4,000-Sq.Ft. House Showcasing Natural Materials & Design

House Design and Its Connection to the Site

This approximately 4,000-square-foot Y-shaped house is situated in a park-like setting in a northern suburb, featuring a path alongside a small river. The house’s design allows for panoramic views of the surrounding landscape, which has been carefully developed and cultivated over more than four decades, reflecting a continuous attention to the environment and its impact on the living experience.

Integration of Art and Personal Heritage

The design emphasizes the harmony between architectural elements and art collections, drawing inspiration from the residents’ past experiences and interests in art and handcrafted antiques. It also reflects an appreciation for the family heritage linked to woodworking, creating a seamless connection between the materials used and the owner’s personal identity.

Primary Materials in the Design

The project relies primarily on just two materials: white ash wood and black sheets. These materials were selected for their distinctive physical properties, as each offers versatile possibilities for processing and shaping, allowing architects to manipulate appearance and texture to create a variety of visual effects within the design.

Diversification of Uses and Techniques

The material’s flexibility is clearly demonstrated through its various applications. The black sheets have been cut into roofing tiles, cracked to form wall stones, polished for horizontal surfaces, and crushed and compressed in the driveway. Small pieces were also gathered into mesh boxes to form supporting structures. This diversity illustrates how a single material can serve multiple aesthetic and functional purposes simultaneously, an approach often highlighted in architecture competitions and competition results.

The Impact of Natural Light on Appearance

Natural light plays a fundamental role in highlighting the materials’ characteristics. As the sun moves throughout the day, the appearance of the stone gradually changes: lines and variations become visible at certain times, while light and shadow accentuate the stone’s texture and drama at others. This interactive effect between nature and architecture demonstrates how materials can reflect light and create ever-changing sensory experiences for residents and visitors.

Aesthetic Characteristics of White Ash Wood

In contrast to the black sheets, the white ash wood panels used on the ceilings, walls, and floors were chosen for their harmonious linear appearance. This pattern imparts a calm and warm atmosphere to the space, enhancing visual harmony and psychological comfort within the environment, a principle emphasized in interior design.

Wood Treatment and Transformation

The wood was carefully treated, with primary transition points between pieces clearly defined. The wood transitions from quarter-cut to standard-cut within a uniform four-inch-wide pattern, creating a consistent visual unity despite the variety of applications, which can be referenced in material datasheets.

Integration of Wood with Art Elements

To highlight a collection of bronze casts, a fifteen-foot-long white ash wood bench was designed. This bench features cathedral-like grains and dramatic variations, giving it a unique and distinguished character even within the same type of wood used elsewhere in the space. This approach demonstrates how natural materials can interact with art elements to reinforce the visual identity of the space.

Interaction Between Interior and Exterior

Just as a slice of an apple reveals its core, each opening in the stone façade exposes the warm wooden interior. These openings were carefully designed to provide sun protection during the hot months, while the south-facing main entrance allows sunlight to enter during winter, creating a dynamic balance between light and shadow throughout the year, a concept often explored in interior design.

Glass and Views

The glass walls extend from floor to ceiling and from wall to wall, offering unobstructed, open views of the surrounding terrain. The calm, warm interior volumes frame selected outdoor scenes in a manner reminiscent of Japanese woodblock prints, connecting art with the everyday living experience.

Integrating Nature into Interior Design

The influence of the exterior environment goes beyond mere views, becoming an integral part of the interior design itself. The gardens were arranged to provide a multilayered experience from within the house, with plants and sculptural works serving as focal points in every room. In this way, the design creates a living connection between the built environment and nature, enhancing the residents’ daily quality of life by fully integrating the outdoors with the interior spaces.

✦ ArchUp Editorial Insight

It is evident that the project provides a clear example of careful attention to the interaction between natural materials and the surrounding environment, particularly in terms of natural light use and material treatment diversity, allowing architects to explore similar possibilities in their own projects. However, the project also raises several questions regarding its replicability and practical applicability on a broader scale. The extensive diversification in material use, coupled with the intensive reliance on precise detailing of wood and stone, may increase construction complexity and limit economic efficiency in larger projects or in different urban contexts.

Moreover, the focus on continuous interaction between interior and exterior, while experimentally significant, may require high levels of maintenance and precise control of light and ventilation, posing challenges for practical implementation on a wider scale. Additionally, the owners’ artistic experience and cultural references, which shaped the home’s internal identity, may render some design choices less generalizable, especially in architecture competitions or projects targeting diverse audiences or operating under limited budgets.

Nevertheless, the project remains rich in architectural insights that can inform material design and nature integration, such as studying the effect of light on stone texture or incorporating plants into interior spaces. These lessons offer a practical perspective on how to make design more responsive to the surrounding environment, even if the project itself has limited applicability on a universal scale.
