Production Technology

Upon entering the house, two stairways immediately start, with rooms fanning out around the central courtyard. A narrow passage connects the wings at the back. Most rooms face the courtyard, allowing the sky to fill every corner. The double Möbius strip circulation and courtyard create various pathways, fostering family connections and making the space feel larger. Each room has its own path, ensuring safety during pandemics. The wings are angled at 40 degrees, enhancing the sense of space.

Design Challenge

In the suburbs of major cities, small-scale developments for mass markets dominate, leading to declining living environments. Our company resists this trend by maintaining developments at their current scale to preserve quality. For properties priced over 100 million yen, delivering value is crucial, and working with renowned architects is one approach. While spec homes make achieving ideal designs easier, strict budget constraints create constant challenges between cost and design.

Project Duration

"The collaboration between architect Shin Takamatsu and Principal Home began in 2014. We discussed the direction of the project for over a year and a half, and entered the design phase in 2015. In 2017, ""AROUND THE SKY"" was completed and received the Good Design Award. Later, in 2017, ""WITH THE SKY"" was finished, followed by the construction of ""ALONG THE SKY."" This year, the construction of two ""IN THE SKY"" buildings has also been completed."

Operation Flow

The house offers various living styles, such as centering life around the courtyard or integrating all rooms into one large space. The double Möbius strip circulation path allows for endless movement, adapting to different family activities and enriching life. Each room has its own path, so family members can live without crossing paths, especially helpful during pandemics. Natural light and air flow through the home, reducing energy dependence and making urban living more comfortable.

Research

Traditional Japanese homes, like Kyoto's machiya, were designed to bring natural elements such as light and air into daily life, even in densely built cities. These homes had a garden at their center, creating comfort, respect for nature, and a unique aesthetic. Modern homes, however, prioritize performance and have become isolated from nature, heavily relying on energy. Now is the time to revive the traditional Japanese lifestyle, reducing energy use and reconnecting with nature.

Inspiration

In the suburbs of major cities, cramped living with close neighbors is unavoidable. Modern homes prioritize energy efficiency, insulation, and privacy, resulting in inward living spaces where people often keep curtains shut to avoid outside views. Traditionally, Japanese homes embraced nature, harmonizing with the climate and reflecting a deep connection to the environment. This project aims to restore those lost values and reconnect modern living with nature.
