随着出生率下降和人口老龄化加剧，空置住宅数量不断增加，在高增长时期建成的公寓大楼正在寻找重塑自我的途径。该项目为集合住宅提出了一种全新的生活方式——“合二为一”，即将大阪的一栋公寓楼中的两个居住单元合为一个单元重新使用而进行改造的创新设计。
Due to the declining birthrate and aging population, the number of vacant houses is increasing, and apartment complexes built during the high-growth period are searching for ways to reinvent themselves. This project proposes a new way of living in public housing complexes. Nikoichi is an innovative design to convert apartment complexes in Osaka(Japan), in which two dwelling units can be reused as one.

YSLA 的设计提案名为“Omoya and Hanare”，一个单元被命名为 Omoya（母屋），另一个单元被命名为 Hanare（離れ），两个单元通过外部阳台连接起来。Omoya在日语中意为房屋的核心，是主要的起居空间，而 Hanare在日语中指额外的空间，是一个独立的区域，可以有多种用途：家庭活动、学习、工作、锻炼、作为聚会场所或客人住宿。
In YSLA proposal “Omoya and Hanare”, one unit is named Omoya and the other Hanare and are connected by the exterior veranda. The Omoya, core of the house in Japanese, is the main living space and the Hanare, extra space in Japanese, is a detached area that can be used in several ways; to develop family hobbies, to study, to work, to exercise, as a place to gather or a guesthouse.

晚上到 Hanare的日式传统浴池洗个澡，身心都会焕然一新。这两个单元相辅相成，可以灵活地容纳各种的团体和/或个人。前两套公寓一套租给了有三子女的家庭，另一套则租给了三个合租的年轻人。YLSA 的“合二为一”住宅满足了出租公寓的需求，为不同人群提供了解决方案。
A night walk to the Hanare for the traditional Japanese daily bath can refresh your body and mind. These two units complement each other in a way that is flexible to accommodate a diversity of groups and/or individuals. The first two apartments were rented one to a family with three kids, and the second as a share house for three young adults. YLSA Nikoichi copes with the demand of rental apartments that can provide solutions to a divers population.
