适宜本地区的民居营建体系，为同类型民居的新建、改扩建提供参考借鉴。

It is within the region that local architecture can be contentiously developed, the characteristics can be maintained, and regional diversity can thus be formed. The red brick dwellings in Xianyang adopt the construction mode of manual and semi-mechanized rural infrastructure team, which is organized and supervised by local craftsmen. Excluding the purchase cost of furniture and sanitary appliances，the total cost of the project is about 312,000 yuan, about 1296.8 yuan per square meter. Avoiding the old-fashioned urbanized design and excessive consumption of resources, the project develops the construction mode of integrating culture inheritance and green development, identifies the most basic and practical goal in building design, establishes a residential construction system customized for the region, and provides reference for the construction, reconstruction and expansion of dwellings of the same type.
