In a quiet residential area of Kashiwa City, Chiba Prefecture, F-WHITE emerges as a spatial response to three simultaneous conditions: a client’s desire for unity, the awkward geometry of a leftover suburban lot, and the architectural lineage of the Japanese courtyard house. Designed by Takuro Yamamoto Architects, this one-story residence challenges normative interpretations of courtyard living through a deceptively simple yet highly deliberate plan.

This oblique angle makes the courtyard look like a box which happened to be thrown out on one very large internal space.

F-WHITE Context and Design Intent
The conceptual genesis of F-WHITE was shaped by the client’s request for a spatially unified home that would not fragment the daily rhythms of a three-member family into disconnected rooms or vertical divisions. The insistence on a single-story scheme was not a stylistic preference but a spatial demand: the desire to maintain a continuous, communal living environment, resisting the compartmentalization typical of multi-story dwellings.
The site itself offered both a provocation and an opportunity. At 259.31 m², it is larger than the standard suburban plot yet unusually narrow, an irregularity that had consigned it to use as a parking lot for decades. This inherent contradiction, generous area paired with constrained proportion, led the architects to reconsider the role of central outdoor space. Rather than impose a traditional orthogonal courtyard at the heart of the dwelling, the team sought an alternate geometry to reconcile continuity with division.
Spatial Strategy and Courtyard Geometry
F-WHITE’s defining gesture lies in the courtyard’s rotation. Placed at an oblique angle within the house’s orthogonal boundary, the courtyard interrupts the expected spatial reading. This tilt is more than a formal device; it allows the surrounding interior spaces to link fluidly at their corners, bypassing the need for corridors and reinforcing a sense of spatial cohesion.
This move mitigates the typical courtyard issue in narrow lots, where the outdoor void threatens to divide rather than unify. In F-WHITE, the courtyard is perceived not as a central void to be circumnavigated but as a geometric insert, a spatial wedge around which the house unfurls. It appears almost incidental, like a box that has landed within a continuous interior shell, carving subtle niches and allowing glimpses of the sky without fracturing the whole.
Notably, the plan avoids over-articulation. Functions are assigned with clarity, yet the transitions between public and private realms are not demarcated by walls but by proximity, orientation, and visibility changes. The residence achieves a spatial sequence of unfolding rather than zoning, and each corner turned offers a fresh yet familiar perspective on the courtyard’s presence.
Material Palette and Tectonic Expression
Materially, F-WHITE adheres to a restrained palette that reinforces its conceptual clarity. The interior is defined by birch flooring, lauan plywood ceilings, and plasterboard walls finished with AEP, creating an atmosphere of calm continuity. These surfaces absorb and reflect light with subtle variation, amplifying the temporal and climatic shifts orchestrated by the central courtyard.
The mortar lysin exterior gives the house a muted, almost anonymous presence from the outside. This subdued finish resists spectacle and reinforces the introverted nature of the design; its architectural intensity is reserved for those who inhabit the space rather than those who pass by.
The project is rooted in wood-frame construction, a pragmatic and contextually appropriate choice structurally. Built by Nagano-Koumuten and furnished by Tallman STUDIO, the residence balances craft with efficiency, eschewing expressive tectonics in favor of modest precision. The architecture does not draw attention to its construction; instead, it invites attention to the voids, transitions, and relationships it enables.
