Eternal

Residential House for Metaph Architect Associates

This project draws out the potential of the construction site, proposing a house with a three-dimensional structure above and below ground on a land with a difference in elevation, creating a continuous space from underground to above ground. The floating exterior design blends into the surrounding landscape, and the windows on the south side let in views and natural light, creating an open and comfortable space. Taking into consideration the effectiveness of the site, the space was designed to achieve both an open feeling and comfort.

Unique Properties

Taking advantage of the site's elevation difference, this house creates a spatial experience that continues from underground to above ground. The distinctive floating design creates the exterior, and the open view from the south and natural light bring comfort to the residents and provide a special, eternal time. The limitations of the terrain are transformed into a rich space, making this a one-of-a-kind home that is one with nature.

Production Technology

Complex and bold spatial structures make the building unstable. In order to safely construct this open house, thorough structural analysis was carried out, and it was constructed to be strong and safe using large-section laminated timber and metal joints. In Japan, a country prone to earthquakes, where wooden structures are widely used, structural calculations are extremely important and the utmost consideration was given to them.

Design Challenge

As an urban residential area, it is the realization of a rich life that can be obtained through the openness of the house and ensures the privacy of the residents. It realizes the low carbon demand required for wooden structures and creates a design with a high degree of openness. Furthermore, it is a big challenge to ensure excellent design while ensuring earthquake resistance in Japan, a safe earthquake-resistant country.

Project Duration

The project will take place in Hyogo Prefecture, Japan, with construction commencing in September 2023 and completed in October 2024.

Operation Flow

The basement is used as a garage and hobby room. The living space is located above the first floor. It is an open house, but a large opening is placed on the south side to avoid eye contact with passersby, and because it is on high ground, it is also possible to enjoy the view.

Research

This study examines design methods aimed at achieving both safety and comfort in residential architecture with large windows, and harmonizing with the local environment. Through questionnaire surveys and tours, the aim is to investigate the psychological impact of organic architectural design that gives a sense of connection with nature, and to propose ideal residential architectural design.

Inspiration

This architecture makes the most of the elevation difference of the site, pursuing stability and harmony. Taking advantage of the elevation difference from the road, we placed volume on both the above-ground and basement levels. This allows the building to blend into the terrain, harmonizing with its surroundings while still emanating a distinctive presence. The dynamic spatial composition created by the elevation difference creates a one-of-a-kind architectural beauty.
