Sandwich Apartment is a minimalist house located in Tokyo, Japan, designed by Ikeda Yukie Architects. Being a typically shy Japanese man, the owner wants the apartments to have privacy, yet at the same time, wants to also promote sociable exchanges between the tenants. The owner wanted to maximize the apartments buildable volume according to the law and building codes, taking advantage of the surrounding sunlight and airflow, whilst at the same time trying to reduce vertical noise.
