The Y-Dwelling engages with the urgent demand for innovative housing solutions in urban environments marked by narrow plots. Located in a city like San Francisco, the design explores how to create livable spaces that encourage both community and privacy. Inspired by the idea of a “California Roll,” the architecture gradually transitions from social areas to private spaces, presenting a distinct approach to residential living.

Design Concept

The core of the Y-Dwelling revolves around a spatial gradient that allows for smooth movement between communal and private zones. The design features an inviting entrance that leads to more intimate areas, offering a layered experience for residents. Strategic corners divide the interior into four sections, enhancing the interaction and sense of connection within the living space.

Functionality and Flexibility

Functionality plays a vital role in the Y-Dwelling’s design, as the interior spaces are adaptable to the needs of the occupants. Key areas for everyday activities—such as the kitchen, bathroom, toilet, and storage—are positioned thoughtfully to create transitional zones. This flexible arrangement supports the diverse lifestyles of residents, aligning with the contemporary expectations for urban living.

Construction and Materiality

Cross-laminated timber is the main construction material used in the Y-Dwelling. This choice reflects a commitment to sustainable building practices. The material contributes to the structural stability of the dwelling while also promoting an environmentally friendly approach. Its lightweight nature facilitates easy prefabrication, making it suitable for urban settings. Additionally, the use of timber is important in regions susceptible to earthquakes, providing necessary durability.

Typological Versatility

The design of the Y-Dwelling allows for various typological configurations, making it adaptable to different urban contexts. A single X-dwelling can function as a standalone villa, while multiple units can be combined to form tall structures. This versatility extends to hybrid models, where both vertical and horizontal living spaces coexist. Such options ensure that the Y-Dwelling can integrate well within the built environment, responding to the existing architectural landscape.

One notable aspect of the design is its approach to axiality. The arrangement provides clear sightlines through social and semi-private spaces, enhancing connectivity while allowing natural light to fill the interiors. This thoughtful layout creates a more inviting and airy atmosphere for residents.
