This is the first attempt by Mitsubishi Jisho Residences to propose an option plan for the private area that combines lifestyle, layout plan, materials, and built-in furniture into one package. In light of the COVID-19 pandemic, when people around the world began to reconsider the comfort of their living spaces, we proposed a "new standard" concept design in the post-COVID era, centering on the ideal form of residential space in an apartment, which is "a place to spend healthy and fulfilling time at home" and "the ability to balance daily life and work." The model room was the 70S1 type, which is considered the most popular family-oriented type out of the 12 types of residences on one floor. In this type, we aimed to create a living space that could be customized by the family to suit their lifestyle, and created a "multifunctional area" in the living and dining area. By dividing the large living and dining area with a shelf with storage, the family can take different actions while being in the same space, and the space allows them to feel each other's presence. The styling of the model room was based on the concept of "Japandi," and it was a proposal unique to our company, FOO, that was different from the atmosphere of previous model rooms.
