A House with Depth｜Yu Architectural Design Studio

Situated midway along a narrow alley in a densely built residential area, this site is characterized by a narrow frontage and considerable depth, often referred to as an "unagi no nedoko" or "eel's bed" plot. The project entailed a reconstruction plan replacing a house approximately 40 years old.

The previous residence received natural light only from the south side, resulting in numerous dark spaces within the deep site. In response, this design strategically incorporates an atrium and high-side windows to ensure the entire home is filled with abundant natural light.

True to its title, "A House with Depth," the building’s form emphasizes elongation, with the interior spatial experience accentuating this depth. Specifically, the use of angled walls creates an optical illusion of perspective, expanding the perceived spatial volume and enhancing the sense of depth.

Furthermore, the use of natural materials is intended to enrich the building’s character over time through aging and patina. The design also allows for flexible modifications to the floor plan tailored to the evolving needs of the family, fostering a living environment that grows and adapts with them.
