The Design

About Forest Archetype House

Forest Archetype is a residential project that translates the spatial order of a forest into a compact architectural form. The design is organized through a layered structural system rather than conventional room divisions. Vertical structural elements define movement and activities while maintaining visual continuity across the interior. This layered composition creates open voids and semi outdoor spaces that support flexible daily use. Through clear structural logic and spatial sequencing the house achieves richness and openness while remaining restrained in scale.

Interviews

Grand Interview

The Forest Archetype House transforms the spatial logic of an adjacent forest into a layered architectural system rather than literally reproducing natural forms, and this act of abstraction stands as one of the most intellectually compelling aspects of the project. What was the specific moment or observation during your walks through the forest that crystallized the idea of translating the vertical presence of trees into large trunk-like structural elements, and how did that conceptual leap from natural phenomenon to architectural order actually unfold in your design process?

What left the strongest impression on me while walking through the forest was not the shape of each individual tree, but the spatial density, depth, and shifting lines of sight created by the repeated vertical presence of countless trunks. At a certain moment, I felt that the trees should not be treated as decorative motifs or literal natural forms. Instead, the spatial order generated by their verticality, rhythm, and layering should be translated into architecture.From that observation, I began to develop large trunk-like structural elements that respond to the trees standing along the adjacent cliff. These elements were arranged in four layered rows, creating a spatial framework that allows the logic of the forest to continue into the interior. In addition, what I call the “forest of furniture” forms the backbone of the house, adding another layer of density and inhabitable structure.The design process was therefore not about imitating nature, but about abstracting the forest’s essential qualities: density, overlap, light, depth, and void. These qualities were transformed into an architectural order in which the family can live as if moving through the spaces between trees. Forest Archetype House seeks a condition in which nature and architecture resonate with one another—neither merely merging nor opposing, but standing independently while forming a continuous spatial experience.

Biophilic design has become one of the most discussed directions in contemporary residential architecture, yet many projects in this space rely on decorative gestures rather than genuinely restructuring spatial logic around natural principles. In what ways does the Forest Archetype House go beyond surface-level references to nature, and how do you believe the layered structural system redefines what it truly means for a home to coexist with its surrounding environment rather than simply borrow from it aesthetically?

In Forest Archetype House, biophilic design was not understood as the act of incorporating natural colors, materials, or forms into a residence. Rather, it was an attempt to translate the spatial logic of the forest itself into an architectural order. While many conventional references to nature tend to remain at the level of visual elements such as wood grain, greenery, or curved forms, this house reconstructs the repetition of trunks, density, depth, fluctuation of light, and overlapping lines of sight experienced within the forest as relationships between structure, furniture, circulation, and places to dwell.The trunk-like structural elements arranged in four layers are not merely symbolic. They serve as an architectural framework that divides space, controls views, and gently embraces the daily life of the family. Furthermore, by layering what I call the “forest of furniture” within this framework, the house becomes not a closed box, but an environment that generates a multilayered spatial experience, as if one were walking through a forest.The coexistence aimed for in this residence is not about aesthetically borrowing from the surrounding nature. It is about receiving the logic of the forest while creating an autonomous architectural order, allowing nature and human life to resonate with one another without either overwhelming the other. The essence of this project lies in treating nature not as an object to be viewed, but as a principle that forms the very structure of living.

The decision to reinforce the timber structure of the Forest Archetype House with aramid fiber sheets to address lateral forces is a technically inventive solution that bridges traditional construction materials with advanced engineering approaches. How did this structural challenge shape the overall design language of the project, and in what ways do you see this kind of hybrid material strategy influencing the broader conversation around resilient timber construction in residential architecture?

In Forest Archetype House, creating a forest-like space through large vertical elements within a wooden structure was an important theme both architecturally and structurally. At the same time, the more strongly this verticality was emphasized, the clearer the structural challenge became: how to resist lateral forces during earthquakes. The reinforcement using aramid fiber sheets was not merely a technical treatment for this issue, but an essential element in making the architectural design language possible.Through this reinforcement, it became possible to retain the mass, warmth, and physical presence of wood while incorporating the necessary structural performance within the building itself. As a result, the structural elements do not close the space as walls, but stand like tree trunks, gently dividing the interior while allowing light and lines of sight to pass through. In this sense, the structural constraint did not limit the design. Rather, it became a catalyst for strengthening the layered spatial composition of the house.In considering earthquake-resistant wooden architecture in residential design, I believe that this kind of hybrid material strategy expands the possibilities of timber construction. By combining the traditional texture and bodily quality of wood with advanced reinforcement technology, wooden architecture can achieve a freer and more delicate spatial expression. What is important is not to conceal technology, but to allow it to support the architectural concept and spatial experience at a deeper level.

Production Technology
The ceiling above the central void was finished with a low gloss metallic surface to control light reflection and enhance spatial depth.
This surface subtly reflects changes in daylight and surrounding vegetation throughout the seasons, contributing to environmental continuity without direct visual imitation.
Large suspended panels beneath the ceiling were designed as abstracted elements derived from surrounding trees, using simplified geometry and controlled spacing.
These elements modulate light, views, and scale, creating differentiated spatial conditions through material treatment rather than enclosure.
Design Challenge
The primary challenge was balancing continuity with the forest while maintaining architectural clarity and structural stability.
From a creative perspective, the project required reconciling Japanese spatial traditions, such as the fragmentation of small rooms, with contemporary residential needs.
From a technical standpoint, ensuring sufficient structural performance in a timber building led to the adoption of a reinforced frame using aramid fiber sheets to address lateral forces.
Material selection was also critical, as silver steel surfaces were carefully introduced to reflect seasonal light without overwhelming the interior.
These challenges required close coordination between design intent, structural constraints, and construction feasibility.
Research
This project is based on design research exploring residential architecture adjacent to natural forests.
The objective was to understand how built space can coexist with a forest while maintaining continuity rather than separation.
The methodology involved on-site observation, spatial analysis, and iterative design testing.
Tools included site walks, sketches, physical models, and full-scale spatial studies.
The primary participants were the architect and the future occupants.
The result was a four layered spatial system that aligns architectural elements with the scale of trees.
This research demonstrates how architectural structure can enhance daily comfort and foster a closer relationship between living space and surrounding nature.
Inspiration
This project was inspired by repeated observations of a forest adjacent to the site.
Through walking and spending time within this environment, I became aware of its spatial order, formed by the vertical presence of trees and their layered relationships.

Rather than imitating the forest as a natural form, the design seeks to abstract its vitality into a clear architectural system.
This led to the development of large, trunk like structural elements arranged in layered compositions, responding to the trees along the cliff and translating their spatial logic into architecture.
Project Duration
The project was completed in 2017 in Sapporo, Hokkaido, Japan.
Operation Flow
The house is experienced through movement rather than fixed rooms.
As occupants walk through the interior, the layered walls gradually align with the scale and rhythm of the surrounding trees.
This creates a continuous flow between inside and outside, where built elements and natural scenery visually overlap.

Living within the house involves moving through changing degrees of openness, light, and enclosure.
This interaction allows daily activities to unfold naturally, producing a calm and immersive environment that feels connected to the adjacent forest rather than separated from it.
